The message .com
from "Totty" contains these words:

I have grown this for the first time this year, from seed that was a
freeby with Gardens Monthly. It seems to like my hot, dry conditions,
and though drooping slightly at the end of the day, perks up overnight
without being watered more than once a week. Does anyone know at what
stage I will see the promised "blueing" of the vegetation and flowers?
At the moment the leaves and bracts are glaucus, but pale, green, and
the flowers are a pale salmony pink. Is the darkening dependent on age
or conditions?

Mine in Scotland are blue atm, so this may be something to do with
your warmer-than-UK climate. They set plenty of seed here, so be sure to
save some for next year. I find they do better if broadcast in Spring,
where I want them, rather than just left to self-sow

Janet.
