Peace lilies are not true lilies, but members of the Araceae plant family. They make great indoor plants because of their ability to remove toxins from and purify the surrounding air.

Green flowers are quite unusual in the plant world, but this green lily, photographed by Janet, is very beautiful. 

Spathiphyllum floribundum is also known as the Snow flower or Peace lily.  The true flowers are formed in the centre column (the spadix) and protected by the green outer sheath, known as the spathe.

Flower of the Week - Lily - Arum lily by Georgie

This weeks flower will be the Lily, starting with the Arum lily (Zantedeschia aethiopica) photographed in Perth, Western Australia by Georgie.

Arum lilies, originally from Southern Africa are popular garden plants, and commonly used in floristry. Unfortunately these plants are toxic to humans and animals if ingested, and have been declared an environmental weed in many parts of Australia.

Keep cats away from all lilies, as cats are particularly susceptible to lily poisoning - even ingesting tiny amounts of pollen can be fatal.
