| Plant Type | Perennial plant | |
| Estimated Plant Lifespan | 12 years lifespan | |
| Sun Requirements | 2-4 hours direct sunlight (Partial Shade) | |
| Pollination | Method: animal Notes: Pollinated by insects, primarily bees, which are attracted to its creamy white to pink flower plumes. No manual pollination is typically required for successful growth or seed production. | |
| Watering Requirements | Method: top water Frequency: keep constantly moist Notes: Rodgersia requires consistently moist soil and does not tolerate drying out, especially during hot periods. It thrives in locations near water bodies or in boggy garden areas where moisture is abundant. Ensure good drainage to prevent waterlogging, but aim for a continually damp root zone. | |
| Humidity Requirements | Level: moderate to high Maintenance: Planting in shaded, sheltered locations with good air circulation helps maintain localized humidity. Mulching around the base of the plant can also help retain soil moisture, contributing to humidity levels near the foliage. | |
| Care Instructions | Protect Rodgersia from strong winds, as their large leaves can be easily damaged or tattered. Remove spent flower stalks after blooming to maintain a tidy appearance, though some gardeners leave them for winter interest. In colder zones (USDA Zone 5), applying a winter mulch can provide additional root protection. Divide clumps every few years in spring or autumn to maintain vigor and size. |
Sedum species require full sun and very well-drained, even dry soil conditions. Planting them with Rodgersia, which thrives in moist shade, would lead to poor performance for the Sedum and an unsuitable environment for both plants.
Lavender needs full sun, excellent drainage, and even poor soil to thrive. It would quickly suffer from root rot and decline in the consistently moist, humus-rich soil preferred by Rodgersia, making them incompatible companions.
Yucca requires full sun and extremely well-drained, dry conditions. Its drought-tolerant nature is completely at odds with Rodgersia's need for consistent moisture, making them unsuitable for co-planting.
Slugs are a common pest for Rodgersia, especially in moist conditions. They feed on the large, succulent leaves, creating irregular holes and ragged edges, particularly on new growth. Damage is often visible at night or on damp mornings, sometimes accompanied by silvery slime trails.
Similar to slugs, snails also cause significant damage to Rodgersia leaves by chewing holes. They are typically more active in damp, cool conditions. Evidence includes holes in leaves and the presence of their shells.
While less common than slugs/snails, vine weevil larvae can feed on the roots of Rodgersia, leading to wilting, stunted growth, and in severe cases, the collapse of the plant. Adult weevils chew notches in leaf margins, but larval root damage is more detrimental.
Steps:
- Choose a mature, healthy clump of Rodgersia, ideally in early spring as new growth begins to emerge, or in autumn after flowering.
- Carefully dig up the entire plant clump, trying to retain as much of the root ball as possible.
- Gently shake off excess soil to expose the rhizomes (underground stems) and roots.
- Using a sharp, clean knife or spade, divide the rhizome into sections. Ensure each section has a healthy portion of roots and at least one 'eye' or bud (where new growth will emerge).
- Replant the divisions immediately into prepared soil that is rich in organic matter and moist. Plant at the same depth as the original plant.
- Water thoroughly after planting and keep the soil consistently moist until the new divisions are established.
Iron Phosphate Slug Pellets
An effective and pet-safe way to control slugs and snails, which are common pests for Rodgersia, without harming wildlife.
Compost or Leaf Mold
Enhances soil fertility, improves drainage while retaining moisture, and provides essential organic matter that Rodgersia thrives in. It supports robust growth and health.
Shredded Bark Mulch
Helps retain soil moisture, suppresses weeds, and regulates soil temperature, all of which are beneficial for Rodgersia's growth. It also breaks down to add organic matter.
Diatomaceous Earth
A natural, non-toxic powder that can be sprinkled around the base of plants to deter slugs and snails by creating a physical barrier that dehydrates them.
