Narrowleaf Milkweed - Asclepias fascicularis
Narrowleaf Milkweed is a gorgeous California native flower that is the sole source of food for the Monarch butteries. The butterflies lay their eggs exclusively on Milkweed plants, creating an opportunity for us to plant Monarch habitat!
Grows as a subshrub about 2' - 4' high with stunning fragrant flowers. These wildflowers are easy to grow and propagate through rhizomes. Known for their beautiful colors ranging in greenish white to deep purple, the Milkweed brings joy and life to every garden! Exuding a delicious vanilla scent, the milkweed also attracts other pollinators while bloom from June - August.
Also known as Mexican Whorled milkweed, this milkweed grows well in dry climates and will blossom from June - September. This beautiful low maintenance, drought tolerant wildflower may be slow to grow the first year, as it sets its taproot deep into the earth. In following years, it will grow more vigorous.
It is very important to plant locally native milkweed species. Please learn which milkweeds are native to your region and consult this milkweed range maps from the Biota of North America Program’s (BONAP) North American Plant Atlas.
