I could see how people could propagate from seeds of selected colored sugar snap pea plants for growing sweet peas, which are grown purely for their showy flowers.
This is the first year I've ever seen pea flowers any other color than white. And yes, they are sugar snap peas for sure.
Have a look-see.
Odd one out. A dark purple one.
Isn't this weird? Have you had mutant ninja pea flowers in your garden as well?
