Hello Elaine -- so nice of you to visit and comment. I must say I'm jealous of your beautiful blooming hebe. Mine is a pink one and is often in bud, but the blooms are very brief, if at all. Maybe it's just not mature enough yet.
I love hebes despite their tenderness. We lost several in the last Winter too. Now is a good time to take cuttings so you could increase your stock for free.
