Petunias are versatile bedding plants which add colour to the spring and summer garden
 |
Petunias are incredibly popular annual bedding plants, and this is no surprise if you consider their enduring charm and versatility. In temperate and sub-tropical climates they can be planted year-round, but show at their best in the cooler months. In areas with colder winters, they work glorious magic throughout the spring and summer.
Extensive hybridisation has resulted in an astonishing range of growth habits, sizes, petal shapes and colours. The plants may be compact or trailing, and whilst the standard varieties grow to 30cm tall, the dwarf hybrids reach only half that height. Petunias flower in every shade of red, pink, purple, mauve, blue, white and yellow. The blooms may be single or double, ruffled, frilled or fringed, mottled, striped and veined.
Prepare your beds in advance, loosening the earth thoroughly to ensure good drainage. Petunias need generous watering, but won’t thrive in muddy, water-logged soil. To encourage growth, add lots of mature compost, and a gentle sprinkling of phosphate-rich fertiliser. They love warm, sunny positions, so are ideal in multi-layered flower-beds, and as colourful companions to pansy and alyssum in herbaceous borders, or sprawling rockeries.
Petunias add vibrant appeal to patio pots and hanging baskets, and make splendid bordering plants for walkways. Petunias harmonise charmingly with summer bulbs, and provide excellent contrast against the green foliage of shrubs and perennials.
