Japanese Anemone – Honorine Jobert

I have quite a large established group of white Japanese Anemone, which have developed from a couple of cuttings given to me by my Sister Cath about ten years ago. They are a bit crowded in now with a hibiscus tree and a climbing rose so I will try to propagate a few more in pots so that I can tidy up the group. The one I have is a single pure white flower with golden stamens and dark foliage. It looks like the variety called Honorine Jobert.  According to Carole Klein the variety has been around for about 150 years. It was a sport, spontaneous offspring, from the more widespread pale pink Anemone x hybrida, which was raised at the Royal Horticultural Society’s garden at Chiswick in 1848. The white-flowered sport occurred 10 years later in France on a plant that had been imported from England. Soon afterwards, Anemone ‘Honorine Jobert’ made the trip back across the Channel.

I planned to collect seed heads but even though these plants have been in my garden for so long I had never registered the seeds so I googled to find that the lovely green seed heads evident now will turn to fluffy seed which disperse themselves around the garden. I asked myself why then isn’t my garden covered in these beauties. So, I am now on seed alert as I have read that the transformation happens quickly. Update: I have collected  the seeds today 14th November. I have dropped some here and there in the garden and saved some in a brown paper envelope.

Propagation by division should be done as they start into new growth in the spring. Most nurseries raise more plants by taking roots cutting. Lift the plant in late Autumn and remove some of the thin brown roots. These are cut into sections and laid onto compost before being lightly covered. These can take months to begin to grow. These thread-like roots not only allow the plant to spread, they make it hard to eradicate a plant once it’s established. So make sure you plant your Japanese anemones where you want them as, like oriental poppies, they are difficult to eradicate. Japanese anemones can also be divided as they start into new growth in the Spring. As well as rounded white flowers it also sets seed readily. Each seed head is a little sphere held at the end of a stem. As the heads ripen they expand and their outer surface becomes soft. Eventually they erupt and each seed is carried in its own woolly overcoat to pastures new.

Agapanthus Africanus – Love Flower

I have never grown Agapanthus before. The first time I became aware of them was when my son Sean and his partner Deb came to Adam’s house to create an instantly beautiful garden when Adam received his new wheelchair and wanted to spend time outside. The Agapanthus arrived big and beautiful and smothered in vibrant blue flowers and were put in at eye level for Adam to enjoy along with many other hardy perennials. As Adam became more and more poorly and Winter arrived we spent most of the time indoors. When Adam passed away in February 2016 I came home and eighteen months have passed. On 20th August I went to the house for the twins fifth birthday and went out into the garden to see it very neglected but there were the Agapanthus with a few seed heads still containing very ripe seed. I brought a few seed heads home and was very pleased to find 80 seeds just waiting for me to sow. As I had no growing experience of these plants I had a bit of research to do. The name is derived from the Greek for Love Flower. I have 80 seeds and today, 26th August, I have sown 20 seeds in a module tray of sandy compost with a covering of horticultural grit. Germination should be around 30 days. I have just read another article which advises sowing in March so if the first 20 don’t survive I can try again in Spring.

Apparently there are seven Agapanthus species possibly because they freely hybridise. They are magnificent bulbous plants which produce an unrivalled show of blue when grown well. Their large umbels of blue trumpets are quite unlike anything else. Easily grown in well drained sunny positions. It is essential that the roots do not become waterlogged in Winter. Remember that plants grown in pots are at a risk of freezing whereas the ground usually stays above freezing point especially if the crowns are well protected with a deep mulch. Agapanthus will tolerate being overcrowded which suits them to growing in pots. If they need dividing do this in Spring and do not bury  the plants too deeply. Feed tub specimens liberally from Spring until flower bud are seen. All require full sun so the heads will naturally lean towards the sun. . In New Zealand Agapanthus grow particularly well, so well in fact that they are classified as a pernicious weed whose sale is prohibited.

Viola Sororia Albiflora – White Wood Violet

I bought an addition to my longed for Viola collection today. It is the White Wood  Violet, Viola Albiflora. This is a herbaceous perennial plant with the leaves and flowers emerging directly from the rhizomes and forming a basal rosette. A mature plant may be 6″ across and 4″ high  with the flowers rising higher than the leaves. The leaves are heart shaped as on Freckles. The flowers of this form of Viola Sororia are white except for delicate violet lines radiating from the throat of the flower. There is no noticeable scent. They flower for about six weeks emerging  from mid to late spring according to the weather. During the summer cleistogamous flowers without petals produce seeds, which are flung outward by mechanical ejection from the three-parted seed capsules. The root system consists of thick, horizontally branched rhizomes with a tendency to form vegetative colonies. As they are woodland plants they prefer dappled shade.

