Rose Blush:
I don't know how anyone can live in California and not garden. I used to live in Santa Barbara, San Jose, and San Diego. Everywhere, you can garden all year round. Plant bare root roses on Christmas vacation. That black clay coastal soil--I remember it well! caliche. I realize you are further up in the Mountains. What an inspiring place to be. Roses love California. Have you ever toured the old missions? Last time I was there, the nuns have done a great job of saving the old roses that came from Spain back then.
