Clematis: Clematis 'Henryi'

description for "Clematis: Clematis 'Henryi'"

'Henryi' clematis bears very large flowers that sometimes reach 8 inches in diameter. The anthers are brown and show up nicely against the white background. There are eight sepals, and they overlap. This variety is well over 100 years old and still considered superb. 'Henryi' is a member of Groups 2a and 2b (Groups B1 and B2) clematis – prune only after flowering, to shape, or to remove dead wood. The Group 2 clematis flowers on wood produced the previous season AND on the current year’s growth. However, the Group 2 differs from Group 1 in that they flower both in the spring and then again either intermittently through the summer (Group 2b) or in the fall (Group 2a). To encourage additional blooms, Group 2 clematis should be deadheaded after the initial spring bloom. Provide full sun to part shade and consistent moisture. – edited by dtd pbcouchman
