What kind of tree is this, my mom doesn't even know and she's Pocahontas level amateur botanist
Your tree is a Psidium littorale, Cattley or Strawberry Guava. I am including a publication on this tree from UF/IFAS that will give you more detail on the Cattley Guava. http://edis.ifas.ufl.edu/pdffiles/ST/ST52900.pdf
Give your mom a break, in horticulture--the more we know, the more we need to know. Learning is never ending which is why horticulture is such an enjoyable hobby or occupation!
Let me know if you have further questions. Andy
