Another Good Shrub for Western Gardening

The silver fountain butterfly bush in the perennial garden is turning into a nice-sized specimen plant.

I wasn’t sure how many of my shrubs would make it through the winter, because the weather was so cold, so dry, and so windy.

It wasn’t clear to me until a few weeks ago what would leaf out and what would be chalked up to winter kill.

I was especially heartened to see my silver fountain butterfly bush (Buddleja alternifolia ‘Argentea’) was going to be blooming again this year.

Even though the shrub had quite a few dead branches that needed to be pruned away, there are still plenty to display the nice lavender flowers that call out to butterflies.

Plant Select recommended this butterfly bush in 1998 because it’s the only one that’s reliably shrubby in most of the U.S. and is good to Zone 4. The Denver Botanic Gardens has one of these shrubs in its xeric garden that’s grown to its full 15 feet tall and 12 feet wide. The purple blooms cascade down the branches for a fabulous display.

The butterfly bush in my landscape also lives up to its name and I’m looking forward to seeing what it attracts this year.
