October's Peak Performers

The autumn season in Southeastern Wisconsin is usually pleasant and pretty… but the interesting color hues are usually attributed to a variety of hardwoods that thrive here.

Sugar maples, as well as a variety of maple cultivars, contribute to the fall landscape along with deep red sumac, oaks and an assortment of trees.
With all those trees donning their fall wardrobe, it might be easy to overlook other plantings in our autumn landscape.  Shrubs, perennials and annuals contribute color and texture at eye level and ground level; these plantings are also peak performers during October.  A few of my personal favorites:

In the shrub category, I’m impressed with blooms on Hydrangea paniculata ‘Bobo’ which is pictured here.  The genus Hydrangea has a variety of offerings for your enjoyment during autumn:  ‘Pinky Winky,’ ‘White Diamonds,’ ‘Little Limelight.’   Each cultivar produces white or light blooms during summer, but the dramatic colors arrive in autumn (shades of pink, burgundy, green, tan).   Dried blooms can be incorporated into floral arrangements as well—with or without a wisp of spray paint on the blooms!

In the perennial category, an obvious autumn charmer is Sedum ‘Autumn Joy’ stonecrop. This plant is monochromatic during summer—usually a light green— but the stems are sturdy and support developing flower heads.  When fall arrives, the deep pinkish blooms appear and mature to a copper color.   Although I grow a few types of tall sedum, ‘Autumn Joy’ is my favorite during October.

In the annuals category, I can’t resist these dainty ornamental peppers called Capsicum annuum ‘Twilight.’  After purchasing seeds in New Mexico and planting those seeds in early MAY, I was impressed with their performance all summer long.  They formed tiny upright peppers in early JULY, which were purple and pretty!  Later, purple faded and red-orange colorants emerged; ‘Twilight’ provides a spark of color in the autumn landscape.  (After these peppers die from frost, I will toss them under our shrubs to deter critters from munching on stems during winter.  ‘Twilight’ is rated higher than 30,000 units on the Scoville heat scale.)
