Excellent variant of Erythronium sibiricum known only from limited area around its locus classicus. It was published by me as subspecies of E. sibiricum, but after checking of DNA its status was rised to species level by Russian botanists. The main difference between both are in colour of anthers: in E. sulevii they are black whilst in typical E. sibiricum, - yellow. Extremely rare and offered only by me. Very limited stock.
