Help about your size

Swamp Milkweed (Asclepias incarnata) grows with ease in wet gardens since it normally grows in wet meadows, river bottoms, and swamps throughout the US. Clusters of small mauve-pink flowers bloom in the summer, each filled with pollen and rich nectar for pollinators. These flowers stand above long, lance-shaped leaves that are incredibly important for caterpillars! 

Milkweeds, including Swamp Milkweed, are essential for the Monarch lifecycle. Their relationship includes more than just swapping nectar for pollination. Caterpillars exclusively feed on their leaves, which are filled with cardenolides. Cardenolides are stored in the bodies of Monarch caterpillars and butterflies as a defense against predators. Without Milkweed, we wouldn't have Monarchs!

FAQs

Care & Planting Guide

After your plants have arrived:

The plants in this box have just spent a lot of time being jostled around in the dark and must be unboxed right away. Unpack the entire box, removing packaging material and plants. Remove any plastic covering the pot and/or soil surface and check if the soil is dry. Water anything that is dry or looks wilted. Any plants that have come unpotted during shipping can be replaced in their pots and their roots covered with soil.

Place plants in a cool, shaded spot out of direct sunlight for 24- 48 hours after unpacking them. This allows them a recovery and acclimation period before planting. If you must hold them longer, place them out of direct sunlight, wind, heat, and cold. Check daily for watering.

USDA Hardiness Zones

USDA Hardiness Zones Map

ZONE HARDINESS

The United States Department of Agriculture (USDA) has devised a system to provide gardeners with a basic guide to plant hardiness – how much winter cold a plant can withstand. The Hardiness Zone Map system divides the United States and Canada into numbered zones based on lowest average winter temperature. Even within a zone, different micro-climates exist, such as large urban areas which may be warmer or land situated at different elevations.

WHAT EFFECTS PLANT HARDINESS

The Hardiness Zone Map is a valuable tool but it is not foolproof. There are a variety of factors that can influence the hardiness of a given plant in a garden. These factors include: soil type, drainage, snow cover, exposure to wind, winter, rainfall (or lack of), as well as fluctuations in temperature.

Growing like a weed!! :D

My 2 milkweed plants arrived in great shape. I precisely followed the directions for resting/recovering and then planting them, and I swear they have doubled in size already! I can’t wait for the butterflies to find them, I think they will make some gorgeous insects. ❤️

Progress report

it dries out quickly. So try not to overwater, but give it enough is a challenge.

Failed

The swamp milkweed came with relatively good root systems, but the stems were non-existent making planting them properly very difficult. However, I marked each one so I could monitor them, but now there's nothing growing at all. Very disappointed.
