Yellow Flame of the Forest
Butea monosperma var. lutea is commonly known as the yellow flame of the forest .It is a medium-sized dry season-deciduous tree growing to 49 ft tall but taller than well-known Butea monosperma. The leaves are pinnate, with an 8-16 cm petiole and three leaflets, each leaflet 10-20 cm long. It is seen in all its ugliness in December and January when most of the leaves fall: but from January to March
Butea monosperma var. lutea possess charismatic ivory-white flower buds and bright yellow flowers covering the entire crown. These flowers, which are scentless, are massed along the ends of the stalks--dark velvety green like the cup-shaped calices--and the brilliance of the stiff, bright flowers is shown off to perfection by this deep, contrasting colour. Each flower consists of five petals comprising one standard, two smaller wings and a very curved beak-shaped keel.
Butea Monosperma prefers a sunny position, though they also thrive with some shade. Heavy shade depresses growth. They require moderate watering. These plants can tolerate some frost, though they are usually defoliated by it. They grow best on old alluvial soils and weathered red basalts. however, it succeeds on a wide variety of soils including shallow, gravelly sites, black cotton soil, clay loams, and even saline or waterlogged soils where few other trees will grow.
It is used as an ornamental plant in the gardening.
