Monarda ‘Jacob Cline’

Jacob Cline Beebalm (Monarda Jacob Cline) is one of our most spectacular native Beebalm hybrids with heads of long tubular deep red flowers. Discovered in a Georgia garden, it has excellent mildew resistance and blooms for a month or so in mid-spring.

36-48″ tall x 36″ wide. With its spectacularly large, deep-red flowers, vigorous growth habit and mildew-resistant foliage, ‘Jacob Cline’ is a must for the perennial border. Planted into a compost-enriched soil with regular irrigation, this big boy will form impressive clumps that should be divided every 3rd year to keep it vigorous. Companion plant with Phlox paniculata ‘David’ for long-blooming summer color. (Cutting propagated.)

Sedum ‘Autumn Fire’

The border varieties of Stonecrop are a dependable choice for the late summer and fall garden, offering foliage interest earlier in the season, then a colourful display of flowers in the fall. This Canadian selection is an improvement on the older Autumn Joy, with a taller habit and stronger, less floppy stems. Plants begin to produce green broccoli-like buds in mid-summer, which gradually open into enormous dusty-rose flower heads, finally deepening to rich rusty-red during autumn. Even the dead flower heads have good winter effect. An outstanding cut flower, and also attractive to butterflies. Registered with COPF: royalty required for propagation.

sedum-fuldaglut-leaf-detail

Sedum ‘Fuldaglut’

Culture: Easily grown in acidic, average, dry to medium moisture, well-drained soils in full sun. Tolerates some light shade. Likes sandy or gravelly soils. Tolerates poor soils. Needs good soil drainage to perform well. Drought tolerant. Avoid overwatering. Plants may be sited 12” apart when grown as a ground cover. Easily propagated by cuttings or division. Plants spread easily (root where nodes touch the ground). Cut a leaf from a healthy sedum with about 1-2″ of stem and plant the stem with the leaf above soil. Plants are evergreen in warm winter climates.

Noteworthy Characteristics: Sedum spurium, commonly called Caucasian stonecrop or two row stonecrop, is a low-growing, sprawling, mat-forming sedum or stonecrop that is commonly grown as a ground cover. It is native to the Caucusus. This is an evergreen plant that typically rises only 3-6” tall but spreads to 18-24” wide by creeping, branching stems that easily root at the nodes. Thick, succulent, opposite, obovate, flattened leaves (to 1” long) with wedge-shaped bases are toothed near the ends. Leaves are medium green with reddish-tinged margins. Lower stem leaves are deciduous, but newer leaves near the stem tips are evergreen, typically turning deep burgundy in fall for overwintering. Leaves are arranged in two rows along the stems, hence the sometimes used common name of two row stonecrop. Tiny, 5-petaled, star-shaped, pinkish-red flowers (to 3/4” diameter) in dense, 4-branched inflorescences (to 4-6″ tall) bloom from late spring to mid-summer (June-July in St. Louis) atop upright reddish flower stems. Flowers are attractive to butterflies.

Genus name comes from the Latin word sedeo meaning to sit in reference to the general growing habit of many of the sedums (they sit and sprawl over rocks).

Specific epithet means false. Its use here is unclear.

‘Fuldaglut’ is a low-growing, mat-forming, maroon-leaved cultivar that grows 2-3” tall but spreads to 18” wide. Leaves are attractive throughout the growing season. Foliage is semi-evergreen in St. Louis winters.

Problems: No serious insect or disease problems. Slugs and snails may appear. Watch for scale.

Garden Uses: Rock garden or small area ground cover. Border fronts. Stone wall pockets. Sunny banks or slopes. Edging. Containers. Best when planted in groups or massed as a ground cover.

Heuchera ‘Palace Purple’

This selection was the first of many purple-leaved Coral Bells, and is still an excellent choice for towards the edge of the border, or in containers and tubs. Plants form a low mound of maple-shaped leaves, from bronzy-green to rich purple-red. Spikes of small creamy-white flowers appear in early summer. In hot summer areas a part shade location will help to prevent the leaf colour from fading. Evergreen in mild winter areas, but plants may be clipped hard in early spring. Division is not always easy, but can be attempted in spring. A former Perennial Plant of the Year for 1991

dicentra-spectablilis-flower-detail

Dicentra ‘spectabilis’

