The soil should be kept moist but not waterlogged, as excessive water can lead to root rot. To improve soil quality, adding organic matter such as compost or peat moss is recommended.
Overall, providing the right growing conditions for Cardamine purpurea Cham. & Schlecht. var. albiflora Hultén can lead to a beautiful and healthy plant that can enhance any garden or natural area.
Cultivation
Cardamine purpurea Cham. & Schlecht. var. albiflora Hultén, also known as the Whiteflower Bittercress, is a perennial herb that prefers a slightly acidic soil with good drainage. It can grow up to 20 cm in height and spreads through its rhizomes. This plant thrives in partial to full shade and requires a moderate amount of water to thrive.
Watering Needs
The Whiteflower Bittercress requires regular watering to keep the soil moist, but not waterlogged. Overwatering can lead to root rot and damage the plant. It is recommended to water the plant deeply once a week, and adjust the frequency based on the soil moisture level. Check the soil moisture by sticking your finger in the soil up to the first joint; if it feels dry, it is time to water.
Fertilization

However, a slow-release fertilizer can be added during the growing season to promote growth and blooming. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Avoid using too much fertilizer as it can lead to excessive leaf growth and soften the plant.
Pruning
The Whiteflower Bittercress requires minimal pruning. To maintain the plant's shape and prevent it from becoming too leggy, you can pinch the stem tips during the growing season. Deadheading is also necessary to promote blooming throughout the season. Remove spent flowers by cutting the stem just below the flower. This will encourage the plant to produce more flowers.
