As far as wintertime garden goes, those are some really vibrant colors.
I personally really like the morning frost that comes on the flowers when it starts getting colder towards wintertime.
If it gets cold there in your region but doesn't snow, do you still get the cool morning frost or not ?
It gets to about zero Celcius, sometimes a little lower, sometimes but not often. Usually winter nights are 2-10C. We get frost and ice on things though when cold enough and it's actually snowed up in the hills occasionally but not like you'd have.
