Varieties with the largest flowers
I was looking at the van Geest web site (http://nlvangeest.nl/wp/en/grootbloemig/) and noticed that several of their varieties have flowers as large as 24 or 25 cm (Lagoon, Spartacus, Monaco, Monte Carlo). I tend to be more attracted to mini and exotic varieties, and none of mine has produced a flower larger than 20 cm. So I have decided to buy a few of the largest-flowering varieties that are currently available in the US. For many varieties it has been difficult to find information on flower dimensions, with the exception of those from van Geest and Hadeco. So I would like to ask what are some of the huge-flowering varieties that you own?
