Abelia is a lovely shrub that blooms up here til first hard frost in November and then the Jasmine Nudiflorum does well on the north side of the house, blooming Dec til March. It is best to grow it under an overhang, here, for some protection against snow and hard freezing. Both a hit with hummy.
Also, Rosemary starts blooming in Dec too. The hummingbird likes all these and has been coming for them for the past few winters. Viburnum starts blooming soon but they have never taken to it and Pieris is holding it's blossoms for the warmer weather.
I see the Chaenomelle, Quince Japonica is also holding its pink buds tight til the time is right. Hummy likes that too, a lot.
I was kind of surprised when I saw one feed on the Monk's Hood I have growing in a pot as this plant is toxic, shade and late blooming here.
As I plan on moving soon I've been growing Salvias in pots and hanging baskets for the hummies to feed on.
Hot Lips and S. Elegans are faves as are the Agastaches.
Buddlea, yes. Sour Cherry tree flowers too tho that may be bug hunting?
Lantanas and Mimulus, the perennial kind.
Lobelia that is used in hanging baskets is visited by them and they really liked a pink shamrock I grew in a pot.
I used an old ladder and stacked it with flowers hummies like for pics. Lots of fun.
I'd rather use flowers too.
Loniceras of all sorts.
They try most things but these are all favoured in their seasonal turn around here.
OOps and of course, Columbines, so beautiful together. Penstemons.....aaah, Spring is just around the corner.
Purple Mallows that grow themselves....
There's lots to choose from so matching what they like with your growing conditions and watering capability will help sort things out in AZ! Nice. I am envious of all the hummy company you will have there.
