|First flowers of male Ginkgo biliba tree. 4.7.16|
I've often thought it will have a better chance of surviving our moving away, if the tree is male. Female ginkgos have fruits that many people object to, because they are stinky. The males are nicely suitable for picky people, because they have no stinky fruits.
The male flowers are sort of a catkin. The female flowers have a swollen terminal aspect that becomes the seed.