One of the most popular of old-fashioned garden plants, Bleeding Hearts burst into flower in late spring. Plants form a bushy, upright mound of light green foliage, with a somewhat ferny appearance. Dangling bright-pink locket flowers are held on arching stems, and these are excellent for cutting. Performs best in a rich, moist soil with partial shade, or at least protection from hot afternoon sun. After flowering, the plants should be sheared back to 6 inches tall, to rejuvenate the foliage. Even still, these often go completely dormant by midsummer, to return again the following spring. As an interesting sidenote, botanists have decided to change the name of the plant to Lamprocapnos spectabilis.

echinacea-pow-wow-wildberry-flower-detail

Echinacea ‘Pow Wow Wildberry’

Easily grown in average, dry to medium, well-drained soil in full sun to part shade. Best in full sun. An adaptable plant that is tolerant of drought, heat, humidity and poor soil. Divide clumps when they become overcrowded (about every 4 years). Plants usually rebloom without deadheading, however prompt removal of spent flowers improves general appearance. Freely self-seeds if at least some of the seed heads are left in place.

‘PowWow Wild Berry’ may be grown from seed, with flowers appearing in the first year about 20 weeks after sowing. In colder climates, start seed indoors in late January.

Echinacea purpurea, commonly called purple coneflower, is a coarse, rough-hairy, herbaceous perennial that is native to moist prairies, meadows and open woods of the central to southeastern United States (Ohio to Michigan to Iowa south to Louisiana and Georgia). It typically grows to 2-4′ tall. Showy daisy-like purple coneflowers (to 5″ diameter) bloom throughout summer atop stiff stems clad with coarse, ovate to broad-lanceolate, dark green leaves. Good fresh cut or dried flower. The dead flower stems will remain erect well into the winter, and if flower heads are not removed, the blackened cones may be visited by goldfinches or other birds that feed on the seeds.

Genus name of Echinacea comes from the Greek word echinos meaning hedgehog or sea-urchin in reference to the spiny center cone found on most flowers in the genus.

Specific epithet means purple.

POWWOW WILD BERRY is a purple coneflower that features large, deep rose-purple flowers in a floriferous bloom from late spring to late summer, sometimes with additional sporadic bloom until frost. It typically grows in an upright clump to 2-3′ tall and to 1-1.5′ wide on sturdy, well-branched stems that do not need staking. Each flower (to 3-4″ diameter) features downward-arching, overlapping, deep rose-purple rays which encircle a large orange-brown center cone. Narrow-ovate leaves (to 6” long) are medium green. POWWOW WILD BERRY is a 2010 All-America Selection (AAS) winner.

hemerocallis-chicago-fire-flower-detail

Hemerocallis ‘Chicago Fire’

Chicago Fire Daylily features bold ruby-red trumpet-shaped flowers with chartreuse throats at the ends of the stems from early to mid summer. The flowers are excellent for cutting. Its grassy leaves remain green in color throughout the season. The fruit is not ornamentally significant.

Chicago Fire Daylily is an herbaceous perennial with tall flower stalks held atop a low mound of foliage. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.

This is a relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season. It is a good choice for attracting butterflies and hummingbirds to your yard. It has no significant negative characteristics.

Chicago Fire Daylily is recommended for the following landscape applications:

  • Accent
  • Mass Planting
  • General Garden Use

Chicago Fire Daylily will grow to be about 24 inches tall at maturity extending to 3 feet tall with the flowers, with a spread of 24 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 18 inches apart. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years.

This plant does best in full sun to partial shade. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This particular variety is an interspecific hybrid. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

heuchera-georgia-peach-leaf-detail

Heuchera ‘Georgia Peach’

Heucheras are best grown in organically rich, humusy, medium moisture, well-drained soils in part shade. Parentage determines the best culture including optimum sun exposure. Unfortunately, the parentage of many hybrids in commerce today is unknown. Some hybrids will perform well in full sun, particularly in northern climates, but generally prefer some shade in the heat of the afternoon in southern locations. If grown in full sun, consistent moisture is very important. Scorch and general foliage decline may occur if soils are allowed to dry out. On the other hand, some hybrids perform well in shady locations, particularly if H. americana is a parent. Remove stems of faded flowers to encourage additional bloom. Foliage is essentially evergreen in warm winter climates. In cold winter climates such as St. Louis, the amount of retained foliage color in winter depends in large part upon the severity of the temperatures. A winter compost mulch applied after the ground freezes will help prevent root heaving. Divide clumps in spring every 3-4 years. Species plants may be grown from seed, but hybrids are usually divided in the garden.