NB. Cleistogamy is a type of automatic self-pollination of certain plants that can propagate by using non-opening, self-pollinating flowers. Especially well known in peanuts, peas, and beans, this behaviour is most widespread in the grass family. However, the largest genus of cleistogamous plants is actually Viola.

Lavandula Stoechas Anouk – Lavender

I bought a couple of pots of this Lavender from Lidl. I think they were £2.79 each. One is here in the garden and one has gone to live with Sean and Deb. I have repotted it for now as it seemed a bit pot bound but it will go into the garden later in the year.

Lavandula stoechas is a species of flowering plant in the family Lamiaceae, occurring naturally in Mediterranean countries. An evergreen shrub, also called French or Butterfly Lavender. Anouk is a compact variety and does well in mixed containers as well as a hot, sunny border. Hardier than other forms but also easily wintered indoors. Drought tolerant once established. Flowers are attractive to butterflies. It  was developed in the Netherlands.

Prune the lavender plant in spring or early summer just after new growth begins. Pruning in autumn can cause the plant to waste energy on new growth leaving it vulnerable to frost. Do not prune lavender plants in the first year when they are establishing roots. Lavender plants, unlike many perennials, do not handle division well so cuttings is the way to go. Softwood cuttings – use only soft, new-growth material from this year that has not yet become brown and woody. These cuttings will grow fastest but are only usable if the soft material is at least 5″ long and includes at least two leafy nodes. Prepare a seed starting tray or small flowerpots to place the cuttings in for the first few weeks after cutting. Because plants without roots are sensitive to both drought and excessive moisture use a good draining compost. Use terra cotta pots due to their breathability and soak overnight before continuing to the next step. Using a clean sharp knife and  slice off the selected branch just below a leafy node, removing a cutting at least 5″ long, including at least two leafy nodes. The longer the cutting is, and the more nodes it has, the more likely it is to be successful. Leave the top cluster of leaves on as they will provide energy for the new plant. Cut all the other leaves off the cutting so that it directs its energy to root development. Plant the cuttings in the containers you prepared earlier just deep enough to keep them steady. Give them a generous quantity of water immediately after planting.  After three to six weeks strong roots will have developed in the small pot. 

 

Calla Lily Rhizomes

The calla lily grows from bulbs, more properly called rhizomes, and will, as most bulbs do, spread by producing even more bulbs. These bulbs can be divided and replanted in another location. The calla lily is a very hardy genus that will grow in more or less any soil as long as the climate is humid enough. In many of the countries where the calla lily originates it is thought of as a weed and is cut down to make way for agriculture. The calla lily can also be propagated through its seeds but it takes a little more time than just digging up the extra bulbs. I am sure that I shall try. I can’t resist seeds.

I unpacked these rhizomes today and was amazed at how big they were. I had thought that they were expensive at £3.95 for each bulb but having seen them I am filled with confidence of their success. The more I read about these fascinating plants the more I want to know. I had debated about whether to plant each bulb in a separate pot but decided in the end to put all three in a large 40cm patio pot. The directions on the pack say plant in rich potting soil and water sparingly until growth starts. Keep indoors until April and keep frost free. The three varieties that I have  planted are Auckland, a beautiful pink, Schwarzwalder, a deep almost black maroon and Albomaculata, white. I can see me buying more of these as they come in an amazing array of colours and are said to have a long flowering period. As with all bulbs grown in containers the soil needs to be changed either every year or every other year.

When grown in pots for keeping indoors the compost should be kept moist and plants should be given a weak solution of liquid plant food every three weeks while they are in growth. The best place to site them is in a west-facing window, where the air temperature does not rise much above 21°C. A south-facing window may be too hot when the sun is at its strongest in summer. Remove the flowers when they start to fade. When the plant has finished blooming, allow the leaves to turn brown, and reduce watering. Stop watering completely once all the foliage has died back.

Francis Masson, was born in Aberdeen, Scotland in 1741. In the 1760s, he went to work at Kew Gardens as an under-gardener, and was sent abroad to hunt for new plants. He sailed with James Cook on HMS Resolution to South Africa, landing in October 1772. Masson stayed there for three years, during which time he sent back to England more than 500 species of plant – including  Zantedeschia .  Information from Graham Clarke.

