Whiteweed, commonly referred to as 'Flossflower', requires routine care for optimal growth. Basic care involves providing full sun or partial shade, weekly watering, and humus-rich, well-drained soil. Whiteweed prefers temperatures around 60-75°F (15-24°C). Common challenges arise from pests such as aphids and leaf miners, and diseases such as powdery mildew. Extreme temperatures and insufficient draining may lead to plant stress. Seasonally, the whiteweed benefits from regular deadheading in summer for continuous bloom, and reducing water in winter to protect roots from frost damage.
