Poor Knights Lily is a stunning plant and well worth growing. A very slow growing plant with fans of flax-like leaves up to 1m high. Its striking red flowers occur on tall stems in Spring but it takes up to 7 years to flower. When root-bound it will flower more quickly and prolifically.

On the islands, the plants are fed with seabird droppings, which are high in nitrogen and phosphorous. You can simulate this with bird guano, which is sold at some garden shops, or online. Or you may use any slow-release fertilizer that is rich in nitrogen and phosphorous.
