Penn's Gift is a monster, fuller than Emory Paul. Ivory Palaces is large and full. Kelvin Floodlight- a large dinnerplate. There are probably 10,000 others..

Follow the link to many gorgeous blooms from Wynne's Dahlias. They specialize in large dahlias with many original varieties. And oh so pretty I might add!

The summer of 2003 we had a Wanda's Moonlight with a bloom that measured 17" across & 14" deep! It was the first bloom & down in the plant so I couldn't get a really good picture of it but there are pictures of later blooms on the same plant in our albums at the site given in the previous answer. Sir Alfred Ramsey is another biggie but very frequently will "beard" so is not as attractive as some. We won Best AA & Biggest in show in 3 shows in 2003 with Zorros that were huge. They have a wonderful form & don't sag on you! Love those AA's that are a bouquet in themselves!

My Maki was just as big as my Emory Paul, about 15 inches.

Maki is a variegated sport of Emory Paul... this means that they share virtually the same genetics, with a slight aberration in the coloration genes. Potential size stays the same typically in sports.

If a new dahlia grower is interested in the 'giants,' check out US dahlia vendors/growers that offer AA-sized varieties. 'AA' is dahlia-nerd talk for 'giant.'

You can also search a really useful database of dahlia varieties called DahliaAddict for the large ones, of any color/form imaginable. Have fun!
