'Galfrey Lye' is one of those that I bought and believed for a long time was a mistake. It was stringy with thin branches. So I stuck it in a far corner. I liked the little white and ruby flowers, but it wasn't until it grew up into my cherry trees that I realized how beautiful it could be.
All it needed was some pruning to grow a strong trunk. Which is now has as a four foot high bush without the need for cherry branches to support bunches of these little delights. But those branches that did grow up into the cherry trees get to stay there, for reasons I am sure you can see.
