Mountain-laurel
Eastern North American native heath-family shrub with patterned cup-shaped flowers; distinct from bay laurel and western mountain-laurel names.
Kalmia latifolia · Evergreen flowering shrub
Profile
- Site
- Partial shade with cool roots
- Soil
- Acidic, humus-rich and freely draining; heavy wet clay is unsuitable
- Pruning
- Light pruning or deadheading after flowering; next blooms form on old growth
- Safety
- Highly toxic if eaten; dwarf cultivars differ from the usual 6–10 ft shrub
Water & soil targets
- Moisture (VWC)
- Site-calibrated; depends on soil texture
- Salinity tolerance
- Avoid saline irrigation and road-salt exposure.
- Drought tolerance
- Moderate once established on suitable soil; avoid prolonged root drying.
Optimal root measurement depth
4–8 in
Fine, shallow roots that dry out quickly. Typical guidance; confirm with a soil probe on site.
Keep evenly moist but never waterlogged; light mulch keeps roots cool, and raised planting may help where drainage is poor.
Problems to watch
- Phytophthora root rot
- Leaf spots
- Lace bugs
Stress signs
- Wilt in moist soil
- Brown leaf lesions
- Stippled pale leaves with dark undersides
Where you'll find it
- Woodland garden
- Native evergreen flowering border
