Citrus Switrus Ichangensis

Cold tolerant down to -15°C

Switrus Ichangensis also known as Ichang Papeda, is probably one of the most winter hardy and frost-hardy evergreen citrus species, withstanding temperatures down to -15°C.

Lubera grows it in Buchs, Switzerland and decided to name it Switrus Ichangensis.

Originating from mainly central and southwest China at altitudes up to 2400 metres, citrus Ichangensis is one of the best citrus plants for outdoor growing.

In the past, many varieties have been bred and crossed with Ichang papeda.

It has good resistance characteristics and is used as a rootstock to provide colder resistant hybrids such as the Ichangqaut or the Ichandrin (kumquat and mandarin orange hybrids).

  • Flowers/Fruits: The flowers exude have an intense scent. The medium-sized fruits have a rough, usually greenish peel, which can also lighten up a bit when ripe. The peel is thick and full of essential oils, some of which are also used for perfumes.
  • Maturity/Harvest: Autumn or spring.
  • Flavour: Ichang papedas have little juice and are relatively full of very large, mono-embryonic seeds. The taste is very sour, with bitter notes; the fully aromatic, thick peel offers potential in the kitchen.
  • Price: A bush in a 5-litre pot £37.40, for details visit www.lubera.co.uk.
