It should be on this evening's BBC coverage of the show, when they 'take a fresh look at house plants'.
A very nice section in tonight's Gardeners' World on Streptocarpus. Monty pots up the Streptocarpus 'Crystal Ice' he got from us last year, and the programme goes to South Africa to learn about Streptocarpus species' natural habitat. Scroll 3.50 into the programme.
Monty looks at his Crystal Ice cuttings on BBC Gardeners' World last night. Fast forward to 22 minutes in on iPlayer.
