Currently my only flowers...
My favorite tree is the Catalpa tree I have right next to my driveway here in town. It's very temperamental and every year I think it's dead because it doesn't get leaves until at least June. It blooms only occasionally, which is why I quickly took a picture. The scent is extremely "heavy" and sweet, almost overwhelming. When the flowers are gone, the tree gets long pods, like a vanilla bean pod but about 4 or 5 times as long.
I ought to do a little research, this tree has never grown much, never gets tall. It grows weird and crooked, reminding me of a bonsai for some reason.
