Another question: if it's the MFR ones what type do you have? The standard, mega, sacred or glowing sacred? If it's the normal then see above. If it's the others you REALLY don't want them growing in your base.
It could be cool for an overgrown forest base... and the forest is just 1 treeNo, no, no. You want to plant the Super Utra Mega Glowing Rubber Tree of Server Annihilation directly in the center of your Server Admins' ME room. Add bonemeal. Leave the country and assume a new identity.
Seriously, who thought those things were a good idea, anyway?
There is a huge difference between Endor Forest and the Super Ultra Mega Glowing Sacred Rubber Tree of Server Annihilation. It has the power to literally destroy the playability of your world. It will generally crash your world when it grows, due to the number of blocks being generated as well as the huge update to lighting effects. It can bring strong servers to their knees.
Honestly, having one to play in as a tree of life style base would be fun once, but if you should grow one without knowing what it was, you can kiss your world goodbye.
