Blackberry Lily Seed Pack
Blackberry Lily: Iris domestica
Iris domestica is native to North America. Its common name, blackberry lily, comes from the seed pods which form after flowering; as they open, they display black seed clusters reminiscent of blackberries. The seeds are not edible.
Blackberry lily is an herbaceous perennial. It starts to bloom in mid-summer and continues until early fall, producing striking orange flowers covered with red dots atop sword-like foliage. After flowering, the 2-3' tall plants will set their seed pods.
Start seeds inside 10-14 weeks before the last frost date. To encourage germination, place the seeds in a plastic bag with moist, but not wet, growing medium and place in the refrigerator for 1 week. After 1 week, remove the seeds and plant into seed trays covering the seeds with ¼" of planting mix. Seeds germinate in 3-8 weeks at a soil temperature of 70°F. When the plants are well established, divide the rhizomes every 3-4 years in the spring. USDA Zones 5-10.
