I think some of the shade tolerant herbs might grow there. You could try thyme, oregano, and especially French tarragon if you can find it. Lemon balm is one I don’t use, but a friend grows it in quite a dim spot. I’m no expert, but I woulgive a couple a try. Lovely spot.

Some ferns might work well.

Orchids would be interesting, but I imagine they would be pretty high maintenance. Not sure I want to go there. A lot of the herbs seems to prefer partial shade, and I not sure how well they'd do in total shade. But I guess I could try. Thanks for the suggestions!

I have an orchid DH gave to me too many years ago to count. It sits on the edge of my bathtub. If it's lucky, I remember to water it every 2-3 weeks. It blooms reliably every winter. Every 6 months or so I wipe the dust off its leaves.

In other words, it is the farthest thing from picky - and it looks elegant. +1 for an orchid in your lovely window.

Parsley, thyme, oregano, mint and chives all do well in my shaded garden.

If like cilantro, that should do well there (and the seeds are considered "coriander").

orchid and snake plant sound like good options. I may pick a few choice herbs as well. Thanks, everyone!

My orchids are in a west-facing window and get full afternoon sun. They love it there!

I jut looked at the tags for some herbs I bought. As I suspected, every one of them is a sun lover. The tarragon I just got (54 cents clearance-already sale) requires full sun, or at least 6 hours of direct sun a day. They might survive in the shade but they're not going to thrive in full shade, unless you have a sun lamp.

My horticulturist neighbour dropped off a whole bunch of orchids a few weeks ago because he's moving across the country. He says just to water/fertilize them once a week.

English ivy in a decorative pot. I have several in low light conditions indoors and they do well.

What about a few succulents?

What a lovely space! In addition to the mentioned English Ivy & Snake Plant you could look into the following plants for low light: Parlor Palm, Chinese Evergreen, Japanese Sedge, Bromeliad. Perhaps one of these would work for you.

Maybe a fern. It's far too dark for any of the herbs mentioned. Even a shaded garden is brighter than an indoor window sill under an awning.
