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.

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.”

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.
