[SHADEGARDENS] Lobelia & hummers

Having spent an afternoon watching hummingbirds returning again and again
to a red plastic flower, I can't believe that pollen is the answer. There
is no pollen in the feeders, and they certainly get sugar solutions from
them. I think they are very sensitive to color. Possibly they are aware of
differences we don't see.

>A second question....have any of you noticed that Lobelia 'Queen Victoria'
>is not attractive to hummingbirds? Last summer, I watched the hummers go
>from one Lobelia cardinalis to another (they've also reseeded in the shade),
>and completely ignore the larger flowers of QV. This happened over and
>over...which makes me think that it must be pollenless....never thought to
look.
