Five new plants at RHS Chelsea 2019

The RHS Chelsea Plant of the Year 2019 celebrates some of the exciting and diverse new plants launched at this year’s show.

About twenty plants were shortlisted for the award and on show in the Great Pavilion at this year’s RHS Chelsea Flower Show. Richard had a sneak preview of the plants on Press Day and chose his five favourites.

Streptocarpus ‘Lemon Sorbet’

This is a fabulous new strain of this popular houseplant. It’s the strongest yellow flower yet to bred into Streptocarpus and is a stunning combination of soft lemon flowers with lavender mauve buds.

It flowers for ten months continuously, so it’s a great choice for those spots in your home that have bright, but indirect light. Bred by Lynne Dibley and on show on the Dibleys Nurseries stand in the Great Pavilion – GPF215

Rose ‘Gabriel Oak’

This is a magnificent variety, bearing large, many petalled rosette blooms. They are a striking shade of deep pink, the outer petals of each bloom paling slightly over time.

The beauty of the blooms is enhanced by a wonderful, strong fruity fragrance. A vigorous rose; it forms a very shapely, broad, rounded shrub with mulberry purple stems and dark green foliage, giving the overall impression of richness and abundance. Named after the beloved character in Thomas Hardy’s novel, Far from the Madding Crowd. Bred by David Austin, 2019 and on show on the David Austin stand in the Great Pavilion. GPF216

Agapanthus ‘FIREWORKS’

This is an evergreen perennial with large umbels of bicolour flowers displaying rich blue bases and white flaring petal tips from July to September.

This superb new variety has bigger blooms, better colour and more stems per plant than other bicolour agapanthus. Growth is strong but short and clean and plants are suited to containers or growing in garden borders. This plant came third in the competition.


Dianthus ‘Cherry Burst’

Fans of Richard Jackson’s Garden Show on QVC will recognise this little beauty as one of the plants that has been on sale recently. Richard secured some hotly sought after plug plants of this variety and has even been growing them on his patio.
