Hells Petunias are a series of petunias with brightly coloured blooms - the perfect hot colours for the heat of summer. Blanketed in blooms from spring to early autumn, Hells Petunias have a mounded trailing habit making them the perfect choice for containers and hanging baskets. Trim off flower heads after they fade and die to encourage more blooms late in the season. This is one hell of a series - a must have for New Zealand gardeners.
