On Tour Today - Just Opening

As you stroll through the garden today, your head will undoubtedly turn toward the stands of deep red Hemerocallis 'Chicago Apache' (Daylily) in the Light Plate or to the many species of Echinacea purpurea (Coneflower) in shades of pink, orange and greenish white. You might want to photograph the 4-foot tall, lavender blue Perovskia 'Little Spire' (Russian Sage) mixed with bold, silvery Eryngium yuccifolium (Rattlesnake Master). But if you take a closer look, you will find plants that are just beginning to open for their August showing.

In the Dark Plate, near the middle of the south path, Scutellaria incana (Hoary Skullcap) is just beginning to show its lavender blue flowers on loosely branched 3-inch spikes. Another member of the mint family, this native makes soft mounds 3 feet high that will continue blooming into September. Small white hairs on its square stems give it the "hoary" description to its name. When dry, its seed head looks like a tiny helmet or skullcap. Directly behind this grouping is a subtle plant, Salvia glutinosa (Sticky Sage). Its similar mound shape and pale yellow flowers make it a good companion for the skullcap.

At the top of the north stairs and overlooking the Seam, Helelnium autumnale 'Rubinzwerg' (Sneezeweed) is opening its daisy-like flowers that are the color of roasted tomatoes with darker centers. This North American native is a member of the aster family and can grow to four feet. Its common name was given because its stamen parts were used as an ingredient in snuff, not because it was an allergen. Currently, two ornamental grasses are neighbors to the sneezeweed - Sporobolis heterolepis 'Tara' (Prairie Dropseed) and Molinia litoralis 'Transparent' (Moor Grass).

A dozen garden signs will be out identifying Agastache 'Blue Fortune' (Giant Hyssop), Liatris spicata (Blazing Star) and Silphium laciniatum (Compass Plant) among others. Free tours are offered from 10 am to 1:30 pm and last about 20 minutes.

What's Blooming? Color!

While the violet-blues of the Salvia River continue to dominate, other plants are bringing more colors from the spectrum as the garden eases into its summer cloak. Reds, oranges and yellows can be found, making an effective contrast to the blues and purples of the meadow sage.

In the Light Plate, Echinacea 'Orange Meadowbrite' (Coneflower) can be found between the Salvia River and the Seam, growing through the delicate blades of an ornamental grass, Molinia caerulea 'Dauerstrahl' (Moor Grass). Look for Monarch butterflies lighting on the dark cones as they continue their migration through Illinois.

Above the Seam in the transition area of the Dark Plate, Knautia macedonica (Knautia) is opening before its companion plant, a daylily, Hemerocallis 'Gentle Shepherd' that will follow next month. If you are familiar with the lavender perennial pincushion flower (Scabiosa), you will see some similarities as they are both from the same family, Dipsacaceae. However, the flower of the knautia is claret red and only an inch across. As you traverse the stairs, notice that the red of the knautia echoes the color of the burnette on the opposite side.

The tallest plant in the Meadow is in bloom with bright yellow daisy-like flowers. Silphium laciniatum is commonly called Compass Plant because it can align its leaves north and south to reduce exposure to the hot sun and conserve moisture. This North American native can grow to 10 feet, towering above the Rattlesnake Masters and Green Edge Coneflowers that are interplanted throughout the Meadow. Beginning in late summer, the seeds of its cones will feed birds through the fall and into winter. Look for goldfinches perched along its stem, looking for food.
