Purple Tree Collards

Pot, Ecos Selection-PTCO_E $18.20 Out of stock

Tree collards came to the U.S. during the the early years of slavery. It provided valuable nutrition and was probably the first perennial vegetable in the south. The plant was normally propagated from cuttings using stem cuttings. All the leaves were removed and then the stem or stalk was stuck into the soil. This is how it is still propagated today. 

We were extremely fortunate to get seeds and began a permanent polyhouse planting  as well as an outdoor planting to develop perennial northern versions.   This is how we grow them. This has allowed us to create hardier and more robust forms.  Tree collards are considered a perennial Brassica but if it hits much below 25 F the plant will unlikely survive the winter.  However with selection many of our plants have survived in our polyhouses without supplemental heat during the winter with lows reaching minus 17 F.  In our taste trials we did notice that even the hybrids tasted like a collard.  The flavor seems to hold true but the leaf shapes are different and they are considered a hybrid in many cases. 

The flavor of the leaves is very mild and just delicious to eat fresh or cooked. Gardeners in mild climates will find the plant reaching 4-6 ft. tall in one season which can be trimmed to look like a thick Scotch pine Christmas tree if you prune it vigorously.  Tree collard stems can be kept in your refrigerator crisper section and stored that way through winter. Just make sure to remove the leaves. Plants can be brought indoors during winter too and can be kept in a sort of a dormancy by putting them on a cool window sill. 

We offer seedlings from the Tree Collard Project and Ecos selections. These are mixed seedlings of very good parentage. 

  • Tree Collard Project - From the west coast these wonderful large leaf selections are easy to grow and very vigorous. SOLD OUT FOR 2021

  • Ecos   -From plants grown outdoors for the last 4 years with good resprouting  charcteristics after winter with both below ground and above ground stems. Each plant is unique genetically but it is uncertain how much cold they will take. The parent plants have taken minus 15F twice and minus 20 once. The areas they grow in are sometimes blanketed by snow which may help in their survival. Limited inventory for spring of 2021. Some rooted cuttings of 'Michigan' will be available later in the spring. 

No shipment to WA.
