The flowers of spider lilies emerge on bare stems between August and September. Named spider lily because of its long arched stamens, which resemble spiders legs, these flowers are exotic and bold, perfect for a late summer border.
Spider lilies are in the genus Lycoris, and are not actually lilies but part of the amaryllis family. They are planted in the same way as amaryllis, with the top of the bulb left exposed, and will grow to around 45-70cm tall. There are 25 species, which originate from East Asian countries including Nepal, China and Japan. Of these 25 species, the ones easily available to buy in the UK include red spider lily, Lycoris radiata, which is a striking scarlet species and golden spider lily, Lycoris aurea, with golden yellow flowers. Others such as Lycoris squamigera, the electric blue spider lily, are more likely to be found in the USA.
In Japan spider lilies are known as higanbana because of their use as a memorial flower during higan. Higan is a celebration centred around the autumn equinox, when Buddhists in Japan pay their respects at burial sites. The spider lily is often used as a symbol in Japanese books and films to foreshadow death.
For plant lovers the spider lily is prized for its colourful displays and it can be seen growing en masse in Japanese parks. In the UK, these colourful flowers can be grown in containers or sheltered borders and are a source of nectar for pollinators. All part of the plant are toxic and should be kept out of reach of children and pets.

The bulbs should be planted so that top of the bulb is exposed. Plant each bulb 10-15cm apart in April to May for autumn flowers. Cover with fleece if late frost is forecast. Water well once planted.
