Kitten Grayson Flowers will create a bower of trees at the show’s London Gate entrance, featuring English oak for Harry and Californian cedar for Meghan, as well as woodland flowers.
The entrance to the Great Pavilion will also be adorned with floral displays on a royal theme, courtesy of Hillier and its designer Sarah Eberle.
A Royal Celebration By Hillier will feature trees, which Hillier is best-known for, complemented by flowers with names such as Lavandula Regal Splendour (lavender) and Cotinus Royal Purple (smoke bush).
The main Hillier garden, which is in the Great Pavilion, is always a romantic affair and this year its Stihl Inspiration garden will include 8,000 trees, flowering shrubs and flowers and a walkway through the middle so the public can see it properly.
Similarly, designer Jo Thompson can always be relied upon to produce a romantic Chelsea garden and this year she was asked to create a feminine garden by her sponsor Wedgwood, the fine bone china company.
“The brief was for a feminine garden so I looked through my previous designs and they had all been a garden for a man in his 20s or for couples and had never been for a woman,” Jo admits, adding: “It doesn’t have to be pink and fluffy. I wanted the structure to be delicate and strong.”
As a result The Wedgwood Garden is like a modern-day willow-pattern tea garden with a bronze sculpted “tea pavilion” at the centre, a stream with rocks and boulders, stepping stones across a pond and Salix exigua trees (North American coyote willows) dotted throughout.
Possibly the most romantic show garden of all will be The M&G Garden by Sarah Price, who has created a romanticised Mediterranean haven.
“My ideas started two years ago when I visited the Painting The Modern Garden exhibition at the Royal Academy and I saw a huge painting by Monet,” she says.
“There were layers and layers of paint but the effect was so beautiful and the colours were so vivid, luminous and electric.
“So I went home and started doing some collages. Why not use pinks and reds and tangerines in a garden, I thought?
“Or use acid green and mix with yellow and really have fun?”
Sarah is using lime-green euphorbias, butter-yellow horned poppies and lemon-yellow mimosa offset with an earthy terracotta background to create her Mediterranean colour palette.
“The collages led to this visual of stacked reclaimed tiles dividing spaces, raised platforms of ground earth, terracotta-earth backgrounds, Mediterranean scree-like gravel paths and meadow planting with water trickles coming down walls feeding into pools,” she says.
And for a bit of home-grown romance there’s Mark Gregory’s The Welcome To Yorkshire Garden, inspired by the beauty of the Yorkshire Dales.
Featuring a stream, buttercup meadow and stone cottage there’s also an old-fashioned cottage garden – and you can’t get more romantic than that.
