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.
Purchase size and growth: These trees are cell-grown saplings, ranging from approximately 15cm-60cm in height. Cell grown trees can be planted all year round in most situations as long as they are given the correct care. Please be aware that depending upon the time of year you receive your sapling (particularly early spring) it may not look very perky upon arrival, please do not worry once it has been planted it should pick up quickly.
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 and Ireland Sourced and Grown (UKISG): Every sapling that we provide is UK and Ireland sourced and grown to minimise the risk of importing and spreading tree pests and diseases. Seeds are collected and stored in the UK and Ireland, and they are all coded and batched so that we can track each individual tree.
