Lathyrus x hammettii - Colour Changing Sweet Peas!
The sweet peas you are used to growing are known by the botanical name of Lathyrus odoratus. Above, is 'Blue Shift' that belongs in the group of Lathyrus x hammettii. This exciting new hybrid is a major step forward in Sweet Pea breeding.
It is thanks to Dr Keith Hammett, who was the first person to successfully cross Sweet Pea species. Lathyrus x hammettii is a cross between Lathyrus belinensis and Lathyrus odoratus.
What is important to note with Lathyrus x hammettii is, its breeding can result in shifting genetics. I have noticed this with both Blue Shift and Porlock where some had different colouring.
I chatted to Dr Keith Hammett about this and this was his comment, "Still very early days with the Lathyrus x hammettii cultivars. Two distinct genomes settling down after the wedding."
So, don't be surprised if this happens when you grow Sweet Peas from this group.
