Brilliant stuff, Graham! Your Audax looks almost subdued, properly autumnal, beside that flamin' tree.
Here, we've done our two months of March, and lurched into July with a spring-ish transition of about 5 days. Temps are now in the high 20s/low 30s. The tulips, barely poking their green heads above ground a week-plus ago, are now in full bloom & in danger of getting scorched. Even the black flies are in danger of dying an early death 'cos of the heat. I've heard sympathy for the tulips (donated by the Dutch government -- during WWII, the Dutch government in exile lived in Ottawa) but none for the black flies.
Cheers, John
