One of the most floriferous Dahlia's available. The perfectly symmetrical flowers of Wizard of Oz just keep on coming, until late in autumn she is enchantingly beautiful. (Do remember to keep removing the faded old flowers!) Wizard of Oz is a sturdy plant that is also suitable to be planted in large pots and containers. When you plant a Dahlia in a pot or container, so remember that she needs a lot of water when she is in full foliage and bearing lots of flowers.
