Princess Lilium, also known as Peruvian Lilies or Alstroemeria, are compact, vibrant plants. They are a popular choice for gardeners, adding color to smaller spaces like patios and balconies, and are well-suited for container gardening.
Understanding Princess Lilium
Princess Lilium refers to cultivars of Alstroemeria, widely known as Peruvian Lilies or Inca Lilies. These plants are distinct from true lilies (Lilium species) due to their compact stature, growing 10 to 24 inches tall. This makes them ideal for container cultivation or foreground plantings.
Princess Lilies feature sturdy stems bearing clusters of vibrant, funnel-shaped flowers, often with streaks or spots. Their bloom period is long, extending from spring through summer, and often into fall. Flower colors include pink, orange, yellow, red, white, and purple. These varieties are bred for continuous flowering and a robust growth habit.
Planting Princess Lilium
Princess Lilium thrives in locations with full morning sun and partial afternoon shade, which protects them from intense heat and promotes vigorous growth. Well-draining soil is crucial; their tuberous roots are susceptible to rot.
For container planting, use a high-quality potting mix with adequate drainage holes. In garden beds, amend heavy clay soils with organic matter like compost to improve drainage and aeration.
Plant Princess Lilium tubers or rhizomes in spring or fall, about 6 inches deep. Space plants 8 to 12 inches apart for air circulation and root development. After planting, water thoroughly to settle the soil.
Caring for Princess Lilium
Consistent moisture is important for Princess Lilium, especially during active growth and flowering. Water deeply when the top inch of soil feels dry, ensuring moisture reaches the root zone without creating soggy conditions. Avoid overhead watering to prevent fungal diseases.
Princess Lilium performs best with consistent bright light, ideally morning sun followed by afternoon shade in warmer climates. Adequate air circulation also contributes to health and deters fungal issues.
Fertilization supports robust growth and abundant flowers. Apply a balanced, slow-release granular fertilizer (e.g., 10-10-10) or a liquid feed for flowering plants every few weeks during the growing season. Follow product instructions to avoid over-fertilization.
Deadheading spent flowers redirects the plant’s energy into continuous blooming and tuber development. Pluck the entire flower stem from the base to stimulate new growth. Allow foliage to remain until it yellows naturally, as leaves photosynthesize and store energy for future blooms.
Common Challenges and Solutions
Yellowing Princess Lilium foliage often indicates watering or nutrient issues. Overwatering can lead to root rot, while insufficient water stresses the plant. Adjust watering frequency for consistent moisture. If nutrient deficiency is suspected, apply a balanced fertilizer.
Lack of blooms frequently stems from inadequate light exposure. Princess Lilium needs sufficient sunlight for optimal flowering; relocate to a brighter spot with morning sun. Improper fertilization, such as excessive nitrogen, can also inhibit blooming.
Common garden pests like aphids may congregate on new growth and flower buds. A strong water spray can dislodge aphids, or insecticidal soap can manage larger infestations. Slugs and snails can chew holes in leaves and flowers. Hand-picking or using baits protects foliage.
