Nursery contributed plant descriptions

A quick growing summer annual from Central America, bearing all summer, large, luminous orange, yellow centred, daisy-like flowers with velour stems that are perfect for picking. Robust and shrubby under ideal conditions, clothed with large, softly hairy, three lobed leaves. An exceptional annual, once seen, never forgotten, unlike graceless dwarf varieties developed for regions with too short a summer. Plenty of additional water and a well drained, rich soil, is usually required for maximum magnificence. An attractive alternative, or compliment, to summer vegetables in the veggie garden. May self sow but it's best too collect some seed as insurance for the following year. Plant individually, 5mm deep, where they are to grow in spring, after any danger of frost, or start singly in pots, making sure to plant them out before they are too large, two or three pairs of true leaves is about right. Each pack contains a garden spectacle of 50+ seeds.
