I've had sea kale in my Seattle community garden plots for over 20 years. I started them from seed obtained from J.L. Hudson, Seedsman. I've seen plants offered by a few online nurseries, but do not remember which. My own plants have a wonderful coloration, with purplish stems and pale blue-green leaves. I've seen other specimens with no such colors, just an insipid pale green. Every spring one is treated to large, dense umbels of white&yellow
flowers which are strongly and deliciously scented of honey.

Oh, and the plants are edible. Tastes like cabbage.

Green leaves I would wonder about being Crambe cordifolia instead of C. maritima. But this has a different leaf shape and veining - if sea kale is sometimes green I just have never seen any indication of this myself. C. maritima being a crucifer it can have one or more pest problems like those of the more familiar cole crops. I think when I tried it I couldn't keep slugs off. Nevertheless, as I remember it I continue to see plants at independent garden centers here - I would make some phone calls to see if there are any around now or if there are any plans to get some later in the season.

OK, thanks. I was hoping not to have to seed or order, but I shall do so if I can't get a local nursery to help. About 10 years ago I asked Wells Medina to get some pineapple sage, which they did. I never go there anymore, but did this year I did...and there was pineapple sage. Must have turned out to be popular.

Embothrium, when I had a plot, I successfully kept slugs out of my cabbage by surrounding them with a *lot* of really rough-barked conifer twigs. They're all over my yard, so it was a natural. I kept one through the winter. Best cabbage ever.

Pineapple sage is a kind of standard item here.

Here is where? The woman at Wells had never heard of it when I asked for it, but this year it was out there with the standard stuff. I felt I'd started a Wells-trend. :-) It's a nice, easy plant. I like how it turns into an instant shrub.

I think he means here in the PNW :-) Salvia elegans (pineapple sage, tangerine sage, melon sage, fruit salad sage, etc) is pretty much a seasonal staple at most nurseries and garden centers around Puget Sound. 'Golden Delicious', a gold leafed cultivar, is very popular. Folks buy it to flavor ice teas, lemonade and cocktails and fruit salads and to tempt hummingbirds. With a bit of luck and excellent drainage, it can winter over.

I believe I remember seeing it at the annual Seattle Tilth sale.

Not in the Seattle area, I'm on Vancouver Island and growing Sea Kale for the first time. The only place I found online selling sea kale plants is' Food Forrest Farm' and they are out of stock until this fall. I'm growing from seed from Restoration Seeds bought this spring and after reading they can be difficult to germinate I was delighted to see 12 of the 15 seeds did. So if you can't find plants anywhere I had good luck with seed from Restoration Seeds.
Not the best picture, sea kale and skirret seeded this spring. sea kale on the left, kind of floppy looking but apparently this is just the nature of the beast :).

The Plant Locator - Western Region source book that Black-Eyed Susans/Timber (Portland) put out in 2004 listed 2 Oregon suppliers, 1 in Washington and 1 in California for Crambe maritima. (Also Heronswood was indicated as having one type being called C. maritima Purple Blush form).

Same publication gave 14 sources for Salvia elegans (and 4 for S. elegans 'Scarlet Pineapple').
