The 'Bloomtastic' series of calibrachoas produce vigorous, heat-tolerant plants and large (for calibrachoas) blooms, making them a perfect choice for summer hanging baskets and container planters. 'Bloomtastic Yellow' is a shining example of the vibrant colors in this series. No need to deadhead spent blooms, but calibrachoas will look their best with regular watering and fertilizer throughout the growing season.
