The Royal Horticultural Society has given this cutivar its coveted Award of Garden Merit. "Distinct. The best pink. Large well branched inflorescences. Good compact habit. Inflorescence size 30x8cm. Height and spread 240x250cm." http://apps.rhs.org.uk/planttrials/TrialReports/Buddleja 201...

This species is short-lived (usually under 10 years). Hard pruning (to 6") annually in early spring helps it renew itself and improves bloom.

All B. davdii cultivars require weekly deadheading for them to look and bloom its best.

Butterfly bushes may be good nectar sources for adult butterflies, but they are not food sources for the caterpillars of a... read more

This is a great bush, but give it lots of room if it is in an ideal environment. Mine is in full sun and I use drip irrigation. Starts to bloom in July and I keep it blooming by deadheading (cracking the spent panicles with my thumb) until late September. The first bloom is amazing, with very big panicles. Subsequent blooms aren't as big, but are definitely worth it to you, the butterflies, the bees and the hummingbirds. I cut mine down every year around St Patrick's Day. It gets very woody, so it likes rejuvenation. After the first year, I cut it down to about a foot and a half above the ground. After that, it has big woody branches, so I'm able to cut it two or three feet from the ground. The person above who planted it and expected it to be a be a fine blooming bush in a month or two sh... read more

Bought this plant early this past Spring and planted it immediately. It is now early Autumn and the plant still has done very little. It gets full sun and is watered regularly. Spikes of blooms have been very small, not fragrant and spindley. The entire plant has only grown about an inch all season. I plan on yanking it out of my garden and tossing it. Back home in Chicago we had them as kids and they grew profusely and attracked bees and butterflies, not here in Florida.

Love this bush. The flower spikes look so beautiful Today is a windy day and they are nodding in the breeze and the fragrance comes right into my home. I made sure I planted them so that when the wind blew I'd get the fragrance inside.

I think this is a very beautiful cultivar but I lost mine suddenly, I think due to excessive rains. I will get another one. I have 3-4 other cultivars that were totally unfazed by the rains, so I'm a little puzzled.

here, the bush is an evergreen shrub. it tries to grow during the winter, but only very slowly. we cut ours back every few years or so to keep it in control.

I just bought a butterfly bush yesterday, and I am not sure how to care for it. It's only about 1-2 1/2 feet. If you have any tips, PLEASE HELP!!! Greatly appreciated.

I love it! Beautiful!

I love the color and I try to keep it deadheaded at all times and pinched back for compactness.

Talk about drought resistance!!
I found a bush laying on the ground that hadn't been watered in 5 years other than by Mother Nature. It was alive, but somewhat shriveled, with broken limbs and very sparse. This bush has teeny tiny blooms (compared to these pictures) it is starving to death, but it is an exact duplicate to the picture of that majestic bloom in the picture. This one has found a loving home and I will do my best to bring it back to it's original beauty.

I love this butterfly bush! Mine is 12 ft and flowering now, and this morning I saw a swallowtail butterfly and hummingbird on it. Flowers are sweetly scented, it likes dry conditions w/a little water. Easy to grow and beautiful.

Buttrfly bushes are all pretty plants in my opinion....but this one is stunning!!! Gorgeous, soft pink flowers with an orange eye on spikes well over one foot long...and born in profusion!!! When cut back to 6"-12" in late winter - early spring, it can attain 10 ft by summer, with a beautiful shape!! I have several Buddliea, this is easily my favorite! And the fragrance....WOW!!!! A+++

Most butterfly bushes are hardy in zones 5 - 9. If you live in zone 5 or a colder zone, the tops in your butterfly bushes will likely die back over the winter. Even so, they will come back the next growing season bigger and better then before. Butterfly bushes prefer full sun (they must receive eight or more hours of sun a day to thrive). This cultivar can reach a height of up to 10'. It's pink flower spikes are stunningly beautiful.

The flower spikes are very beautiful on this cultivar. It should be cut to the ground every year to keep it in shape and size. Seeds do not come true.
