Taxonomy of Winter Jasmine Plants:
Plant taxonomy classifies winter jasmine plants as
Jasminum nudiflorum. For research purposes, note that
Jasminum polyanthum also sometimes bears the common name, "winter jasmine" -- just another example of why we use
scientific plant names to avoid confusion.
Botany of Winter Jasmine Plants:
Botanically-speaking, winter jasmine plants are classified as
deciduous perennials. They are considered
vines or viny shrubs.
USDA Plant Hardiness Zones for Winter Jasmine Plants:
Winter jasmine plants can be grown in
planting zones 6-10.
Characteristics of Winter Jasmine Plants:
Winter jasmine plants reach 4' in height with a width of 7' when unsupported. Supported, they can reach 15' in height. The 1"-wide yellow blooms appear in late winter/early spring prior to the leaves but, unlike most jasmines, are not fragrant. Stems stay green in winter.
Sun and Soil Requirements for Winter Jasmine Plants:
Grow winter jasmine plants in full sun to partial sun, in well-drained soils.
Uses for Winter Jasmine Plants in Landscape Design:
Winter jasmine plants are
creeping vines. If you do not want to take the time to
build a wooden arbor or use a similar structure on which to train the vines, winter jasmine plants can still be useful as
ground covers. In the latter role, use them for
landscaping on slopes, for instance.
Plant Care for Winter Jasmine Plants:
Prune winter jasmine plants in spring, after they have bloomed.
Caveat in Growing Winter Jasmine Plants:
Unsupported winter jasmine plants grow as viny shrubs and can be somewhat
invasive, since the stems put out roots wherever they touch the soil. Conscientious pruning is required to keep such winter jasmine plants from spreading where they are not welcome. This requirement is less pertinent to winter jasmine plants trained as vines. By tying their stems to arbors or trellises, you minimize ground-contact and, consequently, opportunities for rooting.
