I planted a couple of years ago seeds from the Real Seed Company called Tree Cabbage, a perennial plant.
This is what they say on their website: http://www.realseeds.co.uk/cabbage.html
‘This unusual Spanish heirloom has absolutely enormous leaves – and it looks like a Kale rather than a cabbage; it makes no head, just a tall stalk with a loose head on top. You simply take the huge leaves a few at a time to eat all year round. You can even keep it going for two years or more! Just cut it back when it tries to flower – it makes new growth, ideal for fresh cabbage in spring during the ‘hungry gap’. You can use it as cooked greens just as normal. But Tree Cabbage like this is also a key ingredient in the classic Spanish dish ‘Caldo Gallego’ – which is a delicious leaf, bean, and meat stew. Grows like cabbage, harvested like a kale . Very, very rare. Can be a short-lived perennial vegetable if the flowers are removed as they form.’
This grew really well for us in our dry sandy soil. Great germination and surviving results. It is harvestable throughout the hungry gap, just what you need in England when you might struggle to keep your greens going. It tastes just like kale.
But even better, the poultry love it. We pick a bunch of it every chance we get to go the the garden and drop it off in their run and they completely destroy it within minutes. Very nutritious for them!
Every time you pick the leaves, more grow. One or two plants could easily feed a family – we’ve got goodness knows how many because I went crazy with sowing them, thinking none would germinate. But that means we have a great supply for our poultry throughout the cold season when there is little grass for them to munch in their run.
When the plants started flowering and going to seed, I thought that meant that they were over. Instead, they made more leaves and have kept on going this year.
We have been harvesting the seeds and using it as a replacement for mustard seeds (Mustard) in curries and other dishes as it from the same family, Brassica.
They are winter cold hardy, pulling through the frosts without any protection.
They might be exhausted this season, or they might survive for another harvest. Anyway, they are a good investment.
If you are a little unsure about the cabbage/kale taste, of it just boiled, then try adding it shredded to stews, curries stir-fries: Garden Stir-Fry – the way to use up unwanted veg
