How To Grow Sisyrinchium From Seed

Sisyrinchium striatum are upright architectural plants with spires of yellow-white flowers in May and June. This video shows mature clumps of Sisyrinchium plants with late-season seed heads and now is still a great time to collect and sow Sisyrinchium seeds that will reliably germinate into new Sisyrinchium plants before the winter sets in.
In the UK Sisyrinchium striatum are short-lived perennials lasting no more than 3-4 years, after this, they tend to lose their vigor and die out from the crown, so it's a great idea to regularly replace older Sisyrinchium plants with young specimens to keep both the healthy-looking foliage and flower volume up.
Sisyrinchium seeds can be sown as soon as collected, and germination of the Sisyrinchium seeds varies between a couple of weeks and a few months depending on temperature and moisture,. This season's germination of Sisyrinchium seed was delayed by the drought here in Norfolk, but we are now getting a proliferation of Sisyrinchium seedlings appearing from Sisyrinchium seeds that naturally scattered and self seeded in July and August.
