Do Dahlia's.

Revert back? I bought a very pretty one called Art Deco from trademe 2 years ago. Was such a pretty purple/blue and white. Flowered first time last spring, BUT this time in they are just a boring ole plain purply colour? Any suggestions please, many thanks.

Blame the bees.When they are busy pollinating they carry pollen from other plants which is usually from more dominant plain varieties.

If the plant is from the original tuber, the bees probably can't be blamed. From seed, perhaps - but unless the bees are into burrowing. I think there might be something else going on. Try this link - Gardenweb is a great site for answering questions -
