Water germander: complete guide

Overview

Water germander (Teucrium scordium) is an interesting, water-tolerant plant from the Lamiaceae family that is native to marshes and wet areas throughout Europe and Asia. This plant is also known as "water germander" and is valuable for wetland ecology.

Appearance and bloom

Water germander grows as a low herb, usually 20-40 cm high. The plant forms red-purple to lilac colored flowers that appear in June-September in semi-long flower spikes. The leaves have a characteristic garlic odor when touched. The plant forms underground runner stems that aid vegetative spread.

Ideal location

Water germander grows optimally along water edges, in marshes and in wet spots. The plant thrives in full sun to partial shade and tolerates damage poorly. Ensure regular water supply. Perfect for water-edge plants in gardens.

Soil type

The plant grows well in wet, nutrient-rich soils. Water germander prefers clay and silt-rich soil with high moisture content. A pH of 5.5-6.5 is optimal. Permanent water surplus or regularly flooded soils are preferred.

Watering

Watering is critical for this plant. Permanent wet soil conditions are essential. In gardens water regularly and abundantly. The plant tolerates wet feet and even stagnant water with preference.

Pruning

Pruning is not essential. In autumn wilted parts can be removed. The plant spreads via underground runners and can be shortened if needed. Minimal maintenance pruning suffices.

Maintenance calendar

In growing season regular watering. After flowering faded material can be removed. The plant spreads via runners and can be suppressed by mowing. No fertilizer needed.

Winter hardiness

Water germander is hardy to -20 degrees Celsius. In very cold winters above-ground parts can be damaged, but the plant recovers from root runners. In milder climates fully green.

Companion plants

Water germander grows well with other wet-plant specialists such as water plants, reed sedges and marsh marigold. Also together with yellow iris, marsh marigold and sedges. Ideal for water gardens.

Conclusion

Water germander is a valuable plant for those who want to use wet spots. The purple flowers brighten dark water zones. Perfect for wetlands and water-edge plants. Discover more: gardenworld.app/en
