New Bristol Physostegias 
Among the Bristol introductions for 1938 are Sum¬ 
mer Glow and Rosy Spire, two new Physostegias which 
we believe will prove important border plants. 
The False Dragonheads are easy to grow, bloom 
over a long period, and are perfectly hardy. Both of 
these new varieties are a result of crossing the tall P. 
speciosa gigantea with the dwarf garden variety, Vivid. 
Summer Glow is the taller of the two, often exceeding 
4 feet, with flowers of a rosy crimson color that is 
very attractive. The other variety, Rosy Spire, is the 
one pictured here in color. It is not quite so tall, 
averaging from 3 to 33^ feet, and is a shade deeper 
in color.
