Peruvian lily 'Sweet Laura' Alstroemeria 'Sweet Laura' (PBR)

Water

For the Peruvian Lily, which is the common name for Alstroemeria 'Sweet Laura', regular watering is essential to keep the soil consistently moist but not waterlogged. During the growing season, water thoroughly once a week with approximately one gallon of water per plant. In hotter temperatures or if the plant is in a container that dries out faster, check the soil moisture more frequently and water as needed to maintain moisture. Reduce watering in the winter months when the plant is not actively growing. Avoid overhead watering to prevent disease; instead, water at the base of the plant.

Light

Peruvian Lilies thrive best in full sun to partial shade. A location that receives morning sunlight and partial afternoon shade is ideal to protect the flowers from intense, midday heat which can be detrimental. East or west-facing spots that provide at least 6 hours of sunlight are excellent choices for these plants.

Temperature

Peruvian Lilies, such as Alstroemeria 'Sweet Laura', prefer temperatures between 65 to 80 degrees Fahrenheit during the day and should not be exposed to temperatures below 29 degrees Fahrenheit as they can be damaged by frost. Ideal nighttime temperatures range from 40 to 50 degrees Fahrenheit. While they can survive brief periods of higher or lower temperatures, consistently staying within this range is optimal for their growth.

Pruning

Peruvian Lilies should be pruned to encourage vigorous growth and more blooms. Deadhead spent flowers regularly to promote continuous flowering. After the blooming season, cut back the stems to ground level to encourage the plant to store energy for the next season. The best time for this heavier pruning is in late autumn or early winter after the first frost has passed.

Cleaning

As needed

Soil

Peruvian Lily 'Sweet Laura' prefers well-draining, fertile soil with a pH of around 6.5. A good mix would be part loamy soil, part peat, and part sharp sand or perlite to ensure proper drainage. Regularly organic matter can be added to keep the soil fertile.

Repotting

Peruvian Lilies should be repotted every two to three years or when the clumps become overcrowded. Transplant 'Sweet Laura' during spring or early summer for best results.

Humidity & Misting

Peruvian Lily 'Sweet Laura' thrives in moderate humidity levels. Aim for around 40-60% relative humidity for optimal growth. Avoid excessively dry or damp air.

Suitable locations

• Indoor

  Place 'Sweet Laura' in bright, indirect light and ensure the pot drains.

• Outdoor

  Plant in partial shade, shelter from strong winds, and well-drained soil.

• Hardiness zone

  5-9 USDA

Life cycle

Alstroemeria 'Sweet Laura', commonly known as Peruvian Lily or Lily of the Incas, begins its life cycle when seeds germinate, typically in spring, requiring warmth and moisture. The seedlings develop into young plants with characteristic lance-shaped leaves, and as they mature, rhizomatous roots form which help the plant establish itself firmly in the soil. During the growing season, usually from late spring to early summer, the Peruvian Lily produces stems that bear clusters of striking, funnel-shaped flowers in shades of yellow and orange, marked with characteristic streaks and spots. After blooming, which can last several weeks, the plant enters a period of dormancy, especially in regions with colder winters, retreating to its rhizomes to conserve energy. In the following growing season, it emerges again, often producing new shoots from the rhizomes, and perpetuating its growth cycle. With adequate care, Alstroemeria 'Sweet Laura' can continue this cycle for several years, spreading slowly through its rhizomes to form larger clumps.

Propogation

  Spring-Early Summer

• The most popular method of propagation for Alstroemeria 'Sweet Laura', commonly known as the Peruvian Lily or Lily of the Incas, is by division of its tuberous rhizomes. This is typically done in the spring or early summer when the plant has finished blooming and is entering its dormant phase. Gardeners should carefully dig up the clumps, trying not to damage the roots, and then gently separate the rhizomes by hand, ensuring that each division has at least one growth point or eye. These divisions can then be immediately replanted in well-draining soil at a depth of about 6 to 8 inches (15 to 20 centimeters), spaced approximately 12 to 18 inches (30 to 45 centimeters) apart to allow for adequate growth. Adequate watering and light fertilization will help establish the new plants. This approach encourages the healthiest growth and maintains the vigor of the cultivar.
