Regal pelargoniums, sometimes called regal geraniums or Martha Washington geraniums, are the showiest of the family. Their large, open flowers are often blotched, veined or feathered in a second colour, and are borne in generous clusters from late spring into summer. They are plants to grow close up, where the detail of each flower can be admired.
Some of our favourites
Where to grow them
Regals are at their best under cover: in a conservatory, a greenhouse or on a bright, cool windowsill. They can stand outside in a sheltered spot through the warmest months, but heavy rain spoils the flowers, so a porch, veranda or covered patio suits them well.
Growing regal pelargoniums
Give them plenty of light, good airflow and a free-draining compost, and water carefully, letting the surface dry between waterings. From February, feed with an organic seaweed feed or tomato feed, then switch to a high-potash feed from June to extend the flowering season. Regals prefer cooler conditions to many pelargoniums. After the main flush of flowers, trim them back lightly to keep them compact. They are tender, so keep them frost-free over winter and water sparingly until spring.
Please note there is a minimum order of 3 plants. All mail-order pelargoniums are grown and sent out in 6cm biodegradable fibre pots, which can be planted straight into compost without removing them. Roots grow naturally through the pot as it breaks down over time.
