Netherlands (Zone 8b) wrote:

Hesperis is a vigorous hybrid phlox cultivar. It flowers over a long (July to October) bloom period with conical clusters of small, lilac, heavily fragrant flowers that sit on straight, stiff stems. Aptly named as the flowers resemble those of Sweet Rocket or Dame's Rocket (Hesperis matronalis).

Phlox 'Hesperis' probably is an x arendsii hybrid. Arendsii hybrids are crosses between Phlox paniculata and Phlox divaricata, and are noted for having the attractive flowers of the former combined with the compact form of the latter.

Hybridized by Coen Janssen and introduced in 2000.
