'Sweetunia Hot Rod Red' petunia will add a racy red to any sunny garden. Less than a foot tall, this variety can spread to 18 inches, so is an excellent choice for borders, mass plantings, container planters, and hanging baskets. Petunias love the sun, and will thrive as long as they receive regular watering and fertilizing. A light shearing in late summer will tidy up straggly ends and encourage another round of blooms before the nights get too cold.
