Homeowner Growing Tips: These prolific bloomers need to be grown in good soil or fertilized regularly to give them energy necessary to create all that sweet nectar. Water regularly during hot and dry weather to prevent wilting. Removing spent flower spikes will encourage more new blooms. Mulch in winter in northern climates. In spring, cut back to a 12" framework to encourage sturdy, vigorous new growth.

    I bought this buddleia last spring from Romence Gardens and figured that I might get a bloom or two later this year. What a surprise to have it covered with blooms in late summer and fall! This is definitely the nicest buddleia I’ve ever had. Huge blooms in a medium purple. It’s already attracting comments from people walking by on the street. A great plant!

  • It's a Blue Winner!!

    The ButterFly Bush - a.k.a. Buddleia 'Grand Cascade' came well packed and in perfect condition. Since the arrival was just at the right time for planting - into my new garden it went. I love this bush. This was it's very first season and it grew beautiful blue cone shaped 'flowers'. I'm already looking forward to the second season. Thank you again.
