Euonymus fortunei 'Kewensis' (Kewensis Winter Creeper, Kew Euonymus)


Michael's Opinion

An excellent plant but must be planted where it can be seen. It is slow growing and patience is required until it forms a good patch. Partial shade and a little moisture during the summer will encourage good growth.
