Want to support Monarch Butterflies in your own garden? Here are some resources!
1: The only plant Monarch caterpillars eat is milkweed. Learn why planting native milkweed is best and why tropical milkweed creates serious concerns for monarchs.
Here is an excerpt from a Los Angeles Times Article that explains it well:
“Monarch caterpillars eat only one plant — milkweed — and many Californians have planted the showy tropical milkweed (Asclepias curassavica) to help. Indeed, most SoCal nurseries offer only tropical milkweed, a handsome non-native plant with feathery purplish-green leaves and deep orange flowers.
But well-meaning gardeners who plant this kind of milkweed are actually harming, not helping.
The problem is that tropical milkweed doesn’t die back during the winter in temperate climates like Southern California’s, according to the Xerces Society for Invertebrate Conservation. That permits protozoa parasites (Ophryocystis elektroscirrha, or OE) to multiply on the plants, which are eaten by the caterpillars when they hatch.
When the caterpillars consume too many OE parasites, scientists believe it sickens and weakens adult monarchs, messing up their migration patterns, mating success, flight ability and lifespan. And having milkweed that blooms through the winter also disrupts the butterfly’s migration patterns, experts say.
In other words, those evergreen tropical milkweed do more harm than good in Southern California, says Ron Vanderhoff, general manager of Roger’s Gardens nursery in Corona del Mar. That’s why the nursery stopped selling tropical milkweed a couple of years ago.”
The Xerces Society has an excellent article on why planting native milkweed is best, what kinds we have here in California, how to plant them and when: https://xerces.org/sites/default/files/publications/19-004.pdf
2: What do Native California milkweeds look like? What kinds are there?
There are fifteen species of milkweed native to California, but the two most easy to find for purchase are Showy Milkweed (Asclepias speciosa) and Narrow Leaf Milkweed (A. fascicularis). Both die back in late fall (around November) which signals to the migrating Monarchs that it is time to migrate, but create vigorous underground root systems and will pop up again in Spring, usually around mid-March or early April. March/April is also the best time to plant from seed. Of the these two types, Narrow Leaf is a bit easier to get established in our SoCal region. While slow to establish, a few years in you will begin to see your milkweed colony grow!
3: Here are places you can buy California Native Milkweed (starting mid-April) & California Native Plants year round.
