Andrew Duff, director, Inchbald School of Garden Design "Everyone was expecting a disaster last year but it was brilliant and I think this year will be just as good, if not better.
"The overall feeling will be longevity and people will be thinking about what they are planting. Things have been quite experimental, but we'll see more realism generally, and that will come through at Chelsea.
"We'll see more architectural plants coming back. We are over the purples and plums and I think we'll see much brighter colours with dark, moody backdrops."
Joanna Archer, garden designer "2010 is the UN year of biodiversity so I think that Chelsea will reflect that.
"It may be through planting that encourages more wildlife into the garden, more tree planting or plants that shed seeds for birds to eat.
"We will see more naturalistic planting, such as meadow-style planting. Designers will be exploring how that can be taken into a residential garden, where there isn't much spare land."
Alex Baulkwill, show manager, RHS Chelsea Flower Show "Biodiversity will be big this year and a lot of people will be tying in with that, including the RHS, which will have its own stand dedicated to it.
"Community gardening will be another trend and the Eden Project is taking up the whole of the triangle with its exhibit.
"There will be a broad range of design styles, from the very traditional to the realistic, but with a fun edge.
"Because of the time of year, you always get the purples and pinks. There will be something for everyone, from the very high end to the gardens you could take home."
Sarah Bradley, garden design student, Inchbald School of Garden Design "I think we will see designers moving more towards bright colours and making a big, bold statement with colour.
"That will reflect the general mood -— with people trying to cheer themselves up during the recession. It's very powerful.
"I also think biodiversity is something of an established trend that will continue to grow this year."
