<p>Winter hardy, Allegro is a compact, uniform, multiflora type producing a mass of bright blooms both with and without faces. The flowering ability makes it a first class choice for colour in autumn, spring and early summer, in beds, borders and containers. Height 6-8in (15-20cm). Major advances have resulted in the 'S1' or 'Synthetic hybrid', virtually an F1 but at a competitive price.</p><p>The term synthetic hybrid is used for seed produced by crossing 4-5 highly selected parent lines using controlled pollination under ideal conditions.</p>
