Gardeners' Notes:

This is a beautiful little evergreen shrub to 2', quite showy in flower. I've often seen it in the wild. Foliage is distinctly bluish.

It's been heavily promoted by the nursery industry here in New England, because it's easy to propagate and produce, and garden centers can't keep them on the shelf when they're in flower. But it rarely lasts long here under ordinary garden conditions.

It's native to the northern US and Canada, as well as northern Europe and Asia. But it grows in cold acid bogs. If you have a cold acid bog, I highly recommend it. I haven't been able to keep it looking good in the garden. Plants deteriorate over time, under ordinary garden conditions here. Boston Z6a

Bought dwarf variety 'Nana' this spring at Lowes - way out of its native region here in hot-summered Sacramento. Planted under two 60' tall redwoods in a shade garden among hellebores and hostas, watered by sprinkler system. It appears to love it here and has doubled in size. The blue gray, almost icy looking leaves are dramatic color in the area of greens and browns. Can't wait to see it mature!

I planted 3 small (6" pot) bog rosemary plants in the moist rock section of one of my gardens in 1998. I've been very patient with these as they were browsed the second winter quite badly by deer. This year (04) is the first year that they've finally grown and filled in as I had planned way back when. The show they put on this spring was worth the wait. I've now learned to cover them with netting - and if we have a good snow cover, we don't have a problem.

Other than protecting them against deer in winter, they need no other care. They are planted in a moist to wet area, receive morning sun but are shaded from the hot afternoon sun. They seem quite happy.

A small evergreen shrub from Northern Europe.

Has leathery, dark green, oblong - linear, alternate leaves. Bears urn shaped, pale pink or white flowers borne in umbels of 2-5 flowers.

Flowers March - May

Needs moist, acid, humus rich soil in full sun or partial shade. In areas where the summer temperatures soar it will need to be placed in a cool, shady spot. Very hardy little shrub, great for acid, damp woodland gardens.
