Browallia is prized for its vividly colored blue flowers. It makes attractive plant if grown in hanging basket.
Germination Temperature (°F)
Water well when the surface of the compost feels dry.
Feed every 2 weeks with standard liquid fertilizer in Summer.
Browallia will normally be in a 5 inch pot and will not need re-potting. The plant is best discarded after flowering and new stock raised from seeds.
Sow seeds thinly in small pots of moistened seed compost.
Sow seeds in Autumn for Spring flowers, in Summer for Winter flowers and in early Spring for Summer flowers.
Browallia will take as much light as you can give it and needs good ventilation. The blooms will fade faster in higher temperatures, but the plant is susceptible to frost.
The taller varieties can be nipped back when they are young.
The dwarf cultivars such as 'Blue Troll' and the white-flowered, are best for windowsills. Greenfly and whitfly are sometimes a nuisance.
Scientists were able to revive a flowering plant from the fossilized fruit found in the stomach of an Arctic ground squirrel who was trapped in ice around 32,000 years ago.
