This tends to disappear in warmer spring conditions. They contain no brown flecks. The leaf mark and flush pattern of York is similar to Dinninup and Goulburn, particularly in the early stages. The green colour shows the potential areas of use of York in Western Australia Seeds of York are black and relatively small, similar in size to Junee, smaller than Seaton Park and much smaller than Dalkeith. Seedlings of York tend to be smaller than Seaton Park.
Growth habit is moderately prostrate early in the season, but becomes more erect in spring.
The flowering time of York is very similar to Seaton Park. In Perth, both flower about 110 days after an early May sowing. This is about 13 days later than Dalkeith, four days earlier than Dinninup and 16 days earlier than Junee. This level of hard-seededness should enable it to persist more strongly when grown in rotation with crops.
