Gardeners' Notes:

Negative coriaceous On Mar 15, 2014, coriaceous from ROSLINDALE, MA wrote:

This shrub has gorgeous soft blue foliage, as inviting to the touch as some furry blue pet. It's a common plant here, because in the nursery it has great appeal to the eye (and the fingers).

Unfortunately, in many places, including here (Boston Z6a), the interior needles brown out progressively over a couple of years. A heavy load of dead needles accumulates, which when you clean it out, leaves blue tufts at the ends of scrawny naked branches. It's probably better to clean out dead needles more frequently, but it's time-consuming fiddly work that few people want to do.

Not a long-term landscape plant here. I suspect it isn't any better most places in North America outside the Pacific Northwest and maybe the Canadian Maritimes.

Neutral palmbob On Oct 30, 2008, palmbob from Acton, CA (Zone 8b) wrote:

One of the most commonly sold Chamaecyparis in southern California which seems odd to me as it is not rated for these zones (8b-10b)... and I am discovering why not... doesn't tolerate summer heat well. Still, some manage to grow it in containers or in shaded gardens successfully, so perhaps it should be raised up a zone or two? Has nice, soft needles and curled branchlets- definitely a 'user-friendly' plant in terms of comfort and safety. Has a nice blue color, too.
