Stage 1 of the mystery is solved! One of my mystery peas has flowered and is now producing its very first pod.. beautiful lilac petals and then a lemony-yellow pod! Many thanks to Rebsie at Daugher of the Soil for identifying it as Golden Sweet.. its colourful and beautiful, as well as historical, and I am looking forward to tasting my very first homegrown peas.
Now for stage 2! A second pea plant has a stunning first flower.. a really beautiful two-tone purple bloom.
I'm thinking this one might be purple-podded.. I will be checking regularly to see!
