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.)
