(aka C. 'KLEC02070') Imagine a drought-tolerant, small-flowered, winter-hardy petunia cousin and you've got calibrachoa. When Jack Campbell told me these southern Brazil natives were winter hardy, I was skeptical, but our trials have proven him correct. Our more than 2 year old clump of Calibrachoa 'Minifamous Blue' (sorry, but KLEC02070 just doesn't cut it as a cultivar name) not only survived 7 degrees F, but has now made a clump to 6' wide. The stems are clothed in narrow green leaves, then topped, starting in early spring and continuing until fall, with dark blue-lavender flowers. Flowering slows during very hot summer spells but resumes as the weather cools. Good drainage and slightly acidic soils are best.
