I am considering visiting Hillwood, Dumbarton Oaks and/or Tudor Place the last weekend of March to see flowering trees and spring bulbs. I think it is a bit early for many bulbs. Can anyone advise which gardens might have good displays? Also, I will be spending time on the mall (visiting the botanic garden and catching the orchid show among other things) and around the monuments. Are there any areas nearby with good early spring bulb displays? Thanks for your help, Tracy Fox
