Description

Source: leafsnap

Rhododendron tomentosum (syn. Ledum palustre), commonly known as marsh Labrador tea, northern Labrador tea or wild rosemary, is a flowering plant in the subsection Ledum of the large genus Rhododendron in the family Ericaceae.

🌳 Labrador tea might offer uses beyond its established applications, for instance as a natural source of botanical insecticides. Its secondary metabolites include compounds that have been observed to discourage insect feeding, indicating it could be developed into environmentally friendly pest-management solutions.

Care Guide

💧 Water Every 7 days
Suggested frequency: Every 7 days
☀️ Light Full sun

Labrador tea grows best where sunlight is plentiful and continuous throughout the day. It can tolerate areas with less light, although this may affect its healthy growth. Coming from habitats with abundant sun, insufficient light can cause stunted growth, while excessive exposure can lead to leaf burn.

Ideal: Full sun
🌡️ Temperature 5–32.2°C

Labrador tea is a versatile plant that thrives in ambient temperatures of 41 to 89.6 °F (5 to 32 ℃). It favors a cooler, temperate climate. In regions with harsh winters or extreme summers, seasonal temperature adjustments may be necessary.

Ideal temperature: 5–32.2°C

🌱 Fertilizer

Timing matters for feeding Labrador tea. Begin fertilizing in early spring and continue on a monthly schedule through early summer. Fertilizer encourages attractive blooms and supplies energy during both dormant periods and active growth.
