Bred by owner Jimmy Jones, they include some of the most scented varieties of Nemesia yet developed. They include Nemesia Maritana 'Vanilla Lady', 'Scented Lady', 'Sweet Lady', 'Raspberry Ripple' and 'Blueberry Ripple.'
All five flower in early spring to late autumn, grow to 37cm and work well in tubs, baskets or in the garden in well-drained soil.
'Vanilla Lady' has scented white flowers with a yellow eye. 'Scented Lady' is scented violet blended with white. 'Sweet Lady' has scented pink flowers blending into lemon, and 'Raspberry Ripple' and 'Blueberry Ripple' boast scented bi-colours of light violet and white.
Jones said: "They took three years of breeding and I'm planning on having them ready as perennial seed for Chelsea, though it will be very tight with the timing.
"There will be pink, blue and white collections and we hope to sell anywhere in the world through a website we are developing."
The plants are available through Channel Island Plants and agents worldwide. Major growers including Kernock Park Plants, Ball Colegrave and Delamore are already building stock.
Jones added: "We are unique because our plants are all virus-clean - they go direct from our lab in Scotland to Channel Island Plants. My plan is to start breeding a lot more colours and get everything self-bushing."
