I have finally bought some seeds of Gaura lindheimeri or Whirling Butterflies. I saw these in a garden on the estate last year and they were immediately on my wish list. The plants were a bit out of my price range so I started the hunt for some reasonably priced seeds. Today I have sown three seeds each in two ten inch pots and after a good watering Laura has put them into her greenhouse so fingers crossed. Germination could be anything from 14-28 days. I don’t expect to see any flowers this year but if I can get a couple of good plants for next year flowering I shall be happy. I bought 30 seeds from Johnsons for £2.40. Apparently Gaura is a late performer so it tends to be put into the ground too early and too small. The time to bring on your Gaura is in July as a well-grown pot plant. It is said to self seed freely and as it is also short lived I intend to let some seed fall and save some to sow myself.
Update on 12th August 2018 – I have four healthy seedlings. All I have to do now is get them through the Winter.
Update 18th July 2019. – Two plants have survived and are now in the garden. One in the ground and the other in a large planter.
A fully hardy, graceful, hazy plant with airy spikes of white, star-shaped flowers with long anthers held on slender stems from May to September. This exceptionally long-flowering perennial looks equally at home in an informal cottage-style garden or among soft grasses in a new perennial border. It is exceptionally drought-tolerant and will soak up the sun. Give it space as its wispy stems will lean over plants and pathways. Resist the temptation to cut back after the plant has flowered as it takes on beautiful autumn tints, particularly in cold weather. Cut back and divide large colonies in spring. information from Crocus.com. Can’t wait.
