Climbing Snapdragon, Chickabiddy, and Creeping Gloxina: Cultivation & Garden Use

Asarina is a half hardy perennial, however it is normally treated as an half hardy annual by gardeners in cooler climates.

Most of the members of Asarina have been recently reclassified. However as gardeners used both the new and old names, the information in this page holds true for the species described.

How to Grow Asarina

When planting Asarina outdoors it is best to sow the seeds on the surface from late in the winter until the early spring.

If preparing Asarina for later transplanting as seedlings, it is best to sow the seeds indoors in peat pots three to four months before they are due to be transplanted outdoors in the early spring when the temperature will not drop below 5 degrees Celsius (41F).

Seedlings should be planted at a spacing of 30 cm into a sunny area of the garden; ideally with fertile soil, that is moist but well drained, and with a pH of 6 to 7.

Caring for Asarina

Asarina is fairly easy to look after; as they are climbing plants they should have a trellis support to grow upon.

Asarina should be well watered and fed on occasion. If you require more plants then cuttings can be taken during the summer.

Specific growing information for Asarina plant species

Asarina (Lophospermum) erubescens (Creeping Gloxina; Mexican Twist)

As a tender perennial this species is usually grown as an annual in gardens. Asarina erubescens are climbers that range in height from as little as six feet (1.8 m) to as much as 16 feet (5 m).

They make very interesting plants to grow either on a trellis or hanging from a basket in an area of the garden that has full sunlight.

Seeds can be planted outside in mid winter, or you may prefer to start them off indoors, in which case start off in early winter; about 12 weeks in advance of transplanting outside in early spring.

It is best to sow the seeds in peat pots so as to cause little disturbance when transplanting.

Plants should flower from early summer through to mid autumn and the colour of the bloom is down to the variety that you sell; often with pink trumpet sweet pea like flowers, though petals may also be lavender or white.

In the USA plants are able to grow in zones 5 through 11, and grows natively in Hawaii and Porto Rico.

Once growing it is pretty easy to care for Creeping Gloxina; water plants regularly but not excessively, if you require more plants then either propagate by taking softwood cuttings, or collect seed pods once they have dried.

Asarina procumbens (Chickabiddy; Creeping Snapdragon)

These perennials are usually treated as annuals by gardeners, though they have been known to be fairly frost tolerant. Asarina procumbens carry pale yellow scented flowers that are able to bloom from spring through Autumn. Although the plant is generally low growing (1 foot; 30 cm) it is able to creep over fairly large distances.

Plants perform best in full sunlight, but are able to grow fairly well in partially shaded conditions. Ideally soil should be sandy and well drained. It makes an ideal plant for rock gardens, hanging baskets, or for trailing over a wall. Asarina scandens is also known as Chickabiddy.

Native to Mexico and the southwestern United States, these perennial climbers are loved for their showy, snapdragon-like flowers, which appear in a variety of colors from spring to fall.

Asarina plants thrive in full sun to partial shade and require well-drained soil. These climbers are excellent for hanging baskets, containers, or trellises.

Regular watering and feeding are required for these plants to thrive, and they should be protected from strong winds.
