Old-fashione sweet pea how authenticare they

摘要

A resurgence of interest in pre-1914 sweet peas has led to many reintroductions of historic cultivars.Roger Parsonslooks at their characteristics and assesses which ones are genuineRecent decades have seen renewed interest in growing - old-fashioned cultivars of sweet pea, Lathyrus odoratus. These were popular prior to 1914 but almost died out in the middle of the 20th century. But in the rush to 'rediscover' old-fashioned cultivars, how genuine are the cultivars being offered to gardeners? Growing these cultivars as part of a National Plant Collection of Lathyrus has led me to question the authenticity of some cultivars.
