Ligularia

Ligularia requires partial shade to full shade and cannot tolerate the intense midday sun of NE Florida summers; afternoon shade is essential to prevent wilting and leaf scorch. It is not well-adapted to zone 9b heat — even in deep shade it struggles with summer temperatures exceeding 90°F. If grown in NE Florida, use only the most heat-tolerant cultivars (e.g., 'Othello') in heavily shaded, moist microclimates.

Ligularia requires consistently high moisture — keep the soil evenly moist at all times. In NE Florida's sandy soils, daily watering during summer may be necessary; mulch heavily to retain moisture and cool the root zone. Note that despite high moisture needs, drainage must still be adequate — soggy, compacted soil promotes crown rot.

Plant in rich, moist, organic loamy soil with slightly acidic pH (5.5–6.5); amend sandy Florida soils heavily with compost before planting. Apply a balanced slow-release fertilizer in spring. Given Ligularia's marginal adaptability in zone 9b, optimal soil preparation is critical — this plant is best suited to gardeners willing to provide intensive summer care.
