Milkweeds are the host plant for the beautiful Monarch butterfly. Queen butterflies will also use this for their larva. Over recent years the Monarch population has been in severe decline. Help welcome them into your butterfly garden with the purchase of theses seeds. Each seed package contains 10 seeds. If you purchase more than one package of seeds from our store, you only pay shipping once :0)
Name: Rose or Swamp Milkweed (Asclepias Incarnata)
Description: 4 to 6ft tall clumps of stalks with blade-like leaves and clusters of pink flowers at the end.
Ideal Zone: 3a to 8b
Sun: Full sun to part shade. Shielding from sun in the hottest parts of the day may be required in desert climates.
Soil Conditions: Will tolerate a wide variety of soil conditions, prefers wetlands. Can be planted at edges of ponds. Will tolerate mud or wet clay.
Water Requirement: Medium, but will tolerate some dry spells.
Growing Instructions: Cold stratification is necessary for proper germination. If planting in Spring, stratify by refrigeration 1-2 months prior to planting. Can be directly sown outdoors during fall/winter in warmer climates. Plant 2-3ft apart, ¼ to ½” below the soil surface. Can be planted directly in the ground or in pots or planters. If using a seed tray, move plants to final location when seedlings reach 2-3” tall to avoid binding roots.
Growing Notes: Under ideal conditions, these plants will produce many seeds and propagate easily. Put a rubber band around seed pods to prevent them from opening if you want the seeds for later use or pinch them off to prevent reseeding altogether. Stem cuttings will re-root in water or moist soil in warm weather.
In the Garden: A host plant for Monarch and Queen butterflies. Large numbers of caterpillars will strip the plants to bare stems, but the leaves grow back quickly and often with more vigor. All types of butterflies and hummingbirds will love the nectar produced by the flowers. The milky sap is a mild irritant, which makes the butterflies distasteful to predators. Can be prone to aphids, but this does not seem to damage the plant. Delicate, papery leaves dry out quickly so this variety requires more water than other milkweeds.
