Shaved, in view of recent comments over on discussions.....I suggest that you should update your my page details. 50F min. might be fine where you live but what happens during the day with a nice warm gulf stream flowing nearby.
Sure, I know where you live but that is only by reading past posts

I would guess that one to have quite a bit of equestris in it, nice growing. Looks like it could be a cross of equestris and violacea? Does it have a fragrance?

Sometimes I forget to add the zone.

I do not think it is fragrant. Thanks for the guesses on bloodlines..
We in Martin County are the last along the coast to have sub-tropical climate due to the gulf stream. It is about a mile off shore from palm Beach and all points south. But it veers to the east as it comes north to martin county. Which means a narrow strip along the coast in Martin is sub-tropical like Palm beach and south that goes several miles inland.. My mental marker for sub-tropics is coconut trees. Got a few in my backyard...

Mostly the Gulfstream keeps us a little cooler in the summer and warmer in the winter. That is with the prevailing southeastern breezes. But we do get west winds and everything changes for the bad. But fortunately the west winds are not that often...

It snowed in Miami in 1977...

I have a straight Phael equestris that looks just like it. Very nice.
