About Hirtella, Milkweed Seed, Milkweed Seed
Hirtella Asclepias, more commonly known as Hirtella Milkweed or sometimes grouped under Asclepias hirtella and Tall Green Milkweed, is a native prairie species historically found across the central United States in moist to moderately dry meadows, savannas, and open grasslands. It is recognized for its tall, slender stems topped with rounded clusters of pale green to yellow-green flowers that attract a wide variety of pollinators, including bees, butterflies, and monarch caterpillars.

Pests & Diseases
Milkweed may develop leaf spots, rust, powdery mildew, or viral mosaics. Minor spotting usually needs only sanitation, but persistent mottling, distortion, or stunting warrants whole-plant removal. Avoid moving symptomatic plants among pollinator gardens, thin dense colonies, and clean tools before collecting pods or propagating roots.
Milkweed can attract aphids, thrips, spider mites, Japanese beetles, and slugs. Scout flowers and new growth regularly, handpick when practical, and protect beneficial insects with targeted controls.

Its Role in the Native Ecosystem
Tall Green Milkweed provides flowers used especially by long-tongued bees and wasps. Like other appropriate native milkweeds, it also contributes foliage for monarch caterpillars. Its less conspicuous greenish blooms add ecological variety to a planting without relying on a large, brightly colored floral display.
