I seen a few scientific articles that ruby throated hummingbirds are attracted to Gold Band big time.......and with that being an oriental species............you wander what attracts them........maybe the size of the flower or the scent and for sure not the color..........
I would think that the species put out lots of nectar.......maybe even more then some other types of lilies
maybe Lorn or someone knows for sure more about this then me
I have just a simple red
Asiatic out here blooming and saw 4 hummers around them this morning........showed no interest in the yellow ones close by
might have a lower amount of hummers around once the tulip tree is done for this year..............
