Petunias have been among the most popular Summer flowering annuals over the past years with many new cultivars being produced rapidly. Petunia flowers are all trumpet-shaped but come in a range of different colours, shapes and sizes. They can tolerate various weather conditions, and soils and will thrive in full sun. They do not like to be over watered. Perfect for bedding plants for mass displays, borders, rockeries, window sills and hanging baskets.
