About Petunia
Petunia hybrida is a fast-growing annual in the Solanaceae family. It reaches around 30 cm tall and 40 cm wide at maturity, with evergreen foliage. Purple, pink, red, white and blue flowers appear for much of the year.
Where to grow Petunia
Petunia suits warm-temperate, subtropical and Mediterranean climates and grows best in full sun. It is frost tender, so protect it from hard frosts or grow it in a sheltered spot or pot.
Soil & planting
Most soils suit Petunia provided drainage is reasonable. Plant into well-prepared ground, firm the soil around the roots and water deeply to settle it in.
Watering & feeding
Petunia does best with regular, moderate watering. Apply a balanced fertiliser in spring to support healthy growth. Keep a newly planted specimen evenly watered through its first season; established plants can then follow the water needs above.
Pruning & care
Prune Petunia after flowering to keep it compact and encourage the next flush of blooms. Its ongoing care level is moderate maintenance.
Using Petunia in the garden
Petunia earns its place for pots and courtyard containers, hanging baskets, a feature or specimen planting and feeding bees and pollinators. It is equally at home in the ground or a large pot on a balcony or courtyard.
Companion planting & design
Build the planting around neighbours suited to the same regular, moderate watering and warm-temperate climate as Petunia. Repeating the foliage or flower colour nearby will make the composition feel deliberate.
