Yes, the three-year-old Primula vialii seedling in the peat bed did produce its first flowers this summer. Here are several pictures (too many), and then some of the other July Primroses — P japonica, P alpicola, the last of the P sieboldii, and Dodecatheon dentatum — and then a few Primula seedlings flowering out of season.
Primula vialii is a small plant in my garden. The tallest leaf is no more than 12 cm.
The flower head, when it first appears, is tiny and pale.
As the stem lengthens, the calyces expand and colour deepens.
Now high above the leaves, light purple flowers emerge from the red calyces.
In the same bed (cool, moist, lightly shaded), the Primula japonica, much increased over last year (their first), are large enough now to produce multiple tiers of blossoms.
My first Primula alpicola, its fourth year in flower, is now a large plant. When I divide it this fall, I’ll replant it nearer the front of the bed. Alpicolas should be grown where their fragrance can be appreciated.
This year, some new plants bloomed: lighter blue, violet, pale yellow, and pink.
A few of the Primula sieboldii continued blooming into July.
This white shooting star, Dodecatheon dentatum, looks something like a small hosta. It might flower better if its life were a little less easy. I may divide it and try it in the rock garden.
My nursery-raised Primula rusbyi bloom in alternate years. This was an off year. I now have several seed-grown P rusbyi, as well. This one was planted in the alpine pan last fall. P rusbyi are spring bloomers, but this seedling reached flowering size in late summer. Next year, it should have its flowers in May or June.
Another late-blooming seedling, a little Primula spectabilis in the alpine bed.
These hybrid Primula acaulis seedlings are flowering not only out of season, but only 6 or 7 months from sowing. Primrose seedlings normally have their first flowering after their first winter. Will these ones be hardy enough to survive a zone 3 winter?
