Tami,
I've never planted them with brugmansias. Not sure what kind of fertilizer you use on them.
Maybe someone else can chime in that more experience growing them together.
Call me to place your order if you can. If I know how many bulbs I'm shipping and where they are going to, I'll try to discount the S&H from what the website would normally charge you.
I've got some really nice bulbs this year!! A couple(White Queen and Gingerland) are in real short supply this year.
I will be Sold Out of them real soon!!!
