Flower trees that can grow inside a "inner Courtyard"

I am building a house with an inner central courtyard which is open to the "Weather" from top. Would request advice on which are the types of flower bearing trees that can be accommodated in such a space. The floor space available is about 12 ft X 12 ft surrounded by internal walls of the house. The roots should not intrude too deep or branch sideways so as to cause damage to the walls of the house.
