I wasn't crazy about this color when I started looking for accent items for our capsule wardrobe, but when I started putting it against the neutral colors it really began to grow on me. And I'm also beginning to see the value in an accent cardigan. I think it's easy to assume that an accent color for a season or two might be best purchased in a blouse, tee shirt or sweater, but upon reflection I can see that a cardigan could be worn more often, and make more of a visible impact... Food for thought.
While I was combing the internet for this color, I noticed that the brand Schumacher had a variety of garments in this color currently available. It's not uncommon for a brand or designer to do a grouping in a single color; if Linden is really your thing, it's worth checking out Schumacher for some ideas.
Update: the way your monitor shows colors seems to make ALL the difference on this post. I was just at Belovedest's mother's home, and on her computer, this color looks like bile. Spinach baby food. Kind of grotesquely repulsive. On my computer, it's a subtle celadon green with undertones of grey or taupe. The difference is sufficiently startling that I now understand the wide divergence of all of your comments!
