Michael Perry Advice

"Our 'garden-ready' plant range is a much larger plug plant than usual and, if the weather allows, can be planted directly into their final containers and into beds and borders from the end of May. Please keep an eye on the weather forecast though, and never plant outside if a frost is forecasted. If you have planted and then news of frost comes, then make sure you cover plants with fleece or some old net curtains temporarily."

Barberton Daisy, Transvaal Daisy
 
  • NEW in 2013
  • World Exclusive
  • These hardy gerberas have much larger blooms than standard hardy gerberas.
Enjoy 3 seasons of stunning colour with this new winter hardy gerbera! These spectacular border perennials begin flowering towards the end of spring, coming into their own during the summer. You'd imagine the plants to be exhausted by then, but no! They then go on flowering into the autumn! So many flowers - you can steal a few for the table - people just won't believe you've grown them yourself. Gerbera 'Sweet Dreams is the 'crème de la crème' of gerberas; an all-new strain with stronger stems and larger flowers than most other varieties. Height: 45cm (18"). Spread: 40cm (16").

Please note, that within our 2013 spring despatch, some plants supplied may have a white centre rather than dark, however the plant will offer the flower power and garden performance.

 
  • Alan Titchmarsh tip - "Keep your gerberas flowering continuously with regular feeding. And the more flowers you cut, the more you'll get!"
