Description
Purple Tree Collard x Daubenton perennial kale ‘Keeper’ a very special perennial brassica with purple/green tender leaves and a bushy habit, reaches a height and width of about 1.5m. We have had it growing for four years and it hasn’t flowered so far. This came to us as a gift from plant breeder Graham. D. Jenkins-Belohorska. Named ‘keeper’ as it was the best of a bunch of perennial kale/collard crosses. Once mature, leaves can be harvested all year round. Plants can go on producing for 5 – 8 years or more and are hardy down to about -10c. Price is for one unrooted stem cutting. Stem cuttings are thick stems with a growing tip that need to be potted up in deep pots of compost. They will root easily within 4-6 weeks, full instructions given. Once your cutting has rooted it can be planted out. When it has matured into a nice bushy plant, you will be able to take cuttings yourself and endlessly propagate new plants, providing yourself with leafy greens for many years to come.
How to root a stem cutting
Full instructions are sent with your order, rooting stem cuttings is really easy to do. A stem cutting is a thick section of stem from a mature plant with a growing tip. Place your stem cutting in a deep pot of compost with the growing tip above the surface and the stem below the surface. Make sure there is enough room for roots to form in the pot, you can always trim the stem a little if you need to. Some people like to use an organic rooting hormone, but this is not essential. You can also place a ventilated clear plastic bag over your cutting to help it root faster. After 4-6 weeks you should see a bit of new growth on the cutting and start to see white roots emerging from the bottom of the pot. Let your plant get to a good size before planting out with about 6 true leaves. You can pot it on one more time if you wish to get it to a really large size before planting out.
Propagating more plants
Once your plant has established and has nice bushy growth, you will start to see side stems with ridges. These can be used to make your own stem cuttings and you can endlessly propagate all of your future plants yourself.
Pests & diseases
After a year or two they should be large enough to survive without any protection. We don’t use any crop covers with ours and although purple tree collards can be attacked by cabbage whites, even the most well nibbled plants bounce back completely by autumn. We have also found that interspersed plantings of perennial brassicas make great companions – greatly reducing the damage to regular brassica crops by acting as pest beacons, whilst having the innate capacity to survive them.
Harvest & eating
Let your plant get to a good size before you start harvesting. Once mature you can harvest leaves all year round. Use in the same way as any kale. It has the most delicious nutty taste and surprisingly tender considering the size of the plants.
