Verbena lilacina 'De La Mina' - Inland Valley Garden Planner

Image Gallery

Description

In recent years the Lilac verbena has become widely recognized for being a premier butterfly attracting plant for gardens throughout the Inland Empire. Part of this is due to its long flowering cycle from spring into summer. Native to Cedros Island off Baja California, it grows into a loosely mounding perennial, 2-3 ft. tall and as wide.

One cultivar, V. l. 'De La Mina' is a popular cultivar due to its very uniform shape and deeper purple flowers. It grows best in sunny exposures, adapts to a variety of soil types with good drainage and can be clipped in fall to manage size and shape.

Water Needs

Lilac verbena and its cultivars grow well in Inland Empire gardens in areas of full sun and with low amounts of supplemental water. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. As shown in the chart below, there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water and you should make irrigation adjustments based on field observations of growth and character.
