Sisyrinchium striatum

Sisyrinchium striatum flowering in my garden.

Sisyrinchium striatum is a member of the Iris family from Argentina and Chile. Therefore it is climatised to hot and dry; sun or shade; and cold frosty winters. However, from my experience it is best to grow in full sun and on the dry side as they are prone to rot and fungal disease. It is a low maintenance plant that only requires the whole clump to be cut back after flowering (as you would with an iris). I recommend you grow this plant in a place where it will get lots of air flow. At the end of summer you will notice some the leaves will be black at the base. This is due to fungal disease. Remove this leaves and bin them. My strain is more resistant to this however, I still need to remove some leaves each year. I also keep my plant "open" to allow for more air flow.

Sisyrinchium striatum is a semi-evergreen perennial that makes impressive clumps of upright blue-green sword shaped leaves. Soft lemon-yellow flowers are freely produced on strongly vertical stems during late spring and summer. Grow to a height of 70cm.

Excellent cut flower. The flowers close at night and reopen in the sun, even in a vase, so they're best cut and arranged in the morning.

Sow seeds during autumn, place seeds on top of the soil and don't cover them as they need light to germinate. Or you can direct sow the seeds. Keep seeds damp but not wet. Seeds will germinate when temperatures are around 20cm. Grow plants to around 10cm in height, harden off and plant out.
