When not in bloom, blackberry lily looks like an iris, with beautiful foliage suitable for any garden. When in bloom, from a distance it looks more like a freesia. Blackberry lily thrives with plenty of sun, good drainage and little care. They aren't always long-lived, but their talent for self-seeding can keep them in a garden for decades. The seedpods that form after the plant has bloomed look the blackest, juiciest berries you ever saw, but they are only for not and not edible. In fact, the seeds are poisonous, so beware if you have pets and/or children.
