You're welcome, Daphne. There's also an upside to the 10a zone - our rebloomers are often multiple rebloomers - Rosalie Figge blooms the most - usually 4 times a year, and St Petersburg 3 times, often including a January show. It always brings a smile to my face to see irises in the middle of winter!
(We do have a drip irrigation system for them.)
