Hi, everyone, I'm quite new here. I need some ideas from you for a new tree to celebrate my son's birth. I plan to grow the tree in my southwest-facing front yard. I need it to be sun, disease and insects tolerant, without or with only white or yellow flowers, easy to care, and without fast-spreading roots. I do like flowering dogwood, but my neighbor already had one. Other options include saucer magnolia (white flowers), and Prunus serrulata. What else?
