Description This elegant clump forming perennial is iris-like in appearance in that it produces a creamy multitude of pale yellow blooms; each is centered with a deep buttery colored eye. Also known as Yellow Eyed Grass, as well as Rush Lilly.

  Morphology:
Native to Chile, Satin Flower grows to a height of 2’ with an equal spread. The slender flowering stems arise from erect, evergreen clumps of spiky green-gray leaves that extend to 18 inches with the flowers held aloft.

Blooms appear from June through July. Note the back of each petal has a pronounced purple stripe—hence the species name of “striatum.”

  Adaptation:
Sisyrinchium striatum will grow throughout the state in light shade to full sun. All that is required is water. One plant will soon form a clump of new plants. In warm climates it can become a somewhat invasive plant. It will produce a prolific number of seeds, which can sprout and grow. Take care in planting this species near wet areas.

  Pests:
None reported.
