Crack Willow (Salix fragilis)
Small and rapid growing, Crack Willow pollards have lived as long as 1000 years across the UK. Unpollarded, they tend to split open under their own weight. Evelyn, writing in the 17th century when it was also known commonly as "sally" or "wully", thought the roots slower growing but deeper than other salix. There are an enormous number of species in the genus, of which apparently 27 are native to the UK. Crack willow is one of the biggest. Salix root easily and typically need wet conditions. They are useful hedge plants too in these conditions, where they will establish and grow on very quickly. They hybridise freely.
Value For Wildlife
They seem to be second only to the oaks in terms of dependent species, which include several small mammals. The Crack Willow is dioecious - male and female flowers appear on separate trees. Crack Willow male flowers are in the form of yellow catkins, which are an important source of early pollen and nectar for bees in the critical period of early spring, and are a food source for the caterpillars of the Comma.
Willow pollards are a defining characteristic of traditional lowland river and wetland landscapes like the Somerset Levels, and their rapid regrowth has led to biomass experimentation - we include them in our trees for wood fuel collection. Like other willows, Salix fragilis can be used for weaving.
Plants For Sale
Like all our native trees and hedging, our crab apple plants have UK provenance and origin - that's to say they're British grown using seed from trees here.
