Gardeners' Notes:

Positive coriaceous On Jul 16, 2014, coriaceous from ROSLINDALE, MA wrote:

This is reasonably resistant to black spot even here on the east coast (Boston Z6a)---without spraying, only about the lowest 12" defoliates. It's vigorous and upright, often reaching 6' tall in a season (after having been pruned back to 18" in the spring.) I wouldn't recommend spacing it closer than 3'.

Floriferous, and quick to rebloom. Virtually no fragrance. Flower is a good color echo for Crepe myrtle 'Hopi'.

Easy to grow, quickly repeats. The simple, clear pink blooms remind me of dogwood blossoms. I planted a single Betty Prior in a side garden last year and liked it so much I put in 3 more by my front door this spring.
