We're intending to significantly increase the quantity and variety of the edible perennials in the garden, mainly in the form of additional fruit bushes and trees, but all the new plants we've bought recently will be described in Part 2.
In this Part 1, we're summarising the edible perennials we already have growing in the garden.
Growing in the ground
Rhubarb (unknown variety) - we've three crowns planted next to the raised bed area, and these produce a lot of stems throughout the year. Very undemanding to grow, it needs next to no attention at all.
Chives - not a fruit of course, but then strictly speaking neither is rhubarb ... There's a patch of chives in the raised bed area. Being an allium, it's evergreen, can look a little straggly in winter, but it comes back strongly again every spring. If left to flower it becomes a magnet for the bees. With nothing to do except harvest the leaves as required, it's the very easiest edible perennial you can grow.
