HOW TO GROW
Sowing: In late fall, direct sow the swamp milkweed seeds for sale just below the surface. Germination will take place in the spring, after the last frost. When the seedlings appear, thin to the strongest plant; seedlings usually do not survive transplanting, since they resent any disturbance of their roots. For spring planting, mix the seeds with moist sand and refrigerate for 30 days before direct sowing.
Growing: Since this plant does not tolerate drought, watering may be necessary to keep the soil moist. The flowers attract bees and many butterflies, while repelling deer. Because competing weeds will damage the growth of this plant, keep them down to a minimum.
Harvesting: This makes a striking cut flower. Cut the stems long, choosing flowers that have just opened. Keep in mind that the milky sap is mildly toxic and can irritate the skin.
Seed Saving: After the plant finishes flowering, 3-4" narrow pods will form. Be sure to harvest the pods before they split and the silky fluff carries the seeds away on the wind. As soon as the seeds inside the pod ripen to their mature brown color, remove the pods and spread them out to dry. Split open the pods and take out the silky seed material. Remove the fluff from the seeds. Store the seeds in a cool, dry place.

Swamp Milkweed
Wow, so many seeds! After learning that Swamp Milkweed is sought after by Monarch butterflies who then lays highest number of eggs on this plant over other species. Another fact Swamp Milkweed tolerates heavy clay soils, which is a plus in Vt.
Great Source

Looks great
Prompt shipping and beautiful packaging wit complete germination info.
For the Butterflies
Super fast shipping. The flowers look so vibrant I knew I had to ordered them. I planted these seeds and was so happy that 1oz actually filled up a big space. I look forward to see these feed the bees, butterflies and whatever needs them.
Ordered 1 lb.
The seeds are thankfully without all of the milkweed fluff, properly prepared, delivered promptly and the gold foil package seals nicely. Sowed seeds and will see how they do.

I have not attempted to grow any of the seeds yet, so my first impression is of the packaging. It is amazingly helpful and covers all the information I need to successfully grow the seeds and plants. And it really looks good, too.
Delivery was fast and ease of use of the online store was good. You've got a repeat customer now.
