This beautiful alpine was sent to me yesterday from Deb along with quite a few other surprise plants. Strangely enough I had bought myself one earlier in the year and had lost it during the long hot spell we had recently. Its common name is Rock Rose and it is described as good ground cover and as a hardy plant once established.
This is an evergreen mat forming perennial producing masses of rose pink flowers over grey green foliage and is suitable for the rockery, as ground cover in the borders, or in gravel gardens. It is equally at home in a container.
The advice is when newly planted always keep watered until the roots have grown down and it is able to find its own moisture. Trim after flowering to maintain a good shape.
Gypsophila cerastioides is native to the rocky slopes of the eastern Himalayas and forms an attractive tuft with shiny green foliage and pink-veined white trumpet flowers. Also known as Alpine Baby’s Breath this rock garden plant likes the sun and light, well-drained soil. Can also be grown in troughs. A hardy perennial, this small type of Gypsophila is drought tolerant, tough and produces endless supplies of white flowers, which are loved by butterflies. The Mouse Eared Gypsophila is good for alpine gardens, rockeries, patio containers, troughs or for growing in gaps in walls and paving. The tufted, mounding plants produce flowers from spring to summer. It seems like an ideal plant for around the pond one day.
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.
