This plant grows as a large shrub over six feet tall. It has red flowers and long thin thorns
this appears to be Erythrina crista-galli, the cockspur coral tree, native to South America. The only other one that I know that looks like this is Erythrina fusca – but I don’t think that is cultivated in the USA.
It is attractive to hummingbirds, which pollinate it.
