Description

Family Rubiaceae

The Rubiaceae are trees , shrubs , or infrequently herbs comprising about 450 genera and 6,500 species, including some lianous forms. The leaves are simple and usually entire, and are opposite or sometimes whorled ; stipules are present and interpetiolar . The flowers are nearly always bisexual and actinomorphic , often heterostylous, and usually are in cymose inflorescences. The calyx is mostly somewhat reduced and 4-5-lobed or sometimes the lobes are obsolete or rarely one of them greatly expanded and brightly colored . The sympetalous corolla is mostly 4-5-lobed, occasionally with 3 or up to 10 lobes. The androecium consists of as many stamens as corolla lobes and is adnate to the corolla tube or epigynous zone, alternate with the lobes. The gynoecium consists of a single compound pistil of 2 or seldom more carpels, a single style, and a nearly always inferior ovary with the number of locules equaling the number of carpels, each with 1-many axile ovules. An epigynous nectary disk is usually present. The fruit is variable, sometimes forming multiples . -- Gerald Carr.

Physical Description

Habit: Subshrub , Forb/herb

Flowers: Dense clusters of tiny, fragrant flowers bloom in April, May, June, July.

Foliage: Summer foliage: Bright green emergent foliage matures as dark green. Hay-scented leaves are hairy underneath, in whorls of 8-12 on stems. Leaflet is lanceolate or narrow elliptical .

Size/Age/Growth

Growth Rate: Moderate growth of perimeter spread . • Size: 6-12" tall.

Landscaping

Landscape Uses: Excellent for shady rock garden. Beautiful groundcover for partial shade and moist, loamy soil. Mass planting . Embankments . Borders . Naturalized areas. • Care: Deer resistant. Drought tolerant (will seem to die back, but will recover when moisture returns). Low maintenance . Can be grown under black walnut trees . Deadhead to prevent self-sowing, if you wish to prevent volunteers. Follow a regular watering schedule during the first growing season to establish a deep, extensive root system . Control weeds until the plants have filled in. Feed with a general purpose fertilizer .

Reproduction

Duration: Perennial

Growth

Culture: Great groundcover for a shady spot. Self-sows freely, spreads quickly. Spreads slowly at its perimeter by the procumbent rooting stems. Propagate by separating rooted stems, by crown division, or digging the submerged perimeter stolons.

Soil: Needs good organic , moist, well-drained soil. Tolerates average, well-drained, dry, thin soils.

Sunlight: Sun Exposure: Partial to full shade. Prefers partial shade.

Moisture: Water Requirements: Water regularly, before top 3 in. of soil becomes dry, particularly in hot dry summers.

Temperature: Cold Hardiness: 4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b. (map)
