Perennial Broccoli

Sunday’s allotment haul included the first head from one of our two perennial broccoli. I’m quietly pleased by this, as OH was becoming pessimistic about our chances of a harvest, but I haven’t admitted to him that I have some rather different doubts about them.

Those doubts are threefold:

1. How are they going to cope when we take the brassica cage off them and move it to its new location? Will they be destroyed by cabbage whites/birds?
2. How much staking are they going to need? They are already pretty tall, and can only get taller over the next two to three years, and that means quite a lot of support.
3. What do they take from the soil over their lifetime? Brassicas are hungry feeders and perennials always change the soil composition around their root system, so a perennial brassica is going to be pretty demanding of its surroundings.

The seed companies have very little information about harvesting and maintenance of the plants, which I find is an increasingly common problem with seed packets – everything is treated like an annual, even if it isn’t!

That apart, the flavour is excellent and it’s going to be interesting to get these tall plants incorporated into edible landscaping, where they can provide height and structure for a planting scheme that aims to be attractive, useful and environmentally low-impact.

Good luck with the perennial broccoli...have never heard of it before. And I'd say that when in doubt, dump plenty of well rotted manure on it ;)
