Petunia, native to South America. The common garden petunia is an ornamental plant whose showy trumpet-shaped flowers make it popular for summer flower pot stand and window hanging basket.
Its flowers bloom profusely from early summer until frost. The plant grows well in temperate climates and does not tolerate shade.
The innumerable horticultural varieties fall into two general types: the compact erect type, reaching 15–25 cm (6–10 inches) and adapted for summer garden flower pot, and the sprawling long-stemmed balcony petunia, which grows to about 46 cm (18 inches) and is often potted in hanging baskets. The flowers range from pure white to deep crimson or purple and are often speckled or veined in contrasting colors. There are single- and double-bloom varieties.
