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!"

Foxglove 'Illumination Pink'

 Customer Rating
  • Winner of Plant of the Year 2012 - RHS Chelsea Flower Show, Best new product at the Anglian Business Awards, Best new product at the Garden Retail awards
  • World Exclusive
  • T&M's own breeding
  • New in 2012

Thought to be an impossible hybridisation, this is the most spectacular foxglove you will have ever seen! Parentage from the little-known Isoplexis (Canary Island Foxglove) gives this exciting new Digitalis its fabulous tropical colouring. Being completely sterile Foxglove ‘Illumination’ won’t set seed, giving it an incredibly long flowering period. Unlike most foxgloves which are generally biennial, this hardy semi-evergreen is a true perennial so you will be able to enjoy its flowers for years to come. The exotic looking blooms are densely packed on sturdy stems, with many side branches, making a striking addition to summer borders. Height: 90cm (36"). Spread: 45cm (18").
