Plant details

Although their stiff evergreen rosettes are part of the scene in hot dry Central and North American scrublands, yuccas are hardier than they appear, and only fail in cold exposed inland positions, where they are better grown as container plants. Otherwise they are handsome architectural foliage plants for dry, sunny borders and gardens by the sea. This species makes dense clumps of stiff leaves 75cm (30in) or so long and edged with fine curly hairs. The remarkable flower-spikes, 1.8m (6ft) or more high, appear when plants are five or more years old. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).

Reader reviews


I have something similar to this plant in my front garden. During the last month a stalk has come up from the middle of the plant and I have loads of white bell shaped flowers on it. I've had the plant for eight or nine years growing in the same place and its the first year it has flowered.

My question is can you tell me if this plant is a danger to the foundations of my house?

Thank you
