A unique, independent British seed company

Allium Seeds is the only UK-owned company breeding bulb onion & shallot varieties for the professional market.

Allium Seeds is the leading supplier of onion sets, seed shallots and echalions to the UK market.

Predominantly, we supply our own varieties, which have been bred in the UK, specifically for our customers.

Our seed range includes open-pollinated and hybrid red bulb varieties, the only UK-bred hybrid shallot varieties, echalions, and other specialities.

Bred in-house from first crossing to commercial seed production

Because of our in-house breeding team, we have control from the very first crossing through to commercial seed production.

Our expert team provides guidance and support to our seed production partners to maintain quality at every step. All seed lots are grown in our trials and carefully checked by our breeders to ensure varietal purity.

Onion set development

Sets are produced chiefly on virgin fields in France with inspection by NAKT in Holland and GEVES in France. Some production continues in Holland.

Our seeds are fully tested for freedom from stem and bulb eelworm (Ditylenchus dipsaci), and our production fields are certified free from white rot (Stromatinia cepivora).

All fields are inspected regularly by Allium Seeds staff as well as NAKT. We are constantly checking for the trueness of varieties.

With written approval of fields by NAKT, valid as a plant passport under directive 2000/29/EU. We provide full traceability using NAKT numbered field labels attached to bags. With certification at harvest time for freedom of downy mildew (Peronospora destructor).

Our personalised approach to delivering dependable service has earned us many long-term relationships. Trust us to exceed your expectations with our attention to detail.

Because of our in-house breeding team, we have control from the very first crossing through to commercial seed production.

Our breeding has produced market-leading set varieties – over winter variety Shakespeare and spring-planted Rumba and Griffon as well as the early maturing hybrids such as Red Radiant. We have a range of very long-day reds, which started with the open-pollinated variety Garnet and has recently produced Red Herald F1. We have a shallot breeding programme that has produced several hybrids, including the widely used round variety Lorient F1. A wide range of new material is in the pipeline to add to the success.
