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!

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!

Verbascum x hybrida 'Copper Rose' F1 Hybrid

Mullein, Celsia

The robust plants are actually incapable of setting viable seed, so we must offer seed which has been pollinated meticulously by hand between the two parent plants. As with most F1 Hybrids, special factors are tremendous vigour and a plant that just keeps on flowering, as it tries to produce seed which it cannot do. The gorgeous silky, large blooms will smother the soft, silver stems which reach up to 3ft. A great range of fashionable and delicious colours - ranging from copper to buff, apricot, old rose, tan and other lovely blends, all bursting from the contrasting silvery-grey flower spikes and buds. Sown in January/February they will easily flower during the summer of their first year, and if cut back will often re-bloom. An excellent performer. More info