The red lily beetle, Lilioceris lilii,  loves the delicious lily foliage and will quickly decimate your plants. The only real answer is to seek them out and kill them. being a vivid scarlet red, they are easily spotted.  You should also look out for the eggs on the undersides of the leaves and the grubs.

Pumpkin – Mammoth, Jack o’Lantern and Snowman

Laura’s pumpkin seeds are already chitted and put into a module tray to grow on. I have put my seeds in between damp kitchen towels and in a plastic box to chit. Four Pumpkin Snowman – A beautiful snow white ornamental pumpkin that will hopefully grow to the size of a football if several fruit are left on one plant. Grow in  rich soil. Full sun, ample moisture and insect control should bring good results from this vigorous variety. Seeds and information from Seekay. Six Pumpkin Mammoth – This is a more traditional large orange fruit. Six Pumpkin Jack-o’-lantern – This is thought to be the best pumpkin for carving. Good for Halloween carving or cooking. Fruits have a round to elongated shape and taste good as well. Pumpkins are hungry feeders so a weekly dose of tomato food will help them to reach their full potential. Harvest in Autumn.

Seven of Laura’s pumpkin seedlings have gone with her friend Bryan to live with him and eventually grow in his allotment. Her other seven have been potted on and are taking over my room. My own seeds have still to germinate.

Leek Musselburgh and Porbella

4th March – I have sown seeds of Leek Musselburgh and Porbella in a pot of damp compost and placed the pot into a polythene bag. I shall keep the pot inside in the warm until germination which could be 14-21 days. The plants are intended to be put at the allotment. We have had mixed success with Leeks over the years and I am using up old seed. I still have some seeds left but I think when I use them up next year I may give this veg a miss in future. We do like to cook with leeks but they are quite cheap to buy and a bit hit and miss to grow successfully.

Sempervivum Hybridum – Hens and Chickens

I wanted to have a go at growing these unusual plants mainly because I can remember them from the garden at our prefab where I lived from the age of six months to twenty one when I left to get married. My mom always referred to them as hens and chickens. I ordered the seeds from Seekay at 99p for 250 seeds. when they came in a tiny plastic tube I was amazed at the size of the seeds. They are miniscule. Like dust. Today, 1st March, I have scattered a few onto a flat tray of sandy compost, not covered them but put the tray into a polythene sleeve and put in on the window ledge. This is another one on my wish list for around the pond. The soil is quite gritty there and I can place a few rocks for them to grow amongst. Update 7th March – Much to my surprise I was excited this morning to find that quite a few of these seeds had germinated. They are very tiny but gave me a bit of a lift this morning. 22nd March and these tiny seedlings haven’t moved on much. I have read that they are hardy plants but I suspect that the process of getting them to that point is a little more tricky.

Sempervivum hybridum is an old-fashioned favourite often seen in planters. Commonly referred to as Hens and Chicks, this perennial plant is unique and forms clusters of fleshy rosettes. The foliage colours can vary from greens to bronze-reds and all shades between. The succulent foliage spreads and produces a mat of foliage. It grows well in full sun to partial shade and prefers well-drained soil. Hens & Chicks ground cover seed can be started either indoors or directly outside. If starting inside, start the seed 6 – 8 weeks before the end of frost season. If starting outdoors, wait until frost danger has passed and soil temperatures have warmed to 70F. Press the seed into the soil but do not cover it. Keep the seed consistently moist until germination occurs which is usually within 21 days. For transplanting into the garden, wait until  after last frost and space the plants about 24 ” apart. Amazon.

Sempervivum means ‘always alive’. Also called houseleeks, Sempervivum are commonly grown in containers but they can thrive in bricks, driftwood and between rocks, due to their ability to grow in very little compost. South-facing rockeries, gravel gardens and vertical walls also make good habitats. They perform best in a sunny position in well-drained compost with sharp horticultural grit added for drainage. A layer of grit added to the surface of the compost further aids drainage.  Houseleeks are most valued for their distinctive rosettes of succulent, spirally patterned foliage, although they also bear attractive flowers from spring to summer. Each rosette is a separate plant and is monocarpic which means that it flowers once and then dies but is soon replaced by other new rosettes called offsets. These offsets can be separated and planted up, and will then grow into new clumps. Sempervivum don’t need feeding, but do benefit from being repotted each year into compost containing slow-release fertiliser. http://www.gardenersworld.com/plants/plant-inspiration/growing-sempervivums/.

