Verbenas offer a wide array of color choices for summer gardens, and 'Lascar Black Velvet' adds a deep, matte purple to the mix. This mounding, spreading variety will quickly grow to about a foot tall and a hair wider, so use this as a "filler-spiller" in container planters or hanging baskets, or add to sunny garden borders for a pop of color. Flower clusters are large and showy, catching the eye of passersby as well as bees and butterflies. Deadheading will keep new flowers coming and maintain a tidy look. Verbenas love the sun but require regular watering and fertilizing to last through until fall.
