I'm a real fan of GIANT PLANTS, and this is
one of them! It's the so-called tree Dahlia, Dahlia imperialis. If grown outdoors, it needs to be treated just the same as ordinary Dahlias, the tubers
being lifted and stored in a cold dry frost-free place for the winter, and started off again in spring. The huge stems on a mature plant can be two or more
inches wide, and can soar up to 15 feet high. Mine is only a baby really, although it's already about nine feet high and still growing. I doubt it will
flower though, as our growing season outdoors in the UK is not really long enough. It needs to be grown in heat in a very high greenhouse or conservatory to
give of its best in terms of stems, flowers and foliage. Still - I can't resist this one!
