Broad dahlia-like double heads across the full colour range. The tall stems cut well and keep flowering as long as the plants are picked over.

Small, tightly formed pompon heads on a bushy plant. The most forgiving zinnia for a first-time grower and very heavy flowering.

The tallest of the garden zinnias, grown for long straight stems and heads that can reach ten centimetres across. Best given some shelter from wind.

A compact interspecific zinnia bred for disease tolerance in humid weather, where garden zinnias usually give way to mildew and leaf spot.

The double-flowered Zahara in a deep cherry rose, carrying the same humidity tolerance as the single types with a fuller head.

A spreading interspecific zinnia that covers ground quickly and sheds its spent flowers cleanly, so beds stay tidy without deadheading.
