If looming sunflowers are not to your taste, why not consider growing the world’s tallest Dahlia this summer?
Our clever Horticulturalists have created a towering version of the popular flower that can grow up to 8ft tall or more on fertile soils and carry hundreds of flowers.
The Tree Dahlia has been bred from naturally long-stemmed varieties sold in cut flower markets. White Lightning is the second colour available, with more sure to follow over the coming years.
As simple to grow as any other Dahlia, they can even stay outside during winter provided they’re on well-drained soil with a good six-inch covering of mulch over winter. They’ll then sit dormant in the soil over winter to re-emerge with vigour and masses of flowering stems the following year.
Strong and robust, with stems as thick as bamboo, nobody had really recognised the concept of a Tree Dahlia before these super-tall natives of Mexico were developed and cultivated.
So simple to grow, we supply them in approx. 6.5 litre nursery pots ready to grow fast; they’re a bit like Jack and the Beanstalk as the growth kicks in, so all a gardener has to do is plant in a fairly sunny spot and watch as they reach for the skies before budding up and producing massive clusters of blooms in the season. 
Dramatic and impressive, they’re fun for all ages to grow. Instead of trying to grow the tallest sunflower, now the kids can try to grow the tallest tree, Dahlia!
