Yucca elephantipes

These bold, striking plants with their sword-like long green leaves growing out of a trunk never fail to impress. They are one of the few houseplants that really do love the sun, so ideal as that stand-alone specimen for the conservatory. Grown for its foliage and shape, it can have white bell-shaped, scented flowers but this is rare.
Place in a sunny spot, although it will take some shade. It is quite tolerant of temperature in the home but don’t let it fall below 7°C. Water more often in the summer, feeling the top of the soil before you water, and reduce the watering through the winter months.
