Our gardens are full of them at this time of year, but the Tulip actually originates in Central Asia. These species Tulips are varied in height, colour, foliage and the ease with which we can grow them at home and so this week on Talking Dirty, Cambridge University Botanic Garden - who hold the National Collection of Species Tulips - are along to share some of their favourites and recommendations for which to grow, and how. Plus stories of their latest adventures in Kyrgyzstan where they've been finding and protecting new varieties.

So join Alan Gray, Thordis and Simon Wallis and Kathryn Bray of the Botanics for a tantalising tour of their collection!
