A lovely lilac purple ball bloom, lighter than Robann Royal but a good companion to it. Blooms are about 3" wide, plants are strong producers.
Grows about 5-6 feet tall in my field.

This listing is for 1 tuber, that should have visible, swollen, or slightly growing eyes. They can be planted outdoors after all risk of frost, or started indoors a few weeks before your last frost in a 6" pot, as long as you can provide supplemental light.
Where to buy Robann Regal dahlia tubers? You can buy them right here at Green Garden Mama! We typically have dahlia tubers for sale in January each year, and ship in April as long as the weather is safe for shipping.
