Growing, Harvesting and Storage

Lysimachia christinae grows in well-drained, moist soil in partial to full sun, thriving in temperate climates with cool, humid conditions.

It prefers loamy or sandy soils enriched with organic matter and requires regular watering to maintain consistent moisture without waterlogging. To ensure healthy growth, it should be planted in early spring after the last frost, with spacing to allow for air circulation and prevent fungal diseases. Harvesting is best done in late summer to early autumn when the leaves and stems are most potent, using sharp scissors or pruning shears to cut the top 10-15 cm of the plant for maximum yield.

After harvesting, the plant material should be shade-dried in a well-ventilated area to retain its medicinal properties, then stored in airtight containers in a cool, dark place to preserve potency and extend shelf life.
