Gardeners' Notes:

Positive DesignerDonna On Mar 31, 2014, DesignerDonna from Norwood, MA (Zone 6a) wrote:

Show 'n Tell, classified a laciniated dahlia in the U.S. (fimbriated in Europe), is a late bloomer here in zone 6a. If we have a long growing season, it will bloom nicely, but not prolifically.

If you can wait for a bloom and it is grown properly, the flower is simply gorgeous.

Just spectacular A size A flower - 8-10" even smaller blooms are smashing. - a massive grower even with the stems over 1 inch in diameter it needs to be staked. It blooms at 7 feet tall in zone 9 in mid-July through September (although it is supposed to be only 5 feet tall). I don't disbud mine because I'm not looking for size with this one. Treat with fungicide toward the end of the summer because it becomes prone to mildew in late August. Leaves are huge. Put one of these in a vase and they last at least a week. You can pick them fairly closed and still have them open indoors. Everyone will be bowled over.
