Six zingy Zinnias to grow

Zinnias are easy to grow. They are half-hardy annuals, so need to be sown in the protection of a greenhouse or a propagator on a bright house windowsill in mid to late spring. Once they’re large enough to handle, prick them out individually and grow on before transplanting outdoors when all risk of frost has passed.
Alan Gray, owner of East Ruston Old Vicarage sows zinnias every year, for the colour they bring. “They are invaluable for providing colour late in the season,” he says. “We sow seeds of zinnias anytime from the beginning of May until mid June. They dislike cold of any kind and will refuse to grow until night temperatures are around 10°C, but sown under cold glass in late spring the seeds germinate within a few days. As zinnia seeds are large, we sow two to a small pot thinning them down to a singleton when large enough to handle.”
Zinnias make brilliant cut flowers for vibrant bunches in the house. Cut the main flower stem out for an arrangement and more flowers are soon produced from side shoots further down; strip the bottom leaves off the stems before placing them in water. And they’ll flower over a long period, up until the first frost. Here’s our pick of the best cultivars.

This new cultivar from Mr Fothergill’s has large flower heads that last well, shrugging off heat and drought should we have a hot dry summer next year. Mature plants reach around 45-60cm tall and need next to no maintenance to achieve a bright, eye-catching display.
