Culture

Grow in fertile, medium moisture, well-drained soils in full sun to part shade. Vining hybrids are best sited in locations where the flowering parts of the vine are in sun to part shade but the roots are shaded. Some light afternoon shade is usually beneficial in hot and humid summer climates such as the St. Louis area. Clematis vines need a trellis or other support on which to grow. Roots should be kept cool, shaded and uniformly moist. Root areas may be shaded with perennials, annuals or small shrubs. A thick root mulch is appreciated. Do not allow soils to dry out.

'Henryi' is pruned as Group 2. See pruning instructions below.

 

Noteworthy Characteristics

Clematis is a genus of over 250 species, most of which are woody to semi-woody deciduous vines climbing by twining leaf stalks or in some cases trailing over support, but in a few cases grow as freestanding or sprawling herbaceous perennials and small deciduous or evergreen shrubs. Most have flat, cupped or bell-shaped flowers. Some plants feature ornamental fluffy seed heads in autumn. Plants bear opposite, simple to compound leaves which are usually deciduous but sometimes evergreen. Compound leaves range from lobed to trifoliate to biternate to pinnate to bipinnate. Clematis is native to both the Northern and Southern Hemispheres including Europe, the Himalayas, China, Australasia, North America and Central America.

Plants are often divided into three groups based on pruning needs.

Group 1 – Flowers only on old wood (previous year). Prune after spring flowering.
Group 2 – Flowers on both old and new wood. Typically, little pruning should be done for woody-stemmed members of this Group. If cut to the ground or pruned in fall or spring, flowering will be reduced or delayed but not prevented.

오래된 나무와 새 나무에 꽃을 심는다. 일반적으로이 그룹의 우디 줄기 멤버에게는 가지 치기가 거의 이루어지지 않아야합니다. 땅에 자르거나 가을이나 봄에 가지 치기하면 꽃이 피거나 지연되지만 예방되지는 않습니다.번역된된 것이 더 어렵다.

 

Group 3 – Flowers only on new wood. Can be cut to the ground in fall or spring.

Genus name comes from the Greek word klematis which is an old name applied to climbing plants.
'Henryi' features profuse, showy, eight-sepaled, 6-8" in diameter, white flowers with purplish brown anthers cover this vine in summer. Bloom on this cultivar comes primarily from the previous year's stems in early summer, but also occurs in a second flush later in the summer on the new (current year's) growth.
