Asparagus asparagoides aka Bridal Creeper

Asparagus asparagoides is a climbing perennial in the asparagus family, Asparagaceae. Its native range runs from southern Ethiopia to southern Africa. It grows in regions with a seasonally dry tropical climate. Gardeners know it as florists' smilax, baby smilax, or wreath lily. Another name, Asparagus medeoloides, is a synonym for this species. It is not native to Britain or Ireland.

This herbaceous plant scrambles and twines as its stems grow. The RHS gives a garden height of 8–13 feet [2.5–4 metres]. Its shorter account describes stems reaching about 10 feet [3 metres]. Plants spread about 5–8 feet [1.5–2.5 metres] across. They can reach their mature size within one to two years. The glossy green leaves sometimes have a heart shape. The foliage is deciduous, so it does not stay year-round. White flowers appear in spring. The fruit is harmful if eaten, and handling can cause skin allergy.

Grow this tender perennial in soil that drains well. The RHS lists both full sun and partial shade as suitable. Choose a sheltered spot rather than an exposed site. It accepts chalk, clay, loam, and sand when drainage is good. Acid, neutral, and alkaline soils are all suitable. The supplied moisture guidance spans dry to moist conditions. Its UK hardiness rating is H3. This suits coastal districts and other relatively mild parts of Britain. The RHS places this rating between 23 and 34°F [−5 and 1°C].

A conservatory or greenhouse is a suggested setting for this climber. These uses suit its status as a tender perennial. Its twining form and glossy foliage provide its main visual features. Spring flowers add another season of interest. Cut back stems that die down once flowering has finished. Raise new plants from seed, or divide tubers during dormancy. Both seeds and tubers also help the plant spread.

That ability to spread can become a serious problem. The RHS identifies it as invasive in Australia and parts of North America. Consider that risk alongside its value as a garden climber. The RHS reports few usual pest or disease problems. This does not remove the risks from its fruit or handling. Wear gloves and other protective gear when working with it.
