Leeks were sown at the beginning of 2018, and harvested on the 7th November. Plant descriptor data were collected on the 8th November, following a night out of the ground, and stored in the UKVGB. Data were collected on 2-9 plants depending on the number that grew, and the variability of the accession. Descriptors were scored following the guidance found in the document "Descriptors for Allium species". Citation: IPGRI, ECP/GR, AVRDC. 2001. Descriptors for Allium (Allium spp.).
