Q.Milkweed / Butterfly Weed in containers?
We’d love to attract monarchs and maybe other butterflies to our small urban rooftop garden. Can milkweed and butterfly weed be grown successfully in large containers? Also, there’s no wild milkweed in the neighborhood. Where can we obtain seeds?

Yes, you can, but make sure that this container is pretty tall. This grows a taproot that will need plenty of space. We do not recommend places to purchase, but we do recommend doing an Internet search. You will find many providers that will ship to just about anywhere. You might have some native plant nurseries nearby, they are growing in popularity.
