Carmine Rose Butterfly Flower
Asclepias incarnata. This is a must have for the butterfly garden! Commonly called Milkweed, it is the exclusive diet of the Monarch caterpillar. We have, in fact, seen several such caterpillars in our field trials! An impressive late summer flowering border perennial. Flowers the first year. Carmine Rose has beautiful rose coloured flowers. Start seed indoors 8-10 weeks before last frost date. Reaches a height of 40 inches by second year. Approximately 200 seeds/pkg. Zones 3-8.
Start inside 8-10 weeks before planting out, in peat pots. Cover seed lightly, provide light and cool conditions (10-24 degrees C). May also be direct seeded outside in early spring or early autumn. Transplant when plants are still small in early spring. Space 24 inches in a permanent spot.
These plants hate to be moved or divided. Full sun to light shade and soil. Pinch back plants when 6 inches tall to encourage branching.
