Gardeners' Notes:


On Aug 4, 2015, Rickwebb from Downingtown, PA wrote:

This cultivar is not sold and planted as much as the all pink 'Anthony Waterer' or the yellow foliaged 'Gold Fame' or 'Gold Mound', all of which are so abundantly planted. It is occasionally found in Midwestern and Eastern yards and landscapes. Some strains, depending on where they cut the soft wood cuttings, produce more white flower clusters than pink ones and visa versa. Some are about equal as they should be. Best to buy them when in bloom to see what one likes.

I have this shrub in a mixed flower bed----for variety and interest. My favorite things about this plant are: It adds a delicate form to the garden's bolder plants like roses, lilies, phlox, etc. It's a "cloud" of continuous blooming fluff with both pink and white blooms. My shrub has by far and way more white blooms than pink, but I've seen the opposite. It doesn't reseed like my other spireas. I cut it down to 1 foot in the fall and it seems to thrive on the abuse by growing and blooming even bigger and better the next year! Even after a sharp shaving of all the brown flowers, I thought it was done for the year but to my surprise it quickly popped out enough blooms to make a show. Never needs staking. The cons are few: Not enough combination of pink and white blooms; dead-head... read more

My grandmother was growing this at her home 50 years ago. It bloomed even on the north side of her house, but will do better with more sun. Our church gardens include one as well. All these Japanese Spireas make a much better show if cut back hard every year or so.

I read above where this plant is considered sterile or doen't come true to seed. I guess I am confused, as I have grown this several times from seed. The seeds come from my parents plant, that I raid at least once a summer. Does anyone have anymore info on this?

Easy to grow even in poor soil. Spent blooms turn brown and ragged-looking but if pruned off will bloom again later in summer.

Low maintenance plant. The bees and butterflies love it. The blooms look like a little like Queen Anne's Lace, but the bush we have has pink blooms on it.

Dwarf, mounded, deciduous, pest-free shrub makes an excellent low hedge, edging or border. Foliage is bright green. White, pink and red bloom clusters cover the stems late spring to fall. Tolerates high summer and low winter temperatures.
