Peruvian Lily Alstroemeria Indian Summer = 'Tesronto' (PBR) (Summer Paradise Series)

Water

Peruvian lily, commonly known as Alstroemeria, requires regular watering to keep the soil consistently moist but not waterlogged. During active growth in spring and summer, water approximately once a week with about 1 gallon per plant, adjusting for particularly hot or dry weather. Reduce watering in the fall and further in the winter when the plant is dormant. Always check the soil moisture level before watering to ensure it has partly dried since the last watering. Overwatering can lead to root rot, so ensuring good drainage is key.

Light

Peruvian lilies thrive in bright, indirect sunlight. The ideal spot for them is one where they are protected from the harsh afternoon sun, which can scorch their leaves, yet still receive plenty of morning and early afternoon light. An area with dappled sunlight throughout the day is also suitable, especially in a garden setting.

Temperature

Peruvian lilies prefer moderate temperatures and can typically survive in a range that flutters between 40°F at night to around 80°F during the day. They enjoy a cooler climate and do not fare well in extreme heat. The ideal growing temperature for these plants is between 65°F and 75°F during the growing season.

Pruning

Peruvian lilies require pruning to maintain health and vigor. Deadhead spent flowers to encourage continued blooming and remove any dead or damaged foliage as needed. Prune back the stems in late fall or early winter after the first frost. This helps tidy the plant and encourages new growth in the spring. Be cautious not to over-prune, as this can reduce the number of blooms.

Cleaning

As needed

Soil

The Peruvian Lily 'Indian Summer' prefers well-draining soil amended with organic matter, such as compost or well-rotted manure. A soil pH between 6.5 and 7.0 is ideal, ensuring adequate nutrient availability and a supportive environment for root growth.

Repotting

Peruvian Lilies should be repotted every 2 to 3 years to refresh the soil and accommodate root growth. For optimal health, repot in the spring before the new growth starts.

Humidity & Misting

Peruvian Lily 'Indian Summer' thrives in moderate humidity, around 40-60%. Too much humidity can promote fungal diseases, while too little can cause stress.

Suitable locations

• Indoor

  Place in bright, indirect light and ensure good air circulation.

• Outdoor

  Plant in partial sun, shelter from intense heat.

• Hardiness zone

  7-10 USDA

Life cycle

Alstroemeria, or Peruvian Lily, begins its life cycle when a seed germinates, typically in warm, moist soil conditions. The seedling develops into a young plant with a strong root system and foliage. This perennial herbaceous plant matures and forms clumps with multiple stems bearing lance-shaped leaves. During the flowering stage, which occurs in the summer for the 'Indian Summer' variety, vibrant orange, yellow, and pink blooms appear, usually with distinctive streaks or spots. After pollination, the flowers produce capsules filled with seeds that eventually disperse, completing the reproductive cycle. During the winter or in response to harsh conditions, the plant may become dormant, retreating to its tuberous roots to persevere until the next growing season.

Propogation

• Propogation time

  Spring-Summer

• Alstroemeria Indian Summer, commonly known as Peruvian Lily or Lily of the Incas, is usually propagated by division, which is the most popular method. The ideal time for propagation is either in the spring as new growth appears or in the fall after the blooming period has ended. To propagate by division, carefully dig up the clump of rhizomes making sure to keep a good amount of soil around the roots to avoid damage. Separate the rhizomes gently by hand or using a sharp knife, ensuring each division has at least one growth bud. Replant the divisions immediately, spacing them about 12 to 18 inches (approximately 30 to 46 centimeters) apart to give them enough room to grow. Water them well after planting to help establish the roots. This method is preferred as it maintains the characteristics of the parent plant and allows for a relatively quick increase in the number of plants.
