Like a velvet star unfolding in the garden, Verrone’s Obsidian brings deep chocolate-burgundy petals so dark they appear almost black. Its slender, sculptural orchid-form blooms create a striking contrast beside blush, ivory and jewel-toned flowers, lending a beautifully unexpected note to a gathered bouquet.

Planting & care
Plant outdoors after the last frost when the soil has warmed. Choose fertile, well-drained soil in full sun. Avoid soggy conditions; water regularly once growth is established. Add support as needed and remove spent flowers to encourage continued blooming. In cold climates, lift tubers after frost and store in a cool, dry, frost-free place for winter.
