I have read another account of early summer bloom in some plants,
including Immortality, Queen Dorothy and Baby Blessed . Rebloomn
in June and continuing to Fall. Plants were in an area where they got
light all night from a security light. It makes me wonder about all
other reports of June/July rebloom. What were the lighting
All three of these cultivars are, or were, in my front garden. I
that, in QUEEN DOROTHY's first year here, it bloomed in spring, again
July, then 3 more times until late fall. It has not repeated that
performance. In fact, it seldom reblooms at all, despite having been
in the garden more than once. The only major difference in conditions
then until now is that the county several years ago installed a
over my objections, about 50 yards down the street, so that the garden
longer is in full darkness at night. Might that have an effect? I do
know. BABY BLESSED rebloomed in most years, but IMMORTALITY does not
Here's another puzzler: HAUNTING reblooms reliably at Halloween here
7a), and does the same at Winterberry Gardens (zone 6b), despite the
that Winterberry's elevation is 1,000 feet higher than mine and its
spring bloom is 2 weeks later than mine. We are at the same latitude.
would seem to indicate that temperature is not the deciding factor as
HAUNTING is concerned.
