Tradescantia Information Plus 19 Fine Varieties



Tradescantia Plant

Tradescantias are unfussy plants that grow almost anywhere and provide vibrant color in summer.

Tradescantia is often a welcome invader to garden borders where it readily self-seeds and can become a permanent fixture.

Known as spiderwort, perhaps because of its narrow, strap-like leaves, the genus consists of 71 species of perennial plants in the monocot family Commelinaceae. It can be found growing wild in the UK, in clumps, or individually in wooded areas.

Tradescantia species are weakly upright, scrambling plants that can reach 75cm in height. Some varieties are more compact, however, and reach heights of just 30cm.

Their most recognizable characteristic is their three petalled flowers, often lavender-blue, with six yellow anthers in the middle.

Tradescantias was introduced to Europe in 1629 with the now naturally occurring T. virginiana. The genus takes its name from the 17th-century plant hunter John Tradescant, the Elder.

While the plants tend to have a trailing habit – great for hanging baskets or summer window boxes – they have been extensively propagated since their first arrival for borders and containers. The most commonly available variety is T (Andersoniana Group), also known as T. x andersoniana.

All the cultivars included in this group were cultivated by cross-pollinating T. virginiana, T. ohiensis, and T. subaspera.

Three other species, known collectively as wandering Jew, are not fully hardy in the UK. The shade-tolerant T. fluminensis has small, green leaves and white flowers and has been known to overwinter in southern England.

Others, sold as houseplants for their foliage interest, include T. pallida, which has variegated leaves of green and purple or red, and T zebrina, which has stripy leaves of white and green.

All hardy tradescantias grow in various soil conditions as long as they are not in the shade for the entire day. In addition to blue, flower colors in modern hybrids can be found in various hues, including purple and pink.

The plants do not require much care. Once a plant has finished flowering in mid-summer, it should be cut back to encourage a second bloom in the autumn and prevent seeding, if unwanted. Cuttings can be taken in the spring.

Tradescantia is not particularly susceptible to pests and diseases, although the fleshy leaves may be tempting to some garden pests such as slugs.


Carol Carthy, proprietor, Nillrace Nursery, Leeds, Yorkshire “The Tradescantia (Andersoniana Group) border type needs sunny, well-drained conditions. It will cope with a tiny bit of shade but needs the best part of the day in full sun.

It doesn’t like to be waterlogged but is easy to grow and take care of. It bulks up and clumps up double every year.

” Tradescantia is one of the easiest border plants to grow. I sell quite a lot. Many people don’t know what it is, but once they do, they are quite tempted to buy. The only problem is that once it’s finished flowering, it looks awful.

“My bestsellers are T (Andersoniana Group) ‘Concord Grape,’ which is a nice deep purple; little Doll,’ a very pale blue plant; and ‘JC Weguelin’ Award of Garden Merit (AGM) – a taller, pale-blue variety. Then there’s ‘Bilberry Ice,’ a nice little one that’s only been around a few years.

“We propagate on site. The plants can get a bit nibbled by slugs and snails in the nursery, but in the garden alongside the nursery, which we open for charity, it’s not a problem. The only problem is when they have finished flowering – it is then a case of deadheading and tidying up.”

Kevin Marsh, grower, Beeches Nursery, near Saffron Waiden, Essex “Are really easy to grow, but some people don’t want them. I don’t think they’ve ever been particularly in fashion. The problem is that they hold their old flowers when they fade, so they look like a mess after flowering.

“Most people associate them with granny’s garden. There are nice colors, though. T (Andersoniana Group) ‘Osprey’ AGM is a bestseller with white and blue flowers, and ‘Perrine’s Pink’ is a dusky pink with a greyish leaf.

“They split easily and are no trouble to grow in any soil. It’s just that they look like a mess in the hedge, and the public doesn’t like that. The plants like sun and part shade – as long as they’re not too dry, they are not fussy.”


Alastair Olcer, plant adviser, Whitehall Garden Centre, Lacock, Wiltshire “Tradescantias don’t need much care at all, just tidying up after flowering. They’re pretty easy, really. We display them as an A-Z line because we don’t sell vast quantities.

“The only recent promotion we have done is for Hillier’s T. (Andersoniana Group) ‘Sweet Kate’ four years ago when we did a big push because it was new. It’s now our bestseller because it has yellow leaves and blue flowers, so it stands out.

“Other Tradescantia varieties we stock are T. (Andersoniana Group) ‘Bilberry Ice,’ ‘Osprey’ AGM and ‘Blue Stone.'”
