Two New Varieties of Katie's Dwarf Ruellia
By Don Miller, North Haven Gardens Horticulturist

 

Primrose       
       Lots of gardeners are familiar with the hardy perennial Ruellia brittoniana “Katie’s Dwarf.” This is a dwarf variety of the 3-4 ft. tall Mexican species that has naturalized in the southeast United States. Katie’s Dwarf only gets 8-10” tall. It has become popular as a border plant or ground cover for small areas. It makes a great spot of perennial color in the summer garden. Commonly called Mexican Petunia, it blooms all summer with zinc blue-purple trumpet-shaped flowers that close up in the afternoon.
      Now there are two new colors of this favorite perennial. The pink one goes by several names in the nursery trade: ‘Bonita,’ ‘Colobe,’ ‘Poquito Pink,’ or simply ‘Katie’s Pink.’ The white cultivar has several names. It is known as ‘White Ruffles’ or ‘Katie’s White.’ All three of these colorful perennials will thrive in our Dallas-hot sun or grow in light shade. They will also tolerate different degrees of moisture in the soil. They will grow in wet soil and also tolerate quite dry conditions. These perennials would be beautiful mixed or in solid clumps of color. They could also be used in a border alternating the colors.
      So, if you are looking for a short, heat tolerant perennial that will bloom all summer and tolerate excess water or some shade, this would be your answer.

     
Local Dallas Rosarian, Field Roebuck, has just published “Foolproof Guide to Growing Roses.” This is a great Metroplex rose garden resource (160 pages). You might want to add Rose Garden: A Journal, which has pages for notes along with great rose information.
