Abelia, Anthony Waterer Spirea, Loropetalum-dwarf, Quince are just a few I can think of at this time of day.

Here is a link that might be useful: Propagating Perennials

Lantana, butterfly bush, rose of sharon, roses, salvias, vitex, camellias are a few.

Other colored azaleas?

I was thinking possibly Florida azalea and Weigela. I'm Spring bloom challenged myself. Do the red and yellow buckeyes bloom then?

My first thought was native azaleas, although deer will browse those. I have a deer resistant list somewhere in one of my notebooks.

I have a friend who has deer come right up to her house and eat nearly everything. She has been using milorganite with great success.

Not sure how deer resistant they are but I love the flame azaleas that are blooming now in the mountains!!

Here are a few suggestions - not all are deer proof, but deer resistant.

*Rockrose - likes good drainage and is blooming now
*Barberry - color and berries
*Caryopteris - Blue Mist Shrub
*Russian Sage - silver and blue
*Caryopteris divaricata ''Snow Fairy,
*Salvias
*Hydrangeas
*Beautyberry - purple or white berries
*Chastetree/vitex - - you can cut it back to keep it in shrub form
*Lindera/Spicebush -
*Summersweet/Clethra alnifolia - pink or white
*Spirea - summer blooming types
*Camellias - fall and spring bloomers

Not sure about the deer resistance of these.
Winter bloomers
Wintersweet
Winterhazel - Corylopsis spicata
Winterhoneysuckle

Baptisia, although they will probably bloom after the first plants that you listed.
Dianthus
Strawberry foxglove
Penstemon -- blooms with and after Baptisia
Salvias

Jessamine blooms at that time -- deer won't eat it. I don't know about beautybush (Kolkwitzia amabilis) and Weigela.
