Maintenance Tips
Asclepias fascicularis is a California native herbaceous perennial that is known for being a host plant to the Monarch butterfly. It can grow up to 3' tall and wide and is generally a rangy-looking shrub. It is rarely grown in a garden for its aesthetic value and is commonly planted to bring butterflies into the garden. Since it is a host plant, the butterflies will lay eggs on the plants, and the caterpillars will eat the leaves, often stripping the plant of all foliage and causing it to appear unsightly. Pruning is rarely necessary, as the caterpillar's appetites usually take care of maintaining the size of the plant. This is a drought-tolerant, sun-loving plant, so make sure to plant in full sun in well-drained soil to ensure its success.
