Milkweed tropical (Arcadia nr Baldwin-Stocker Sch)

Young milkweed plants available for adoption.

Monarch butterflies rely on milkweed for their life cycle -- this is tropical milkweed, not native milkweed.

The difference is that native milkweed dies back in autumn, while tropical milkweed flowers continuously. Which can disrupt the monarch butterfly's annual migration because a food source is still available in winter, and the butterfly remains here instead of migrating to Mexico.

The solution is to cut back the tropical milkweed in October, eliminating the food source and encouraging migration.

At least so say the "experts" and I have no reason to dispute.
