Ilex crenata ‘Convexa’

convex-leaf Japanese holly

Outstanding Qualities

This form of Japanese holly, Ilex crenata 'Convexa', is fast growing and is a very good hedge either sheared or un-sheared. It is a handsome utility plant that is durable alternative to the slower growing boxwood. Sheared it is best when the ultimate desired size is 4 to 5 feet high and the same width or left to grow un-sheared 5 to 6 feet high and wide. Dark evergreen leaves that are convex easily distinguish the selection and make an elegant backdrop to the flower garden or provide strong form in architectural gardens. Ilex crenata 'Convexa' is durable, plastic and easy to manage, a real workhorse in the garden.

Culture Notes

This Japanese holly is easy to grow in full sun to dappled shade. It will grow best in well-drained soil, but will tolerate sandy sites or clay if the drainage is adequate. It is drought tolerant once established. It will respond well to pruning or shearing. Plants treated as a hedge will be denser in more sun.
