Arum Lily – strange and beautiful

The Arum Lily is a fascinating plant which stands out from the crowd throughout its life. The latin name is Arum maculatum but it has many old English names, the two most common being Lords and Ladies and Cuckoo Pint.

In the spring, the leaves unfurl, growing and turning out of the bare ground before most other plants are beginning to burst their buds.

From the cluster of lush dark-green heart-shaped leaves arises the flower, a creamy white wrap-around cone with a peaked tip. Within this white cowl – actually a bract rather than a flower – dwells the spadix which is a purple tower of tiny inflorescences.

Looking down into the centre of the flower from above gives a unique view reminiscent of a plasma ball, the looping tendrils creeping like electricity made visible.

The flowers die back and the leaves soon follow and you could all but forget about the lily through mid-summer. Then in late summer and early autumn, it asserts itself once more as the berries become apparent, growing from the spadix which is all that remains of the flower. These fruiting spikes are reminiscent more of a mushroom than a flower, appearing alone on a solitary leafless stalk where the berries soon shade from bright green to brighter red.

This is a fairly common species can be seen throughout the UK in hedgerow bases and woodlands. They are a plant of shady habits and often represent the only species where the darkness is densest under the closer canopies.
