Barberton Daisy, Transvaal Daisy
 
  • NEW in 2013

  • 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!"

Alstroemeria ?Butterfly Hybrids?

Alstroemeria 'Butterfly Hybrids' - Part of the Alan Titchmarsh Collection

Peruvian Lily
 
  • WORLD EXCLUSIVE
An old strain of Peruvian lilies called the ‘Ligtu Hybrids’ included some great purples, but over the years these got lost. Now only the pinks and purples have been selected to create this eye-catching mix. Your plants will be smothered with butterflies from the moment the blooms open. One of the easiest cut flowers to grow and definitely one of the most impressive. Height and spread: 60cm (24”).
Alan Titchmarsh

Alan Titchmarsh says...

"You should pull the stems of Peruvian lilies rather than cutting them. It encourages flowering for up to 6 months."
