Lobelia

Cardinal Flower

In the dog days of August, just when the border is not looking so lively, this genus of colorful, stately selections rejuvenates the garden with spectacular leafy flowering spires, attracting crowds of eager hummingbirds. Perfect in meadow plantings, these sturdy herbaceous perennials appreciate a well drained site, a light winter mulching, rich, moist soils and partial shade in warm climates, except for Lobelia tupa and Lobelia laxiflora, which like it hot and on the dry side.

The lush tropical color scheme of this somewhat tender Chilean native is alluring. Cloaked in broad and pointed, pale green, felted foliage, each soaring, purple-tinged stem is crowned with a large, tapering raceme of warm brick-red blossoms. From the swollen base of each flower, a claw-like lower lip curls under and a tuft of gray stamens extends upward. A perennial of nearly monumental stature that likes it hot and on the dry side, Lobelia tupa can be associated with Melianthus, Muhlenbergia and Morina longifolia for a dynamic mélange of color and shape in the border.

Our featured plant: Cercidiphyllum japonicum

Cercidiphyllum japonicum: A tree brimming with elegance....

An inhabitant of China and Japan, Cercidiphyllum japonicum usually grows as a refined multitrunked tree with a pyramidal to rounded canopy. Cloaking gracefully structured branches, the lovely somewhat heart-shaped deciduous leaves unfurl in bronzy purple tones, and later exhibit medium bluish green hues for summer. The foliar grand finale includes brilliant yellow, apricot, orange or mauve colors plus a sweet strawberry-like scent that wafts some 15 feet or further on sunny, warm fall afternoons. This easy-care tree prefers adequate moisture as well as some protection from hot scorching sun and drying winds.

Autumnal Allure...

One of the greatest joys of gardening is witnessing the changes that occur in our landscapes throughout the year, and many deciduous woody plants pretty much top the list for affording dynamic seasonal transformations, especially in autumn. Most of the trees and shrubs featured in this newsletter are renowned for both their handsome habits and prismatic fall displays. We’ve also included a few of our favorite perennials that lend late season floral or foliar intrigue.

All of us Digging Dog plant wranglers wish you Happy Digging!
