Narrowleaf Milkweed Care and Growing Tips 

WHY MILKWEED IS IMPORTANT

During the most crucial stages of their life cycle, monarch butterflies depend on milkweed, their host plant. Because milkweed is poisonous, the monarch will only lay its eggs on this one plant. 

HOW TO GET MILKWEED SEEDS

ECOLIFE recently launched our Milkweed for Monarch program to create more monarch-friendly habitat across California.  

CARING FOR YOUR MILKWEED

Asclepias fascicularis, often known as Narrow-Leaf Milkweed, produces fragrant white or lavender blooms in the summer that give beauty to any garden. 

GERMINATION

Seeds are sown directly into the ground in fall or germinated indoors in spring. 

TIMELINE

Narrow-leaf Milkweed is perennial and dormant. Expect your milkweed to look lifeless in winter. Winter dormancy is complete for Narrow-leaf, unlike Tropical Milkweed. 

PESTICIDE CONCERNS

It is vitally important to refrain from using pesticides, herbicides, or insecticides on your milkweed plant.  

WATERING AND SPACING

California-bred narrow-leaf milkweed is drought-tolerant. Water your seeds or seedlings until they are established, then reduce watering to as needed.
