If you're looking for inspiration, colour, or just a lovely day out, there are plenty of flower shows and other horticultural events to mark on your calendar this year.

Here's a look at some of the best and brightest gardening shows and festivals on the line-up for 2020...

Daffodil delights

To mark the 250th anniversary of the birth of William Wordsworth, four main RHS gardens, Wisley, Rosemoor, Harlow Carr and Hyde Hall, have planted enough bulbs to make each spring garden a sight to behold.

Meanwhile, in Buckinghamshire, Cliveden is staging its daffodil spectacular The Gilded Gardens (Feb 29-May 1) for the second year.

Inspired by the 24-carat gilded golden gates on the Sounding chamber and the hundreds of thousands of daffodils across the estate, you'll be able to see narcissi springing up throughout March and April and rolling displays of rarer, pot-grown varieties will be on show in the Ferneries.

Irish blooms

If you're in Dublin, don't miss Bloom (May 28-June 1), a show spanning 70 acres of Phoenix Park, with show gardens and other attractions based on other successful shows such as Chelsea and Hampton Court.

Launched in 2007 by Bord Bia (the Irish Food Board), Bloom has numerous highly creative gardens and plant displays which are used to inspire and excite the public about gardening and garden design.

The show gardens, created by some of Ireland's top garden designers, are the heart and soul of the five-day festival which not only focuses on flowers but also on the best food Ireland has to offer. For details visit bloominthepark.com.

Scottish celebration

This year, the Royal Botanic Garden Edinburgh is celebrating its 350th birthday with a year of community celebrations. Don't miss the exhibition Think Plastic (Jan 31-Apr 26), which brings together local artists and scientists to explore the possibilities of transferring sustainable, recyclable and environmentally-responsible plastics from the laboratory into craft and arts productions.

Garden party and giant veg

The Malvern Shows (Spring Festival, May 7-10; Autumn Show, Sep 26-27) in Worcester should be on every gardener's calendar. The RHS Malvern Spring Festival celebrates its 35th anniversary this year with a new feature, Music At Malvern, with two spectacular evenings of performances featuring the 54-piece English Symphony Orchestra led by Lesley Garrett, performing a special VE Day commemorative concert on May 8.

The following night, Radio 2's Jo Whiley will be hosting the Gardeners' Party as she plays music throughout the decades, chosen by the show's special guests. This will be along with the show's stellar lineup of experts, including Alan Titchmarsh, Carol Klein, Joe Swift, Jonathan Moseley and the new show ambassador, Chris Beardshaw.

In the autumn show, grow-your-own fans shouldn't miss the ever-popular popular CANNA UK National Giant Vegetables Championship, top quality plant specialists in the Floral Marquee and a throwback to Forties and Fifties Britain in the Vintage Village. For details visit rhs.org.uk.

TV expert advice

BBC Gardeners' World Live at Birmingham's NEC (Jun 18-21) may be a more commercial show than some of its rivals, but it packs a punch with its top-notch TV gardening experts, including Monty Don and Alan Titchmarsh, who'll be offering advice in the GW Live theatre during the show.

Visitors can admire a range of innovative show gardens and bag a bargain from the many plants and accessories outlets.
