Senna Alata

The Candlestick Cassia gets its name from the large sprays of upright, fragrant yellow flowers that resemble candles, and in a similar way to the buddleia bush, it is a magnet for butterflies. A native to Central and South America, it makes a showy addition to any warm or well-protected garden, where it will bloom from spring to autumn, bearing large green leaves which fold up at night.
