Buddleia 'Ellen's Blue' BUTTERFLY BUSH Dec (z5) (Bfly,Cut,Fra)
Large clusters (a bouquet all by themselves!) of some of the deepest, truest blue Buddleia flowers are complemented by the handsome grey-green foliage of this 5-6'shrub. Sun/Med

Love the color! I got this for the first time this Summer and the BF's love it too! Of all my Butterfly Bushes (have about a doz. different ones), this one is the one they flock to most of the time! I try a keep my Butterfly Bushes deadheaded for them and also to keep them blooming for me. I keep most of the Bushes pinched back so they stay more compact.

I just read today (11/20/06) that the flowers get bluer the bigger it gets, so I try not to pinch it back next year. Interesting.

'Ellen's Blue' is a really nice probably hybrid buddleia, well-behaved, and with that soft medium blue that's so wonderful in any garden. It is very fragrant, and a butterfly favorite. I planted it nearly a year ago, and it is 4' tall and a bit wider after light pruning a month ago, just removing old blooms. Buddleias tend to be shorter-lived down here in central Florida, so I am interested to see how long this one will stay. I have only grown B. daividii before. Wish me luck!
