Overview
Rich buttercream-colored, 2-3," fully double flowers.

When planted at the same time, Arenas start to bloom approximately two weeks after Mariachis. Group 3, for late spring, summer, and fall harvest. Lisianthus is also known as prairie gentian, Texas bluebell, and showy prairie gentian. Pelleted seeds.
