This photo was taken on St. Patrick’s Day, the day this year which, at my latitude, happens to also be the equinox, or day when we have equal day and night lengths.
The actual equinox is 2 days later (St. Joseph’s Day this year, and about as early as it can fall).
Nevertheless, in my state, it’s snowing, it’s predicted to snow again on the equinox and it can snow well into May.
This is what my old-fashioned hydrangea macrophylla ‘Nikko Blue’ looks like right now. It’s been very warm, despite the late season snow nuisance. In fact, by the weekend, it will rocket up to 70 degrees, before falling back to something more seasonable.
But the warmth, and then the snow on top of the emerging buds, kills the flowers off of these old-fashioned hydrangeas every year.
Newer varieties, or varieties that bloom on new wood, are not killed by late freezes. Luckily I grow both kinds in my yard.
