Can someone please give me detailed info. on the differences between the Shamel ash and the Majestic Beauty ash? What I know : Shamels have seeds, MBs don't. MBs have bigger leaves and are maybe a little darker green. MBs keep leaves a little longer. Shamels have an egg shape that get wider as they get more mature. What I need to know: Do these 2 trees grow equally as fast? Do MBs get equally as tall and wide as Shamels? Are there any drawbacks to planting a MB vs. a shamel? Why aren't MBs as popular as Shamels? Given ample room for either tree, which one would you put in YOUR yard and why? THANKS!!!
