Family Campanulaceae

The Campanulaceae are herbs, shrubs , or rarely small trees comprising about 70 genera and 2,000 species usually with milky sap . The leaves are nearly always alternate and simple ; stipules are absent The flowers are bisexual , and actinomorphic in the subfamily Campanuloideae but zygomorphic in the Lobelioideae. The perianth and androecium are usually 5-merous, sometimes 3-10-merous. The calyx and corolla each consist of connate segments. The stamens equal the number of corolla lobes , alternate with them, and are adnate to the extreme base of the corolla or epigynous zone or more commonly arise from the annular epigynous nectary disk; the filaments are distinct and the anthers are introrse and only weakly connivent around the style in the Campanuloideae but in the lobelioideae the introrse anthers and also often the filaments are firmly connate. The gynoecium consists of a single compound pistil of usually 2 carpels and locules with numerous axile ovules in the subfamily Lobelioideae but usually consists of 3-5 carpels and locules with numerous axile ovules in the subfamily Campanuloideae. The single style commonly has a number of lobes or stigmas equal to the number of carpels. The ovary is nearly always inferior and is generally crowned with an epigynous annular nectary disk. The fruit is usually a capsule or berry. -- Gerald Carr.

Growth

Culture: Space 4-6" apart. Self-sows. Propagation : Divide the rootball, or start from seed. Allow seed heads to dry on plants before collecting. Start seeds indoors 10 to 12 weeks before the last spring frost. Place seeds on top of finely prepared soil. After sowing, moisten the potting mix and place the seed tray in a cool place or refrigerator for 2 weeks, then move to a 65-70°F. area. Seedlings emerge in 2-3 weeks. Transplant after all danger of frost is past.

Soil: Requires damp soil. Prefers rich organic , moist soil, pH 6.5 to 7.5.

Sunlight: Sun Exposure: Full sun where summers are cool, light shade for areas with hot summers. Tolerates full shade, but better blooms with partial sun. Shade helps deepen the intensity of blooms

Moisture: Water Requirements: Very high moisture needs. Keep soil mixture moist until well established . Water daily during hot, dry summer. Suitable for water gardens.

Temperature: Cold Hardiness: 3a, 3b, 4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b (map)
