Common names

Light requirements

This plant loves full sun and thrives when it gets plenty of bright light. It can tolerate a bit of light shade, but you’ll see the most vibrant blooms when it’s soaking up those rays. If you’re growing it indoors, a sunny spot is perfect to encourage the best flower production.

Soil preferences, including pH and drainage

Stachytarpheta urticifolia prefers well-draining soil that’s rich in organic matter. It does best in slightly acidic to neutral soil (pH 6.0–7.0). A loamy or sandy mix with some added compost will keep it happy and healthy. Ensure the soil drains well to prevent any water from pooling around the roots.

Water needs

This plant is fairly drought-tolerant once established, but it still appreciates regular watering during dry spells. Water when the top inch of soil feels dry, but avoid letting it sit in standing water. Blue Porterweed doesn’t like soggy roots, so ensure good drainage.
