Big Blue Tree Collards are a 2020 introduction and extremely limited perennial tree collard. It is a naturally occurring garden hybrid from the Berkeley Farm that appears to be a cross between the Merritt Tree Collard, Dino Tree Collard, and maybe even Purple Tree Collard. Big Blue gets between 3 and 8 feet in height, and appears to naturally branch into a mid-sized shrub form. Within the first year or two, wide stalks 1-2 inches in diameter can 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 1 1/2 feet long and are a stunning blue-green color with a hint of pink/purple in the stems. They are crinkly like Dinosaur Tree Collards, but much wider and less linear.
Because it is a new introduction, at this time it’s cold hardiness or heat tolerance is unknown. Based on past experience, it should be at least as cold and heat tolerant as its parentage. One can expect it to be good in zones 8-11, and probably marginal in zones 7 a and b.
