This is growing on the bank (Vole County), most probably another garden escapee. The dryer habitat of the bank down to the watermeadow and the gaps left after the removal of at least eight pampas grasses has resulted in a number of different saplings, as well as wildflowers, ferns and grasses, growing up as nature has taken over the space.
We have a mature Himalayan honeysuckle in the top garden and have been mistakenly calling it the Shrimp tree because of its maroon shrimp-shaped blooms from June to September, which turn into deep purple berries in the autumn. Other names for this shrub are Flowering Nutmeg and Pheasant Berry – I wonder if this is for the gamey smell of the berries when squashed – and the Shrimp Plant is actually a houseplant. This shrub has green leaves delicately shaded with wine red and gold. It is said to be vigorously-growing and could reach 2.5m.
