Cat Whiskers White is a member of the mint family, has an upright growth habit, and its tropical look with showy lavender blossoms make it a great addition to any garden paired with trailing and mounding plants, or can be great in containers. The exotic flowers stand above the plant’s shiny, dark-green leaves, and the color contrast sets off the flowers strikingly. Grows 3-4 feet tall, with an even wider spread. Blooms all summer in zones 9-10. These are growing in 3.5-inch, deep containers.
