Friday 1 or Saturday 2 April
Visit the RHS Horticultural Halls for a great opportunity to buy spring-flowering plants from the UK's top nurserymen.
As well as the Spring Plant Extravaganza, you can enjoy a spectacular array of exotic orchids and buy some collectible new species at the London Orchid Show.
There will also be a full programme of talks and an indoor office space designed by three RHS Young Designer of the Year finalists.
- For a full list of talks, and to book tickets for the two days, which run from 10am-5pm, as well as a preview evening the night before from 6pm-9pm, see www.rhs.org.uk.
