First, NOTHING is actually "deer proof,"
they've never touched my bleeding hearts, flowering tobacco, astilbe, columbine, foxglove, baptisia, or marigolds. If you are set on growing plants that the deer particularly like, you need to protect them with an enclosure of some sort.
Actually... I'm not sure that is correct.
There are lots of plants that are deadly poisonous, and others that affect perception which they will avoid.
Other plants have particular times when the deer eat them... Columbine for instance... After flowering and setting seed, the plant's foliage dies back and tender new leaves emerge... which the deer immediately consume... this kills the plant.
Something like brugmansia and datura affects the eyes... You can be sure they will avoid.
Buckeye shrubs will cause drunkenness, another plant to be avoided...
Lets not forget the deadly poisonous plants like oleander and Aconitum...
Unfortunately, I can't really think of much winter colour that would be safe... you could try flowering kale... which isn't their favourite... but it is edible... and hungry deer would eventually find it...
Again... a little research...
There are books and pdf available that tell about toxic plants, those seem like a good starting point.
Deer will avoid fuzzy plants... until they get hungry... they will avoid strong tasting herbs like oregano and mint, until they get hungry...
The more deer in an area... the hungrier they get... and ballsy.
I once saw a lady walk out into her garden banging a big spoon against a kettle... Bambi let her walk very close before slowly ambling off!
I've seen them jump uphill over a fence they couldn't see over or through!
Not easy to garden when you have herds.
