Our Window on Westonbirt volunteers have explored the arboretum this week to let you know what's looking its best. Keep an eye out for the following seasonal highlights - they're not to be missed! You can also use our Arboretum Explorer to discover more tree locations around the arboretum.
Harlequin glorybower
Noticeable this week are the distinctive fruits of the Harlequin glorybower (Clerodendron trichotomum). Native to Japan and China, each crimson-maroon calyx bears a bright turquoise blue berry which eventually turns black when ripe. Look out for this tree at the top of Morley Ride.
Euonymus oxyphyllus
The Spindles look good at the moment. On Pool Avenue look for a cluster of spindle trees (Euonymus oxyphyllus) showing off their bead-like red capsules on long stalks revealing the scarlet-coated seeds within. Native to Japan and Korea.


Blue hawthorn
One of the most striking hawthorns is the Blue hawthorn (Crataegus schraderiana) situated near the dew pond off Main Drive. The tree is covered in masses of deep purple red fruits. Native to Greece.
