Flowering unseasonably?

[ChrisB]

This, I hope, is Polemonium brandegii, it has just come into flower from seed sown 2016. Is this the right time of year for it?  I thought polemoniums flowered in mid-late spring?

Polemonium pauciflorum flowers from July onwards here.......

[ChrisB]

True Maggi, it is summer flowering.  It's just that I saw this sp on the show bench at Easter a couple of years ago....

[Maggi Young]

Hmmm, brought on early by being grown under glass, perhaps?

[ChrisB]

Probably, but still a big gap.... in time.  Wondering if any of our US people knows when it flowers in the wild....

I have had it flowering in mid summer and also in fall. It flowers later than Polemonium caeruleum anyway.

Extracted from "Alpine Plants of North America" by Graham Nicholls (Timber Press-2002)

""Polemonium brandegei ranges from Wyoming to Colorado, Utah and New Mexico. It is occasionally mistaken for P. viscosum, although it has longer, more upward-facing blooms. Flower colour varies from white to straw- or golden yellow. Jim Archibald found a lovely , snowy-white form in the Laramie mountains of Wyoming as well as a colony with golden-yellow flowers near Albuquerque, New Mexico. Although this species makes a lovely alpine house specimen, it can be short-lived. It is not grown very often, probably because seed is difficult to obtain""

And from Kenton Seth - speaker at the SRGC Summer event this coming Saturday - it was in flower the other week when he was in the mountains, though depending on site and season it might flower a bit earlier.

Hi Chris,
you look like you've got a good form of it too!
I hope that you are able to save seeds for the Seedex
cheers
