Title: Toxicity and invasiveness of Scarlet Wisteria
Answered by: Nan Hampton
QUESTION:
I recently purchased seeds for Scarlet Wisteria (Chinese rattlebox tree). I spoke to a neighbor about this and she warned me not to plant them as they were poisonous to hummingbirds. Can you clarify this for me? Also, is this a good species for planting in the Dallas area?ANSWER:
Scarlet wisteria or Chinese rattlebox tree (Sesbania punicea) is an invasive introduced species from South America, so for that reason alone Mr. Smarty Plants strongly urges you not to plant your seeds.Poisonous Plants of North Carolina says that the seeds are highly toxic and may be fatal if eaten. The Alabama Cooperative Extension System reports: "The seeds contain a saponin that is quite toxic to poultry, cattle, sheep, goats, and humans. As few as nine seeds per bird can be fatal." However, I could find no indication that the nectar is toxic to hummingbirds.
Mr. Smarty Plants recommends the following beautiful native hummingbird- and butterfly-attractant plants as substitutes for the scarlet wisteria:
Bignonia capreolata (crossvine)
Campsis radicans (trumpet creeper)
Asclepias tuberosa (butterfly milkweed)
Malvaviscus arboreus var. drummondii (wax mallow)
Lonicera sempervirens (trumpet honeysuckle)
