For The Answer
Verbena x hybrida
Verbena x hybrida ‘Blue Princess' Blue Princess Verbena was originally purchased at the Royal Horticultural Society's Nursery at Wisley in England by Greg Grant while Director of Research and Development at Lone Star Growers in San Antonio. Blue Princess Verbena is a vigorous spreading type perennial verbena with a profusion of showy lavender-blue flowers on the new shoots. It has shown both increased heat and cold tolerance under Texas conditions. It can be hardy to zone 7b but like other perennial verbenas resents rapid temperature drops and cold wet soil. For best performance it requires full sun, good drainage and frequent shearings to about one foot. Ultimate spread can easily reach four feet. All verbenas grow and bloom best in the cooler temperatures of spring and fall and have a tendency to "bloom themselves out" during the summer. Propagation is relatively simple from cuttings and division. Blue Princess Verbena is a 1998 Texas A&M CEMAP promotion. In the near future look for white, pink, and purple forms to be available as well.
Name: Verbena x hybrida 'Blue Princess'
Editor's Notes: I picked this verbena up at the Royal
Horticulture Society's Nursery at Wisely, England while Director of
Research and Development for Lone Star Growers in 1995. It has since
turned out to be the top verbena in our Texas trials, providing both
improved heat and cold tolerance. In our extremely hot summers, it far
outperforms Homestead Purple.
