Asarina wislizeni 'Red Dragon' is a beautiful variety with deep purple-red flowers that turn magenta-pink. Its flowers are reminiscent of snapdragons. They appear along the stems from summer until the first frost. They will even bloom into winter if protected from frost. It is a perennial plant with a tuberous root, but not very hardy. It is often grown as an annual or in pots to protect it from cold in a conservatory or unheated greenhouse. Climbing or trailing, this asarina is wonderful in hanging baskets, containers, or for adorning a small structure. It likes warmth and will thrive in moist but well-drained soil, in any exposure.
Asarina wislizeni 'Red Dragon' is a hybrid horticultural selection. One of its ancestors, Epixiphium wislizeni or Maurandya wislizeni, is a creeping botanical species with sandy soil origins in the desert areas of the southwestern United States (Texas, Arizona) and northern Mexico. There have been recent changes in the classification of asarinas: among them, asarina, maurandya, lophospermum, and epixiphium are distinguished. All these plants, once classified in the Scrophulariaceae family, have been moved to the Plantaginaceae family. Asarina wislizeni 'Red Dragon' is a plant with a tuberous, pivot-like root and voluble, climbing, or trailing stems. Its above-ground growth persists in frost-free winters, but its root can withstand a few degrees of frost in dry soil (-5°C (23°F) at its lowest point). In this case, the aerial growth is destroyed, but the plant produces numerous stems from its root in spring.
The 'Red Dragon' asarina grows rapidly, with stems that can reach 1.2m (4ft) in a season, or a little more in open ground. The flexible stems crawl on the ground or cling to their support using leaf petioles transformed into tendrils. They are adorned with pale-green to bluish-green heart-shaped leaves with toothed edges. Flowering begins in July and continues until the first frost. If the plant is stored frost-free, it can continue to bloom in winter. The tubular flowers appear in the axils of the leaves, along the stems. They are elongated trumpet-shaped flowers composed of a tube that slightly widens into 5 lobes. Each flower can measure up to 7cm (3in) long. The inside of the corolla is illuminated with a speckled cream throat. The flowers give way to the formation of capsules containing multiple seeds.
Asarinas are ideal plants for unheated conservatories. Outdoors, their rapid growth allows them to climb in one season on bushes or small trees, as well as on wire fences and trellises. Like ipomoeas or sweet peas, they can be hung in baskets or allowed to run in rockeries above walls. The key is to provide them with warmth, non-scorching sun, and soil that doesn't dry out too much. It is also possible to dig up the tubers before frost and overwinter them frost-free with very little watering.
Attention! These seeds are reserved for highly experienced gardeners who are accustomed to sowing very fine seeds. These seeds are as fine as dust, barely visible to the naked eye.

Botanical data
Sow from early February to mid-April in good potting soil, barely covering the seeds with a very thin layer of compost or vermiculite. Germination takes 14 to 21 days at 18-20°C (64.4 to 68°F). Light promotes germination and heat is essential. It can be useful to enclose the sowing in a polyethylene bag.
Once they are sufficiently developed to be handled, transplant the seedlings into 7.5cm (3in) pots and grow them in a cooler environment, repotting if necessary. For outdoor planting, gradually acclimatise the young plants to outdoor conditions and transplant them at the end of spring, after the last frost. Space them 30cm (12in) apart. Choose a sunny, but not scorching, sheltered location and plant in moist, well-drained soil. In very acidic soil, a pinch of lime is useful before planting to alkalise the substrate. To help the plant to climb, provide a support for it to attach to: a trellis, wire, etc. When suspended, the stems will gracefully droop.
Asarinas grow well in a greenhouse or conservatory, in pots with a diameter of 18 to 20cm (7 to 8in). The temperature should not drop below 5 to 7°C (41 to 44.6°F) in winter.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

It will vary according to where you live:
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
