Asclepias tuberosa L. (butterfly weed) is considered poisonous in that it has potential toxic cardiac glycoside and resinoid effects dependent on the amount consumed. All depends on if the risk is worth it to you.

Google pulls them up on several poisonous plant lists if you search by botanical name.

I am familiar with butterfly weed, it is poisonous. It's a shorter orange perennial that often grows wild in meadows. I am talking about Buddleia Davidii (butterfly bush). It's more of a bush with white, pink, or purple plume shaped blossoms, similar to lilacs. Thanks though.

PFAF is usually pretty good at telling you if a plant is, or ever has been, used for food. It seems that Buddleja has not. On the other hand it is not listed as poisonous either.

Using botanical names is useful to avoid confusion when seeking information about a plant, especially since common names are not the same everywhere.

Here is a link that might be useful: Buddleja info.

Buddleia Davidii is listed as "assumed safe" but "ingestion as teas, herbs, or medicines" is not recommended on U of CA Safe and Poisonous Plants website.
