Watching Beechgrove they mentioned that Mānuka was also called Leptospermum
I'd never really thought about growing Mānuka - didn't really know what it was - before but with the imminent arrival of the allotment bees and having grown some Leptospermum's before perhaps it would be fun if we could grow some?
Apparently it's Leptospermum scoparium, commonly called mānuka, manuka myrtle, New Zealand teatree, broom teatree, or just tea tree, is a species of flowering plant in the myrtle family Myrtaceae, native to New Zealand and southeast Australia.
Wikipedia says that it is typically a shrub growing to 2–5 m (7–16 ft) tall
