You get more for your money with this new 120cm-tall Thompson & Morgan Digitalis, as unlike traditional foxgloves, each plant throws up multiple stems. It's not for the fainthearted, but the white bells speckled with claret certainly look dramatic. The 'split' part of the name comes from the divided lower lip of each flower.

Gardeners can't get enough of Heucheras right now, and this is another to add to your wish list. A new introduction from Hillier Garden Centres, it's a welcome addition to their Sweet Delights range, and does well in containers. The foliage changes from season to season, from chartreuse to red and back again. Photograph: Hillier
This new flower from the French Cayeux nursery is one of three being launched at Chelsea this year. Coeur D'Or has an orange blossom fragrance and is 'healthy and robust', according to the breeders. Photograph: Cayeux

This new introduction from Hardy's Cottage Garden Plants looks great in the border and also makes a great cut flower, according to perennials expert Graham Rice Photograph: Hardy's plants
Robert Myers uses this plant in his show garden for Cancer Research this year. This tree's been a bit of a pariah, partly for its suckering habit, and partly because it's often seen in out-of-favour 'bungalow gardens'. But there's a lot to like: tactile furry stems, autumn colour and an architectural shape. Photograph: Matthew Ward/Getty Images/Dorling Kindersley
A Chelsea show garden without a few astrantias, commonly known as masterwort, is a rare thing indeed. This brilliant perennial is an old cottage garden plant that's come back into favour, as it provides excellent ground cover and is a good foil to other more dramatic blooms. Watch out for the deep red Astrantia ‘Hadspen Blood’ in the Laurent-Perrier garden, the greenish-white Astrantia major in the Marshalls garden and 'Sheila's Red' in the QVC garden.

Hang on a minute, busy lizzies at the Chelsea Flower Show? Yes, this tragically uncool plant is making a comeback via the Quilted Velvet show garden. I am not sure what the judges will make of the bed of lavender busy lizzies (perhaps it's meant to make you think of quilted toilet roll?), but this could be a new start for the flower beloved of gaudy pub hanging basket displays.
