Verbena 'Quartz Blue'

Garden Verbenas are a large group of hybrids, with mainly Verbena peruviana and Verbena platensis in their parentage. Verbenas are a major summer resource in Phoenix. They grow well in desert dry summer heat, they tend to get mildew in more humid weathers. They are good bedding and edge plant, in hot desert locations, they also make a good ground cover.

Culture:
If used as perennial, prune severely in winter

Propagation:
Sowing Verbenas in place is not very successful due to poor germination. Start seeds at 65°F to 80°F. When 8-week old, pinch to increase bushiness, and plant outside 12 inches apart (30 cm). Dead head spent flowers periodically, and fertilize occasionally.
