I winter-sowed these in early March in plastic bottles outside. They germinated/grew easily once spring arrived and were repotted into a bigger pot. Did really well for a couple of months, until I probably forgot to water them for a few days. Alas, butterflies could not get much nectar from brown sticks. I planted them all in the ground in fall, hoping the roots somehow survived below the brown sticks.

Do the opposite of what I did, and you will have great success.
(I thought butterfly weed seeds need cold stratification, which is why I winter sowed them.)

Haven’t planted yet but will here soon.

I have enjoyed all the seeds I have purchased from you. Already good results.
