ColorRush Blue - Petunia

ColorRush Blue is a vigorous, spreading petunia with blue flowers. Ball FloraPlant lists this selection for full sun and recommends it for larger containers, hanging baskets, and landscape plantings; its page gives a mature height of 10–12 inches and spread of 24–36 inches. [Ball FloraPlant ColorRush Blue](https://www.ballfloraplant.com/Products/Details/?phid=048807608000616). ## Growing Conditions Plant petunias in full sun and well-drained soil that remains evenly moist. Petunia cultivars differ in size and flower form, so leave space for the spreading growth habit. [UF/IFAS petunia guide](https://gardeningsolutions.ifas.ufl.edu/plants/ornamentals/petunias/). ## Maintenance Water deeply rather than with frequent light sprinkles; UF/IFAS suggests 1 to 2 inches every 7 to 10 days after establishment in Florida, adjusted for local weather and soil. Fertilize monthly with a balanced fertilizer. Pinch growing tips to encourage branching. Avoid wetting flowers and foliage while watering, particularly in rainy, humid weather.
