Unless Meghan Markle is about to break a royal tradition dating all the way back to 1840 - just imagine the furore - we're almost certain we know what plant the actress will have in her bridal bouquet.

A sprig of myrtle - as last seen in Kate Middleton's beautiful bouquet during her royal wedding to Prince William in 2011 - is an emblem of matrimony, and symbolises love and hope, and is often tradition for non-royal weddings too.

Queen Victoria began the royal family's tradition when she married Prince Albert over a century ago (via HELLO!), and Kate's myrtle came from Queen Victoria's own 170-year-old garden.

A spokesperson for Bridebook told Elle UK: 'We can certainly imagine Meghan incorporating Myrtle in to her bouquet, but doing so in her own unique way.

'She may choose to include the fruit prior to when it flowers - fruit and vegetables in bouquets are predicted to be a big trend for 2017.

'The immature fruits that eventually flower are beautiful in their unformed state and are either a striking blue-black or yellow-amber colour, either of which would brighten a bouquet and add a tasteful splash of colour.

'The leaves are also a beautiful glossy green, and carry a sweet, spicy, orange scent.'

It's also being speculated that Markle may also opt for Lily of the Valley, as the late Princess Diana featured in her wedding bouquet, and the bloom is said to symbolise trust, and the return of happiness.

Fans of Markle will probably already know that the actress is particularly fond of peonies, as she often posts images of the flowers with captions about how much she loves them on her Instagram page.

And they just so happen to be in season when she and Prince Harry are due to marry in May.

The Suits star previously posted: 'My weekly treat (and extra special thanks to Anna at my neighbourhood flower shop for finding peonies for me because she knows how much I love them!!!')

Markle and Harry announced their engagement last month, and confirmed that they would be marrying at St George's Chapel in Windsor on a date in May 2018.

Now all that remains is to find out who will design the bride's dress...