Mirabalis Jalapa Marbles Mix – Marvel of Peru


Mirabilis Jalapa is an outstanding plant that will produce flowers that are marbled in colours of red, white and yellow. The flowers open in the early morning and evening , Sow seeds between February and April on the surface of a good quality seed compost and cover lightly,  Seeds can take up to a month to germinate. DO NOT EXCLUDE LIGHT as this helps germination.  Keep the compost moist but not waterlogged.  Once large enough to handle transplant into 3″ pots and grow on. When all risk of frost has passed plant out in Sunny well drained site with rich soil. Info, seeds and pictures from Seekay. Four-o-clocks are bushy annuals with colourful flowers and a sweet lemon or orange fragrance. They grow equally well in part shade as well as full sun. They begin flowering in midsummer when sown directly as seed, but will flower earlier if grown as transplants. The individual flowers open early in the morning and late afternoon and are also called four o clock flowers for that reason. They often will stay open until the following morning then close and die.  A single plant may contain different coloured flowers depending on the mix.

I received these seeds today and am looking forward to growing them. They sound very interesting. I plan to soak a few seeds overnight with a view to sowing in modules. I was pleased to learn that they have a  citrus scent too. I have sown these seeds today Wednesday 1st February and apparently they can take up to thirty days to germinate. Update – 12th March and there is one two inch seedling standing alone like a Meer cat on guard and quite a few seeds showing signs of growth. It was worth the forty day wait. 20th March I have potted on six strong seedlings.

 

 

Arenaria Montana – Mountain Sandwort

Arenaria Montana is a classic little alpine or rock garden plant. The plant has narrow, glossy green leaves that form prostrate mats of foliage that are evergreen. In mid-spring, Mountain Sandwort is blanketed by relatively large, white flowers.  Whilst it does best in full sun to partial shade, it is considered to be drought-tolerant. It is not fussy as to soil type or pH and is somewhat tolerant of urban pollution. Plants will grow to be only 2″ tall at maturity. Its foliage tends to remain low and dense to the ground and is slow growing. Their ground-hugging habit means that this useful plant can be used at the front of the border or, it can be used as a lawn substitute for low foot traffic areas. They are at their loveliest spilling over edges of walls and will quickly fill in spaces between stepping stones or trail down the sides of walls. RHS award 1993.

Sow in spring or in autumn. Prepare pots or trays with good free draining seed compost; moisten by standing in water, then drain. Surface sow two seeds per pot or cell and press them gently down to firm them in. Cover the seed with a fine layer of vermiculite if you have it.  Seal pots in a polythene bag or cover trays with clear plastic lids until after germination. It is important to keep soil slightly moist but not wet. Remove the covering once the first seedlings appear. Germination can take up to 30 days. If seeds do not germinate by 4 weeks remove pots/tray to a cool shaded area. Seedlings are usually large enough to handle after 4 weeks. Transplant the seedlings into 3½” pots. Two seedlings can be planted to one pot. Place the pots in a cold frame or unheated greenhouse to grow on.  Before transplanting outdoors, harden off gradually. They do best in moist but well draining soils.

Arenaria Montana has a shallow root system and can dry out very quickly. Cover substrate with vermiculite or mulch to retain water and keep your eye on small plants until they establish themselves. A relatively low maintenance perennial, simply remove damaged foliage in spring and fertilise with a complete balanced fertiliser, don’t fertilise after mid September. It should only be pruned after flowering to avoid removing any of the current season’s flowers.

Arenaria Montana is native to mountainous regions of south-western Europe from the Pyrenees of France to Portugal.

The genus name Arenaria is taken from the Latin arena meaning sand referring to the sandy habitats of many species. The species name Montana means simply ‘of the mountains’. Arenaria Montana is a member of the Caryophyllaceous family, a cousin of the popular Dianthus genus.

Today, 6th February, I sowed all twenty seeds received from Seekay at a cost of £1.22, I put them two to a module. Now I must wait for thirty days for germination. From past experience I know that Alpines aren’t easy to grow. We are planning on rebuilding the area around our old pond this year and these were  something I thought would be good there. Update 16th Feb – three green shoots showing after ten days.
