This page lists alphabetically genera or species from Co-Cy recommended for growing in shade by members of the PBS list, sometimes with comments, followed by the name and the location of the person who suggested them, usually from experience growing them. There are links for more information and if we have photos of these plants on the wiki, we have included a few photos to illustrate them on this page.
Codonopsis is a genus that prefers partial or mottled shade.
Colocasia esculata was suggested by Matthew Gale from Birmingham, United Kingdom to give a jungle feel to a garden. He used tubers from a local Chinese supermarket and found them hardier than expected. In Las Cruces, New Mexico, zone 7 and arid, this species was one of Boyce Tankersley’s favorites.
Convallaria majalis is often found in lists of bulbs that can be grown in the shade. It was recommended by someone who has grown it in partial shade in Iowa and Michigan and currently grows it Northern California. He reports that potted plants are easily forced into flower after vernalization at 0 to 2 °C for 12 to 14 weeks.

Corydalis nobilis is a lovely, statuesque tuberous corydalis with glaucous foliage and 2-3" heads of yellow flowers with a mahogany tip. Each head has about 10-25 flowers that are a little over an inch long. Comments from Ernie O’Byrne, Eugene Oregon.
Crinum moorei was a favorite of Patty Colville and Ann, Southern California, and was suggested by Jim Shields for greenhouses in colder climates.
