'Honorine Jobert' is a vigorous, fibrous-rooted, compact Japanese anemone hybrid which typically grows 3-4' tall, spreading by creeping rhizomes. It bears single white flowers (2-3" across) with yellow centers on graceful, wiry stems over attractive dark green foliage mounds. This great cultivar was first discovered in the garden of its namesake M. Jobert in Verdun, France, in 1858. It has been highly popular in European gardens ever since and remains the most popular and highly sought after white anemone today. It is quite floriferous and flowers from August to late September.

'Biokovo' geranium is a real attention getter, sporting white blooms with bright pink stamens that lend the flowers an overall pink blush. Not only do the masses of flowers attract attention, it keeps blooming for four weeks or more in early to mid-summer (and on occasion, re-blooms in the fall). Bees, butterflies and other pollinators can't get enough of the blooms, and the leaves offer up shades of scarlet, orange and bronze in the fall.
The plant is compact, low to the ground, forming a moderately fast growing groundcover, up to three feet in diameter. It spreads by shallow, somewhat fleshy rhizomes (underground stems) that are easy to pull to control its spread. The leaves are medium green, slightly glossy, lobed and fragrant. They are also semi-evergreen, adding some early color to the garden.
Capable of full sun or part shade, it is a very adaptable, long-lived perennial that can be grown in borders (at the front), rock gardens or containers. Make sure it is growing in well-drained soil for best results. It is not tolerant of overly wet environments and, in fact, is tolerant of dry shade (once established) making it a perfect plant for under trees, eaves and other difficult dry areas in the garden.
A classic beauty for the woodland garden. Grown mostly for its clean variegated, soft green foliage which turns yellow in fall. Solomon's Seal is a charming plant for the shade. Standing about 18" tall and arching slightly at the top, the unbranched stems with large, alternate leaves support the dangling white flowers below. On quiet spring evenings, the flowers exude a subtle lily-like fragrance. The stems are beautiful in cut flower arrangements.
The genus Polygonatum, native to Europe, Asia, and North America.
Members of Polygonatum are excellent perennials for the landscape. The genus botanical name (Polygonatum) comes from poly (many) and gonu (knee joints) and refers to the many-jointed rhizome from which the leaves arise. The common name Solomon's Seal has several proposed derivations. The first is that the scar that remains on the rootstock after the leaf stalks die off in the fall resembles the seal impressed on wax on documents in the past. The second source is that John Gerard, the English botanist and herbalist, suggested that the powdered roots were an excellent remedy for broken bones. He also felt the plant had the capacity for "sealing wounds," which was why the perennial received the common name - Solomon's Seal.

A superb introduction, forming a clump of heart-shaped silver leaves, delicately veined with mint green. Sprays of bright blue Forget-me-not flowers appear in mid to late spring. This is a choice collector's plant, but an easy-to-grow perennial that performs well in all but the driest of shady conditions.
Excellent for the woodland garden. 'Jack Frost' handles more direct sun than most other variegated types of Brunnera, though in hot-summer regions some afternoon shade is recommended to prevent leaf scorch.
Amsonia hubrichtii grows 36 inches tall and 36 inches wide in a mounded form. This hardy perennial grows in hardiness zones 4 through 9 and is a versatile North American native.
Amsonia offers a variety of features throughout the seasons. From late spring to early summer, two to three inch wide clusters of small, light blue, star-shaped flowers are borne above the ferny foliage. The alternate-arranged leaves are bright green in spring and summer, but turn a bright yellow-golden color in fall.
Baptisia australis, False Indigo
Blue false indigo grows three to four feet tall and three to four feet wide in an upright habit. This exceptional perennial grows across a wide range of zones and is one of the most adaptable native species.
Newly emerging shoots produce violet-blue, lupine-like flowers in erect 10 to 12 inch racemes atop flower stems extending well above the foliage mound of clover-like, bluish-green leaves. The spring flowers are present for three to four weeks.
The flowers give way to inflated seed pods which turn charcoal black when ripe and which flower arrangers consider to be ornamental. The common name, blue false indigo, refers to the use of this perennial by early Americans as a dye.
Baptisia australis is an excellent plant to anchor the back of the border. It is also valuable for cottage gardens, native plant gardens, and native area of prairies and meadows.
It is best as a specimen or planted in small groups. Blue false indigo can be used with bulbs and other spring flowering perennials to make interesting combinations.
* Light - Plants thrive in full sun. Plants grown in partial shade may require staking.
* Soil - This North American native is easily grown in well-drained soil and is drought tolerant after establishment.
* Uses - This spring flowering shrub-like perennial may be used to fill the back of the border or in the wild garden.
* Unique Qualities - The combination of flower and leaf color is dramatic in the early blooming season. Flowers are followed by inflated seed pods that are useful for dried flower arrangements.
* Hardiness - USDA zones 3-9
