Mexican Whorled Milkweed
A most elegant and pleasing Milkweed species, the Mexican Whorled Milkweed (Asclepias fascicularis) grows throughout the West Coast and is the single most important species for Monarch butterflies in California. Stems are thinner and leaves more fine than many milkweed species, and the flowers show up as delightful small orbs of soft lavender pink. A favorite nectar source for pollinators and an essential plant for Monarchs! Be ready for them to eat your plants if you plant this one, but you’ll be rewarded with the sight of Monarchs in your garden!
