Copper Fennel

Smokey bronze finely dissected leaves are ornamental throughout the growing season on this culinary herb with the flavor of anise. Large flat umbels of small yellow flowers appear in July and August and are attractive to a number of pollinator insects. All parts of the plant are edible (the swollen bulb cooked, the leaves and stems as additives to casseroles, and the flowers as flavorings). This is a short lived perennial that should be planted in a sunny location.

Gemo Dense St. Johnswort

Dense St. Johnswort is a Danish cultivar whose showy golden blooms flower from July through September—much longer than other Hypericum. One of the parents of this cultivar, Hypericum kalmianum, is endemic to the Great Lakes region of the United States. This low-maintenance perennial forms a tightly branched, mounded shrub with dark green, willow-like leaves and grows to 30 inches by 30 inches. It requires moderately fertile, evenly moist soil, and once established, it is relatively drought tolerant.

This is not the species valued for its medicinal properties (H. perforatum). St. Johnswort is poisonous to livestock when ingested, and in high doses, it can cause many of the same symptoms in humans.

St. Johnswort is one of the few plants tolerant of being planted near black walnut trees. Soil under these trees tends to be alkaline, influencing the growth of many plants. These trees produce a nontoxic, colorless chemical called hydrojuglone, which kills many plants as they take up the chemical from the soil.

Short-toothed Mt. Mint

Pinkish white flowers in dense spikes just above the silvery green foliage are loaded with nectar, attracting a large number of pollinator insects. Plant in full to partial sunny locations in moisture retentive soils and allow room for the plant to moderately spread by rhizomes over the years. Late summer these plants are swarmed by an incredible number of pollinator insects visiting the nectar loaded flowers. The bruised leaves give off a strong mint fragrance.

Summer Beauty Ornamental Onion

Allium tanguticum 'Summer Beauty', forms a clump 12 inches wide. It blooms in mid-summer with pale lavender pink, 2-inch globes that sit atop 24-inch stems. It prefers well-drained, loamy soil in full sun. Summer Beauty is a butterfly and honeybee magnet.

Summer Beauty ornamental globe onion is sometimes referred to in the literature as Summer Beauty lavender globe lily—but it is not a lily at all.

Thomas Edison Decorative Dahlia
Some cultivars stand the test of time. Thomas Edison was introduced to horticulture in 1929 and remains a favorite of gardeners world wide. Deep purple petals are arranged in an informal decorative style flower and appear in late July with flowering continuing up to the first heavy frosts of fall. Pollinators are drawn to the flowers and seed eating songbirds will gladly gather to feast upon the ripened seeds in fall.
Virgin's Bower
Virgin's bower is a sprawling vine that is well adapted to support from a wall or large shrub in the garden. Blooming during the dog days of summer with frothy masses of small white flowers, it continues to provide ornamental interest with feathery fruits that appear in fall and persist well into winter.
