Milkweed (Asclepias species) is essential for monarch butterflies and a beautiful addition to any native garden.
Why Grow Milkweed?
Milkweed is the only host plant for monarch butterfly caterpillars. Without it, monarchs cannot complete their life cycle. By planting milkweed, you're directly supporting monarch conservation.
But milkweed isn't just for monarchs! It also:
- Attracts a wide variety of pollinators
- Provides nectar for bees, butterflies, and hummingbirds
- Adds beautiful blooms to your garden
- Requires minimal maintenance once established

- Tolerates a variety of conditions
- Spreads by rhizomes
Showy Milkweed (Asclepias speciosa)
- Large, fragrant pink flowers
- Excellent for larger gardens
- Attracts the most pollinators
Desert Milkweed (Asclepias erosa)

Important Note
Avoid tropical milkweed (Asclepias curassavica) in California. It doesn't die back in winter and can harbor parasites that harm monarchs.
When to Plant
Fall or early spring is ideal. This gives plants time to establish before summer heat.
