New product development manager Michael Perry said: "Every gardener loves a fuchsia but it tends to be the same old varieties that get used again and again in the same old way - 'Lady Boothby' as a climber, 'Annabel' as a basket plant and F. magellanica as a hardy shrub.
"We're launching stunning modern fuchsias that will drive the genus forward and change the way people think about using these plants in the garden."
He added: "'Beauty Queen' is the world's largest flowering hardy variety while 'Pink Fizz' is a second-generation climber that will flower from the top of the plant right down to the base. 'Bella' is a mini-fuchsias collection.
T&M's breeding programme has created Nasturtium 'Phoenix', which has split petals and is scented. It has been made T&M flower of the year for 2015. The plant was previously sold as 'Flame Thrower' but is now available as a 25-seed packet for £2.49.
The firm is also launching several scented carnations in a Scents of Summer collection, including old favourite 'Mrs Sinkins', the double 'Cerise' and black Carnation 'Blackjack'. Raspberry Ruby Beauty is a new patio variety that is available in T&M's seed catalogue.
