Blackberry lilies are lovely, low low-maintenance plants

 

I’d like to grow blackberry lilies in my new garden. When is the best time to plant them?

Seeds in late summer resemble blackberries.

Blackberry lilies (Iris domestica) are easy-to-grow plants that add an interesting touch to garden beds and borders. When the leaves emerge, they resemble bearded irises, growing in a fan shape. The six-petaled red-spotted yellow flowers bloom about mid-summer atop tall, slender stems. In late summer, the flowers give way to seed capsules that split open to reveal shiny black seed clusters that look like blackberries.

Blackberry lilies grow from tubers. Plant them in average, well-drained soil, about an inch deep, any time the ground is not frozen.

Clumps of blackberry lilies expand by creeping rhizomes, and the plants may also self-seed if growing conditions are right. Provide regular water as the plants grow and bloom.
