Shade tree with small yellow flowers in north Texas
A pair of these are growing as shade trees in a courtyard of a medical facility north of Dallas, Texas. Ovate leaves, rough bark, and small yellow flowers that the bees seem to love. Looks natural, but may or may not be native to the area. First guess was Bois d'arc based on leaves, but bark and flowers don't seem right from my vague memories of last time I saw one up close. Apologies for the poor cellphone photo - no zoom and was trimmed too high for a closer shot. Familiar to anyone?
