Asclepias tuberosa


Butterflies are very attracted to asclepias, hence the common name. A vigorous, hardy, and rugged grower, plants are about two feet tall and can become invasive. The spiky leafed stem carries large bracts of dozens of red buds which turn orange as they open. It prefers full sun and a well-drained soil. An interesting and long lasting cut flower, the seed pod can also be useful as an everlasting. Also known as Pleurisy root.  40 seeds

Delivery was a little slower due to Covid-19, but your communication was great. Have had good luck with seeds..

Have loved Pinetree Garden for

Have loved Pinetree Garden for years. The seeds that I have used before all turned out really well. Never a problem. I use Pinetree Garden more than any other supplier and have always had a good experience. I am trying a few new varieties this year and expect that they will be as productive as the varieties that I have used in past. Keep doing whatver you are doing because I will need you in the future.

Winter Sown

I had good germination using the winter sown method - in gallon milk jugs set out at the end of February. This was the first time I've done seedlings this way. They are still too small to set out yet (end of April) but I will probably transplant them in a few weeks.

Butterfly ****

This is a great summer blooming plant in Oklahoma's hot summers. Germination was quite good as is always the case with seed from Pinetree.
