|It's really difficult to identify a tree based upon someone else's observations, but I'll give it a try. Prunus 'Okame' - One of the earliest of the flowering cherries, its carmine-pink petals, with rose-red calyx and reddish flower stalks, open fully before leaf break. It has very consistent year-to-year blooming. The rosy red buds are attractive before flower break, and the calyx and reddish stamens persist for a week after flowering. The overall floral effect lasts 2 to 3 weeks. |

Cassia leptophylla is variable in growth habit and some years it flowers more than others. Here's a website with photos of flower clusters on a mature tree. Compare this to what you saw - perhaps it is a match. If not, submit a new question with lots of details and we'll see if we can identify it for you:
