Growing Information
Growing Silky Formula Mix Asclepias
‘Silky Formula Mix’ is an open-pollinated asclepias blend prized for its large flower clusters, warm color range, and exceptional pollinator appeal. Blooms appear in vivid shades of scarlet, gold, and deep red, creating a brilliant display while attracting butterflies, bees, and other visiting pollinators.
Plant ‘Silky Formula Mix’ seeds about ¼ inch deep and space plants 12 to 18 inches apart. Grow in full sun. Germination typically takes 14 to 30 days after stratification.
Ready to bloom in about 110 days, enjoy the flowers as they open and reach their best display stage. Plants provide color from June until frost, and the large flower clusters also make striking stems for cutting.
Bright, pollinator friendly, and long blooming, ‘Silky Formula Mix’ is an excellent choice for ornamental beds, pollinator gardens, cut flower plantings, and sunny mixed borders.
