Petunia is one of India's most popular winter-season bedding annuals, prized for its non-stop trumpet-shaped blooms in shades of purple, pink, red, white and bicolours. Compact, mounding or trailing in habit, it flowers profusely from November through March in the plains, brightening pots, window boxes, hanging baskets and borders. Easy to grow from seed or seedlings, it rewards full sun and regular feeding with sheets of colour. Grandiflora, multiflora and cascading types suit different uses. A cool-season favourite, petunia is the go-to choice for instant balcony and garden colour across most of India.
