The Petunia x Calibrachoa ‘SuperCal’ is a brilliant hybrid plant, combining the best features of both petunias and calibrachoas. It’s a real superstar for a hot Aussie summer, celebrated for its fantastic performance and a seemingly endless supply of stunning blooms. This series is known for its strong, semi-trailing habit and a huge range of vibrant flower colours, from pink and purple to red, yellow, and white. Unlike many petunias, ‘SuperCal’ is robust and weather-tolerant, and its flowers are “self-cleaning,” which means you don’t need to deadhead them to keep them looking their best.
Caring for Your ‘SuperCal’
- Growing Conditions: This plant loves a spot with plenty of sun. Full sun is best to encourage the most prolific flowering. It prefers well-draining soil and can be grown in the ground, but it really shines in a pot or hanging basket.
- Watering: Water regularly, especially in hot weather, as the soil in pots can dry out quickly. It prefers consistent moisture, but make sure the pot has good drainage to prevent root rot.
- Feeding: To keep those flowers coming, feed it regularly during the growing season with a liquid fertiliser, diluted to half-strength.
- Pruning: The “self-cleaning” nature means you don’t need to deadhead spent blooms. If your plant starts to look a bit leggy or overgrown, a light trim will encourage a new flush of growth and more flowers.
Usage in the Garden
‘SuperCal’ is an excellent plant for adding a vibrant splash of colour to any space. Its semi-trailing habit makes it a perfect choice for pots, window boxes, and hanging baskets where it can spill over the edges. It’s also a fantastic groundcover, filling in gaps in a garden bed with its colourful display. It’s a low-maintenance and high-impact plant, perfect for patios, balconies, and courtyards.
