Amaryllis is a single species of bulbous perennial - but nonetheless has some beautiful varieties from which to choose.
Amaryllis belladonna are autumn flowering, and will lighten up this time of year with its delicate colours.
Sometimes confused with Nerines - which are similar but different. Often referred to as Belladonna Lily, it is not a lily, nor is it a member of the lily family, but Amarilliaceae.
This bulbous plant is not the same as the indoor-grown Hippeastrum - though often mistakenly labelled as such. The Hippeastrum is a tender bulb, and from a different family even.
The Amaryllis pictured bears the name Amaryllis belladonna 'Pink Johannesburg'.

It is a delicate pink with contrasting dark stems. The foliage does not appear until after the plant has flowered. The foliage might benefit from some form of protection in exposed places, in order to protect it from frost damage. This would inhibit the bulb from strengthening up ready for the next year. Horticultural fleece will do the trick. If it is not in an exposed situation, then this is not necessary.
Amaryllis belladonna prefer a light but moist soil, but will also grow quite well in dry situations - especially if there is moisture in the autumn period. They are well suited to growing at the foot of a wall or in shrub borders where they will add a little different colour top the autumn hues.
They have numerous flowers on each stem - 4 - 6 or even more, and form small clumps over time. The flowers are borne at height of around 24in (50cm). A spectacular sight in the garden at this time of year.
