READY LATER IN THE SEASON. A peculiar plant, in the best sense of the word. Sisyrinchium Biscutella reminds us of a spider, somehow, perhaps because the buff flowers, which are streaked with purple, are held in clusters on long stems. You'll see what we mean. The flower stems arise from evergreen clumps of rather grass-like elongated mid-green leaves and provide quite a show over a very long season.The flowers close at night and they like a bit of sunshine to encourage them to open up fully. We know how they feel! Sun. Any reasonable soil. 12 in. 2 litre pot.

We have grown Biscutella off and on over the years and we keep coming back to it, as it such a distinctive form of Sisyrinchium, with a charm all of its own.
There is another Sisyrinchium which rejoices in the varietal name Quaint and Queer and which is suggested by some to be the same plant by another name. However, although they look similar, we note that the RHS lists them separately, with Biscutella described as an accepted name and Quaint and Queer as a tentatively accepted name. Which leaves us none the wiser. We're sticking with the former.
Plant care is as easy as it gets. Trim off old flowering stems once they have gone over. We like to cut the foliage back a bit before winter sets in just to keep things nice and tidy. You can divide the clump every few years if you like.
Sisyrinchiums are native to the Americas and enjoy a range of habitats, from mountain slopes to meadowland, hence species names such as S. Californicum and S. Idahoense.
Sisyrinchium Biscutella is a hardy evergreen perennial with a clump of grass like leaves and buff purple streaked flowers in summer suitable for full sun.
