The Tradescantia group isn't some kind of sketchy set of illuminati figures worthy of a Dan Brown novel, it's a group of houseplants with a plethora of different names: inch plants, spiderworts, purple heart, teddy bear vine, and more*. Find out how to look after them, which ones to choose and what to do when things go wrong, from spider mite to spindly stems.

Here's a list of the plants I dissuss in this episode:
1. Tradescantia fluminensis is probably the most popular of the group, historically: it's sometimes called the small-leaved Tradescantia. Tradescantia albiflora is another closely related species that you'll sometimes see for sale.
Variety T. 'Quicksilver' is one of my favourites, along with the dappled pink, white and green 'Maiden's Blush'. The plant at the top of the page is called 'Green Hill' and is a good one if you're not a fan of variegation - it's available from Crocus in the UK.
2. Zebrina pendula, the silvery inch plant, is more accurately known as Tradescantia zebrina. I have a suspicion its colourful, silvery looks are helping it overtake T. fluminensis in the popularity stakes.
3. The striped inch plant, Callisia elegans, looks like a Tradescantia in a pinstripe suit.
It's less common than either of the options above, but makes an attractive trailing foliage plant. You may see it sold as Setcreasea striata.
4. Tradescantia pallida 'Purpurea' aka Setcreasea purpurea aka purple heart aka purple spiderwort. Phew. Beautiful rich purple foliage if you give it enough light.
And also ...
Tradescantia spathacea aka Rhoeo discolor is another member of the clan, but has quite a different growing habit to the others already mentioned, with more of a rosette formation. Its most interesting feature is the way the flowers are cupped in little 'boats' at the base of the leaves, hence the common name moses in the cradle. Siderasis fuscata or brown spiderwort is a terrarium dweller and another Tradescantia group member, albeit one that, in my humble opinion, is too boring and fussy to be of much interest.
*Another common name is wandering Jew, but I purposely avoid this racial epithet, when there are lots of other more descriptive common names available.
