Gardeners' Notes:


On Feb 26, 2014, coriaceous from ROSLINDALE, MA wrote:

Like the species, this is a great garden perennial. This form differs from the species in its softer flower color and its lower height---it's only 6-8" tall.

Armitage says it's hardy to Z3.

Like other forms of this species, it has a major burst of bloom in June with scattered rebloom the rest of the summer, pausing during heat waves. There's a second, lesser burst of bloom in September.

When I tried mixing this with the species, the species quickly crowded it out.

This form is not a cultivar, but a population from the island of Walney off the coast of Cumbria, England. It has received the coveted Award of Garden Merit of the (British) Royal Horticultural Society.

This plant is a great filler for gardens. Mine has reseeded itself prodigiously all through my garden. My husband refers to it as a weed.


On Jun 23, 2005, northgrass from West Chazy, NY (Zone 4b) wrote:

This plant is a low grower, does spread nicely making a satisfactory groundcover. It is covered with numerous pale pink blossoms from mid June to early July here in the north country. It does however gets a little ratty looking in late summer, in which case a good shearing can do it good.

Origin: Europe - This bushy low growing perennial comes from the rocky and sandy soils throughout much of southern Europe into Turkey where it forms tight 1 to 1 foot tall mounds of 2-4 inch wide leaves. Flowering commences in late spring and continues through summer. It will often reseed in the garden.
