I received a clump of this Cowslip Primrose from a gardening friend who lives 90 minutes away. She grows her patch in Lancaster County, PA. I think of her fondly each time I see it.

The brilliant red-orange color is dramatic in spring. The foliage is bright green and crinkly, rather dense, under 8" tall. Height is similar to my patch of Primula japonica, 12 - 15" when in bloom.

I divided the P.veris patch immediately after blooming and it pouted awhile in its natural summer dormancy but regained strength. None died. Now I have two robust patches, each one located in half sun. The clue for ID is the very long and dominant calyx, the tube holding the blossom.

Garden origin.

Has deep green, wrinkled leaves with toothed or scalloped edges and a pale mid rib. Bears slightly pendant, brick red to orange flowers slightly larger than the normal P. veris.

Can be found flowering in spring to early summer.

Likes a well drained, moist, fertile soil in full sun or light shade. Will self sow where happy but will also cross with practically every other Primula species in the vicinity so collected seed may not always come true, but you might just have some interesting seedlings pop up.

These are believed to be garden hybrids of P. veris with Polyanthus and/or Primrose types of Primula as they aren't found in the wild.
