Let me share with you some of the trees which are native to my city lahore (Pakistan) and blooming right now. These are Trees of Parkinsonia aculeata, Pterospermum acerifolium and Erythrina suberosa. First one is Parkinsonia aculeata also known as Vilayti kikar. It is a roadside tree covered in yellow flowers. It is also called Jerusalem thorn due to its thorny stems.
