Sessile oak has similarly lobed leaves to English oak but with a more upright trunk and straighter branches, longer stalked leaves, and acorns with no stalks at all. Male flowers are green catkins and female flowers resemble red flower buds before developing into acorns. Leaves turn orange and brown to provide good colour in autumn.
Estimate full grown height: 20 - 40 metres, growing an estimated 20-30cm each year.
Value to wildlife: Sessile oaks offer a habitat for more than 280 species of insect, which provides food for birds and other predators. The bark also provides a habitat for mosses, lichens and liverworts, and the deadwood cavities for nesting birds and roosting bats. Acorns are eaten by birds and mammals including jay, badger and red squirrel.
Preferred soil type or environmental conditions: A hardy species that does well in most well-drained soils.
UK sourced and grown: Every sapling that we provide is UK sourced and grown to minimise the risk of importing and spreading tree pests and diseases. Seeds are collected and stored in the UK, and they are all coded and batched so that we can track each individual tree.
