Perennial & Biennial Seeds


Biennials live for 2 years, whereas perennials live for longer. As a general rule, biennial and perennial seeds should be sown in spring, but some can be sown in autumn as well. Many varieties will self-seed after flowering, giving you even more plants!

Lupin 'Tutti Frutti'™

Lupinus

The highest quality Lupin ever grown from seed! T&M flower breeders have done it again! Many years of breeding and selection have now given us this stunning new Lupin Tutti Frutti™. Never before has there been a Lupin with as high a quality flower spike from seed. Normally, to get this quality, you would have to buy expensive cutting raised plants. Not only has Tutti Frutti™ been bred for its many large, top quality flower spikes on each plant, but it is also first year flowering from seed. Tutti Frutti™ has also been specially selected for its mouthwatering range of attractive bicoloured flowers, in many different colour tones, many never seen before. This spectacular mixture is sure to add height, character and interest to the borders in your garden. T&M is offering a unique opportunity to grow this high quality Lupin selection at a fraction of the cost of cutting raised plants.

Commelina dianthifolia

Bird-bill Day Flower, Widow's Tears

 Customer Rating

A very rare plant indeed. This is one of the few plants with such intense blue flowers and that will also perform well in the garden. Flowering in its first year with 2.5cm (1in) gentian blue flowers, it then produces tubers and springs back to life the following year with an unceasing display of blooms. Wonderful in containers, rock gardens and the border (regardless of soil conditions). Hardy down to -8/-10C. Flowers summer. Height 15-30cm (6-12in.)

Poppy 'Coral Reef'

Papaver orientale, Oriental Poppy

 Customer Rating

A chance discovery on T&M research grounds has led to the introduction of this spectacular NEW true orientale poppy. Large vibrant flowers, often 5in. across of an intense and vivid coral pink never seen before in true orientale poppies from seed and rarely matched in the entire flower kingdom. Unlike many orientale poppies available, because it has been bred from seed it has consistent vigour, with many flowers over a long flowering period. Also it is not prone to 'flopping over' a fault with many varieties of this type of poppy. It is a long lived perennial making large plants within 3 years. From a late Autumn sowing it will flower in its first summer, coming true from seed. In a mixed orientale poppy trial the bees had apparently been very active as a red flowered hybrid produced several plants of this vivid pink. T&M's breeders got busy and... Coral Reef was born!
