Join this special Garden Club event to help create a beautiful Monarch Garden at Grant Park!
Western monarch populations declined by 86% from 2018 -2019 and are at critical risk of species extinction. Take action for these important pollinators in the San Diego River ecosystem by helping us plant Narrow leaf milkweed (Asclepias fascicularis) and other pollinator-friendly plants at this fun community event!
Planting Narrowleaf milkweed in San Diego is vital because:
- It is the monarch butterfly’s exclusive host plant, as caterpillars feed only on milkweed and females lay their eggs solely on these leaves, while its natural compounds provide essential nutrition and protection from predators.
- As a native, drought-tolerant plant that blooms in sync with local migration, unlike tropical milkweed which can disrupt it, Narrowleaf milkweed restores lost habitat, supports endangered Western monarchs, and provides rich nectar for butterflies, bees, and other pollinators.
You'll feel a sense of accomplishment knowing you're helping conserve vulnerable species like the Monarch Butterfly while creating a vibrant educational garden for students and the community in the heart of our city.
This is the first planting day to create this beautiful garden. If you'd like to help on the second planting day, sign up for the Mission Valley Garden Club on April 4th too!
A huge thank you to the Clinton Foundation for their generous grant to support this planting project!
