Barleria Cristata: Features

• B. cristata is a perennial shrub that can grow up to 4 feet in height. 
• The stems are terete and branching, and they are coated with delicate trichomes.
• The corolla is purplish blue in colour and ranges in length from 4.5 to 6.5 centimetres. 
• The tube is first narrowly cylindrical and then progressively widens. The lobes are oblong-elliptic in shape and measure roughly 1.5 centimetres each. 
• Stamens are four in number and are didynamous; the filaments are pilose, particularly at the base, and the staminode has one filament that is sparsely pilose. 
• The ovary is oblong-ellipsoid and hairless; the style is linear and about 2.5 centimetres long and also hairless; the stigma is somewhat swollen. 
• Capsule 1.2-1.8 cm in length, glabrous, and containing four seeds. Seeds subglobose to oval, 4-5 × 4 mm.

Barleria cristata: Growing tips

• Barleria cristata should be planted in a section of the garden that gets either full sun or a combination of sun and moderate shade. 
• This plant does well in soils that drain well and can survive periods of drought. 
• Every spring, prune the Philippine violet right down to the ground in order to keep it looking bushy.
• The plant does best in soils that are dry to medium in moisture, have good drainage, and may get full sun to partial shade. 
• Occasional doses of fertiliser can result in bigger and longer-lasting flowers, which can last from September until frost.

Barleria cristata: Maintenance tips

• It is necessary to maintain the bush in its current structure. 
• A severe cutting back of the shoots is required either immediately after the flowers have finished blooming or in the early spring. 
• You may leave the twigs between 5 and 10 centimetres long. 
• However, the plant is not pruned back completely until the fall since buds only develop on the new growth of the previous year’s branches, and if they are pruned too frequently, they will not have time to form.

Barleria cristata: Uses

• The Thai people have traditionally relied on this plant as a form of herbal medicine. 
• According to some accounts, it can also function as a blood purifier and a diuretic. 
• Since it blooms in December, people in South India refer to it as the December Flower. These flowers are typically strung together to make flower garlands, which ladies then wear in their hair. 
• The blossoms are referred to as December Poo in Tamil and Decembaralu in Telugu. Both names come from the month of December.
