Nursery Stock 0 views
Morphological characteristics: An evergreen woody vine with inconspicuous lenticels on the stems. The branchlets, young petioles, and leaf undersides are covered with short pubescence, while the old branches and leaves are hairless. The leaves are leathery, elliptical to ovate-elliptical or broadly obovate, 2-6cm long and 1-3cm wide. The old leaves are nearly green or pale green, the first flush of new leaves is pink, a few have 2-3 pairs of pink leaves, the second to third pairs are pure white leaves, and between the pure white leaves and the old green leaves there are several pairs of mottled variegated leaves; the whole plant has rich leaf coloration, one might say brilliantly colorful. Biological characteristics: Variegated Confederate Jasmine is a light-loving, strongly shade-tolerant

Biological characteristics: Variegated Confederate Jasmine is a light-loving, strongly shade-tolerant plant that prefers air with higher humidity and a well-drained acidic or neutral soil environment. It is robust with strong disease resistance and vigorous growth, similar to the native Confederate Jasmine of China, and at the same time it also has relatively strong tolerance to drought, short-term waterlogging, and cold. Its leaf color changes are related to light and growth conditions; vivid coloration requires good light conditions and vigorous growth conditions.

Scope of application: Variegated Confederate Jasmine can be grown outdoors south of the Yangtze River basin. For safe overwintering, appropriate protective measures can be taken, such as increasing light; from March to August, apply mainly nitrogen fertilizer to promote plant growth, and in September and early October apply an appropriate amount of phosphorus and potassium fertilizer to promote plant vigor; starting in October, pruning is prohibited, etc. If used as an indoor potted ornamental plant, it can be used in any region, and is especially suitable in regions with better light conditions.

Landscape and garden use: The ornamental value of Variegated Confederate Jasmine is embodied in three levels of leaf color, namely the color group formed by red leaves, pink leaves, pure white leaves, variegated leaves, and green leaves, which closely resembles a blooming cluster of fresh flowers, extremely gorgeous and colorful, and is especially at its best in spring, summer, and autumn. To achieve the best color effect, intensive pruning is needed in spring to promote sprouting branches and increase ornamental branches, while also forming a compact plant clump. In landscaping, it is an extremely beautiful groundcover plant material that can be planted in isolation strips beneath urban street trees; or used as slope-protection vine cover; it can also be used as a year-round "flowering" plant for various flower border arrangements; at the same time it is also an excellent potted plant material that can replace the current potted flower displays in parks and modern facilities, overcoming the shortcomings of short ornamental periods and the high cost of frequent replacement. In addition, it can also be used as an excellent ornamental plant for home potting.
