LILIUM(LILY)Family: LILIACEAE
Of the recorded species belonging to this genus, most are native to three areas of the world: Europe, Asia and North America. Their culture depends in large part on their origin. Few can resist lilies in their garden for their magnificent flowers and ease of culture. Of the many ways of propagating lilies, seed is perhaps the best (if slowest) method of increase. Larger quantities may be raised in this way and unlike other methods of propagation, viral or fungal diseases that often affect lilies are not passed on.

Of the more than 90 species of lilies in the world, about half occur in China and Japan. Almost a third of the world total occur in the three provinces of Sichuan, Yunnan, and Xizang (Tibet) in China. This region is considered to be the major world center of distribution of the genus Lilium.

LYSIMACHIA minoricensisSummer2242
40cm
Endemic to Minorca in the Balearic Islands, this species was only known from a single location (Barranc de Sa Vall), where it disappeared between 1926 and 1950. Now entirely extinct in the wild and only found in cultivation and seedbanks. Attempts to re-introduce the species into its native habitat have been undertaken since 1959 but have been unsuccessful. Largely grown for its striking variegated foliage, small yellowish-green flowers appear in summer. This is a biennial which should self-sow to perpetuate; although it is likely a good idea to collect some of the seed to give to friends and seed exchanges in an attempt to keep it in cultivation. Likes a cool, shady spot.
