Showy Milkweed displays an upright, clumping perennial growth habit, reaching up to 3 inches tall with a spread of approximately 2 inches. Showy Milkweed produces clusters of small, colorful flowers in shades of pink, orange, or yellow.

Leaf size: approximately 6 inches.

Asclepias speciosa requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Well-draining sandy loam with some organic matter. Good drainage is essential for Showy Milkweed to prevent waterlogging, which leads to root rot and fungal issues.

Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
