Can someone id this plant? I bought it at a plant fair and forgot the name of it. It grows very tall - my sister's plant is over 5' tall. It roots extremely easily just by laying a stalk down and covering it with dirt. I was told it was a form of spinach with edible leaves. Butterflies love the flowers.

Looks like a Celosia .... possibly C. argentea spicata: Wheatstraw Celosia (Celosia argentea 'Cramer's Amazon')

edited to add another link and correct my spelling.

That looks like it but the guy told us the leaves were edible and it was a form of spinach. Hmmmmmm.

C. argentea var. argentea is also called Lagos Spinach and the leaves are eaten as a vegetable. Maybe that's what he meant.

That's more like it! Thanks so much!
