Cardiocrinum giganteum.

Whilst we were clearing the Dell of leaves yesterday, Ruth was telling me of the most beloved plants at Bodnant. One is the Cardiocrinum giganteum, which she told me takes seven years to reach the point of flowering. I am now at home gazing at pictures ~ it truly is stunning. The Cardiocrinum giganteum comes from the Himalayas, yet it looks like it comes fresh from 'the Lord of the Rings' or another otherworldly dream. Seven years of patience, a beautiful bloom and then death, there is something deeply poetic about this plant.

Cardiocrinum giganteum, "Himalayan Lily".
(Monocarpic perennial.)

Planting: February to July. Moist but well-drained soil.
Flowering: June to July, after seven years.
                        Monocarpic (dies afterwards).
Aspect: Partial shade, sheltered.
Hardiness: Fairly hardy.

Notes: The cardio of its name is derived from the heart-shaped leaves it produces.
               Giganteum is an equally apt title, given it can reach up to ten foot in height!
