Sisyrinchium
(Olsynium) douglasii - by Anne

Sisyrinchium
douglasii grows in a
sheltered spot in my garden, it grows 20cm
high and it does not seed around. |
|

|
| I
grew it in a pot for the first year and
was able to split it in two when I planted
it out. It is in very gritty soil, to counteract
my heavy clay and it is in quite a damp
spot. It gets plenty of light at the
moment, but it would probably be
considered semi shade once the trees leaf
up. The first bud appeared two weeks ago.
The bud is darker than the open flower,
which lasts about ten days. The leaves
grow nice and upright and it disappears
below ground at some point in the summer,
didn't notice exactly when.

| Sisyrinchium
douglasii - now renamed Olsynium
douglasii - is a bulbous plant
native to western North America,
where it is a meadow plant. Its common
names are Grasswidows or Widowgrass,
Purple-eyed grass and satinflower.
Sisyrinchium
douglasii var. douglasii was
discovered near Celilo Falls on the
Columbia River in 1826 by David Douglas,
and is named for him.
|
| S.
douglasii and most of the South
American species have been moved to
become Olsynium (though they are
still described under Sisyrinchium
in the AGS Encyclopaedia (1994)). The
difference is mainly in Olsynium
having rush-like rather than grassy
leaves, and some differences in the
flower.
