Oh, Reg--forgot to say that Cardinal-flowers are in the
Lobelia family.
Lobelia cardinalis
I also have some Great Lobelia (
Lobelia siphilitica) blooming nearby that happens to be more of a bluish color:
Hummingbirds like them both. Bot are native plants in this area, which in part explains why I can grow them (they need no close attention from me, therefore are more likely to survive my green, but moldy, thumb
)
Not sure if the cardinal-flowers have another name. I've seen it as Cardinal Flower or Cardinal Plant, too, but always with Cardinal as part of the name.
