Strange raspberry flowers
I have lots of summer raspberries in the garden. Usually the flowers are not very visible - looking green like the rest of the plant. This year however, on the same plant I discovered branches with beautiful white flowers (see first picture) and others with the usual green type of flowers (see second picture). As raspberries are not grafted, I was wondering how it is possible to get two different types of flowers on the same plant. Anyone any ideas?
