Nursery contributed plant descriptions

See this Dahlia in the garden photo? That is one plant of ‘Goliath’ in its very first Summer planted in Spring! I couldn’t believe how strong and huge it became. Selected from a batch of seedlings for its vigor and ever-so-sunny yellow color, it reached a super bushy 6’x6’ by August. Loaded with blooms from a young age, it’s as bloomiferous as ‘True Wild Form’. Very mildew resistant and NEEDS NO STAKING. Tons of cut flowers and bumblebees like to sleep in the flowers. Attracts butterflies. Rich composted soil and side-dress in Spring and Summer for best show.
