Project Tree Collard introduced the Jolly Green Tree Collard Plant to the public in 2020. It is a naturally occurring garden hybrid that appears to be a cross between the Merritt Tree Collard and Purple Tree Collard. Jolly Green Tree Collard gets between 6 and 10 feet in height, and tends to naturally branch into a large multi-trunked shrub form. Once the tree collard reaches 2-3 feet in height, it would be best tied to a sturdy stake as it can be top heavy in storms and high winds. Leaves can get up to 2 feet long and are a bright to medium green color with lighter stems. They are smooth like annual collards, but much larger. It blooms in spring but still provides more leaf production through the blooming period than some other tree collards. In the cool season, Jolly Green Tree Collards can blush purple on the leaf stems and leaves and become sweeter in flavor.
Jolly Green Tree Collards are hardy in USDA zones 8-11 and probably marginal in zones 7A and 7B. Reports from customers indicate it has been hardy to 20 degrees without protection for 3-5 days.
These seeds will NOT be true to type (identical to the parent plant) due to cross-pollination with other brassicas on the farm. If you want to grow Jolly Green Tree Collards identical to the ones we sell, please purchase cuttings or rooted plants. (they are not always in stock since we don’t propagate or take cuttings while they are flowering).
This seed will likely produce vigorous, leafy brassica plants that are of interest to plant breeding enthusiasts. They flower at the same time as our other collards so they will produce some interesting crosses. These tree collard seedlings will be more climate adapted than the parent plants.

I can validate that all the collard seeds from Project Tree Collard have a very high germination rate. I believe I had 100% pop in 3 days under the grow light and could not believe my eyes. I purchased seeds for all the different varieties and they were all the same so do not double seed as it is not really necessary. They were planted in 1 part 1/4″ sifted compost, 1 Part sifted Peat moss and 1 part fine perlite with ~10% worm castings mixed in. Watered them in with Organic AG Pure Protein 15-0-0 which seems to really help with my germination rates as well, Hope this helps others who are interested in purchasing seeds. -Jay
