Perennial geraniums or cranebills are so named because of the beak-like fruits that appear after flowering. Hardy geraniums or perennial geraniums are bushy and shrub-like mounds or trailing, ground-hugging weavers. They are excellent perennial plants for mass plantings. Flower colors range from suble to vibrant. Do not confuse them with the popular annual geraniums which are a member of another genus- Pelargonium. |

Geraniums prefer full sun or part shade in cool or mild summer climates. In hottest regions, provide afternoon sun protection during the warmest months. |
| Soil Composition:
Hardy geraniums perfer moist, well-draining soil |
| Gardening Zones:
USDA zone 4, zone 5, zone 6, zone 7, zone 8, zone 9. Zones vary by variety. |
| Blooming Season:
Varies from May through September with most perennial geraniums blooming June through August. See individual listings. |
| Care and Maintenance:
After you work in organic matter, prepare a hole that is twice the diameter of the plant ball. Loosen any roots that are encircling the root ball, replant at same depth as originally planted. Back fill with the enriched soil. Water well to settle soil. Fertilize hardy geraniums with a time-release fertilizer in spring. Apply a thin top dress of bark mulch to improve water retention but do not cover stems. Divide in spring every four to five years or when bloom production noticably declines. You can also transplant rooted portions from the edge of the geranium clump in spring. |
