Peruvian Lily Alstroemeria Princess Juliana = 'Staterpa' (Princess Series)

Water

To properly water the Peruvian Lily, ensure the soil is kept consistently moist but not waterlogged. During the growing season, water the plant thoroughly once a week using about 0.5 to 1 gallon of water each time, depending on the size of the plant and the environmental conditions. In hotter, drier periods, you may need to water twice a week. Ensure that the water penetrates deeply into the soil to encourage deep root growth. Reduce watering in the winter months when the plant is not actively growing, and allow the soil to dry out slightly between waterings.

Light

Peruvian Lilies prefer bright, indirect sunlight. The best spot for this plant is in an area where it can receive plenty of light throughout the day but is shielded from the harsh midday sun. A location near an east or west-facing window is ideal, where it can enjoy the softer morning or late afternoon sun without the risk of scorching its leaves.

Temperature

Peruvian Lilies thrive in temperatures ranging from 65 to 80 degrees Fahrenheit, which are typically considered ideal conditions. They can withstand minor dips down to around 50 degrees Fahrenheit but should be protected from frost. During extreme heat or cold spells, take steps to moderate the environment, as temperatures outside of 50 to 80 degrees Fahrenheit can stress the plant.

Pruning

Prune Peruvian Lilies to remove faded or dead flowers and to keep the plant looking tidy. This also encourages more blooms. Cut back the flower stalks to the base of the plant after flowering. Pruning is best done in the late fall or early spring before new growth begins. Additionally, remove any damaged or diseased leaves as soon as they are noticed to maintain plant health.

Cleaning

As needed

Soil

Peruvian Lily requires well-draining soil enriched with organic matter, such as compost or peat moss. The best soil mix might contain two parts loam, one part sand or perlite, and one part organic material. The soil pH should be slightly acidic to neutral, ranging from 6.5 to 7.0 for optimal growth.

Repotting

Peruvian Lily should be repotted every two to three years to refresh the soil and accommodate root growth. Carefully lift the plant and increase the pot size if roots have become crowded.

Humidity & Misting

Peruvian Lily thrives best in moderate humidity. Aim for relative humidity levels between 40% and 60% for the healthiest growth, avoiding conditions that are too dry or excessively moist.

Suitable locations

• Indoor

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

• Outdoor

  Plant in partial shade and shelter from strong winds.

• Hardiness zone

  7-10 USDA

Life cycle

Alstroemeria Princess Juliana, commonly known as Peruvian Lily or Lily of the Incas, begins its life cycle as a rhizome, a type of underground stem that stores nutrients. Upon planting in well-draining soil with adequate sunlight, the rhizome will sprout and grow into a lush green plant, with leafy stems supporting the growth. As the plant matures, it produces distinctive funnel-shaped flowers, often in vibrant shades of orange, marked with streaks and spots. The blooming phase can occur from late spring to early fall, during which time the plant can be propagated either by division of rhizomes or through seed germination, though the latter is less common with hybrids like the Princess Series. After the flowering period, the plant enters a dormant phase, particularly in colder climates, whereby the foliage may die back, and the rhizome remains dormant until favorable growth conditions return. As a perennial, the Peruvian Lily will reemerge from dormancy in spring to repeat the growth cycle, living for several years with proper care and conditions.

Propogation

  Spring-Early Summer

• Alstroemeria, commonly known as Peruvian Lily or Lily of the Incas, is most commonly propagated through division, which is typically done in the spring. To propagate through division, carefully lift the clump of tubers from the ground after the flowering has finished and the plant has begun to die back. Gently tease apart the individual tubers with your hands or use a sharp knife if necessary, ensuring that each section has at least one eye, which is a growth point where new shoots will emerge. Replant the divisions immediately at the same depth they were growing previously, spacing them about 12 to 24 inches (30 to 60 centimeters) apart to allow for ample growing space. Water the divisions thoroughly after planting to help establish them. This method is effective for increasing your stock of Alstroemeria Princess Juliana and maintaining the health and vigor of your plants by rejuvenating crowded clumps.
