One other thing brassicas are known for is their bitter tasteĬollard greens have a characteristic bitter taste similar to kale. Tree collard on the other hand rarely go to seed, and therefore you might to cultivate them using cuttings and not seeds. Collard greens produce seed and flowers in the second growing season and they are cultivated by seeds. Tree collards are perennials and they can keep producing leaves for three to five years continuously CultivationĬollard greens and tree collards are cultivated very much differently. Life cycleĬollard greens are actually biennials but are cultivated as annuals, the plants produce leaves in one growing season after which the plant produces flower and seed n the second growing season. However, tree collard usually has some purple colored leaves on their stems. It doesn’t produce a central head like a cabbage while the leaves are arranged in a rosette. The arrangement of their leaves is similar as well. The leaves of tree collards and collards are quite alike in appearance, The leaves of tree collards grow large as collard greens. Tree collard might have to be pruned so that they could remain at an accessible height. This massive height difference between collard greens and tree collards could sometimes make harvesting from tree collard difficult. Tree collards have exceptionally tall stems, some been reported to reach heights of up to 20 feet. Perhaps the most obvious difference between these two plants is the massive difference in their height.Ĭollard greens have shorter stems, their height can reach about 2 feet and may be composed mostly of the thick broad leaves of their plants. These are the differences that I found between these two cultivars. Differences between tree collards and collard greensĭifferences between tree collards and collard greens. I had to do some research into these two cultivars of Brassica oleracae to find out how they are both different. Tree collards are also another cultivar of Brassica oleracae belonging to the acephala group, but unlike collard greens, tree collards are grown as perennials.Īlthough tree collards have thick leaves like collard greens, tree collards have a long stem which sets them apart. It is a biennial plants which is often cultivated as an annual for its thick leaves.Ĭollards or collard greens as they are sometimes known belongs to the acephala group of Brassica oleracae. However, within this same species are several cultivars which are perennials with very interesting properties different from other cultivars of this specie.Ĭollards is one of the many cultivars of the Brassica oleracae that we are familiar with. Many of the cultivars of these species that you might already be familiar with are biennials. They are also obtained by selectively breeding for particular properties, or by cross breeding already existing cultivars of this same specie. Many more cultivars of this single specie apart from the ones listed above also exists. These vegetables are different cultivars of single specie known as ‘ Brassica oleracea,’ and they all originate from wild cabbages that have been bred selectively over many years. It is interesting how popular vegetables like cabbages, broccoli, kale, collard greens and Brussels sprouts are more closely related than you would initially think that they are.
