How to Grow Peruvian lily

Peruvian lily can be grown from a stem cutting, seeds, or by division. Most gardens generally prefer to propagate them through division because of their tuberous roots. 

Growing through seeds is a very time-consuming process. Also, not many gardeners can succeed to grow Peruvian lilies from seeds. 

Propagation through stem cutting is also a good choice if you want to grow multiple new plants. 


Several studies concluded that Peruvian lily is mildly toxic to humans. Touching its flower may cause skin reactions in sensitive people, also when consumed it can cause stomach upset.

How to Propagate Peruvian Lily from Division

The division is the most used method to grow Peruvian lily. You can bring one small plant from the nursery and plant it in the garden or container. 

However, if you already have one Peruvian lily, you can grow multiple other plants through division. 

But, the plant should mature or bloom for at least one season. Also, the plants do not overgrown or get crowded in an area. Avoid division, this plant does not like transplantation.

  • After digging out the plant, wash the roots with water to remove dirt from them. Cut off any damaged roots which are black. 
  • Divide the root clump into two to three sections depending on its size. It has tuberous roots. Make sure you cut the stem with each root clump.
  • Now, plant these sections in different locations in the garden. 
  • It will be established within a month, you get to know when it starts producing new foliage.

How to Grow from Seeds

Peruvian Lily

Growing from seeds is not recommended because it takes lots of time and most gardeners are not able to propagate from seeds. 

In the woods, this plant self-seeds for years. However, manually propagating from seeds is not a feasible method. Also, many gardeners prefer to grow its cultivar rather than the actual species. 

Cultivars generally do not grow from seeds. Cultivars are developed by cross-breeding two species, these cultivars are good for better flowers and growth but their seeds are not fertile. 

The plant grown from these seeds is not similar to its parent plant or in many cases, they simply do not grow.

However, Growing from seeds is very simple. Collect its seeds from dry flowers. Sow these seeds in a pot and water the soil to keep it moist.

  • Clear all the leaves from the bottom half of the plant. 
  • Plant the cutting in a pot filled with potting mix soil.
  • Plant only one cutting in a pot, avoid crowding the signal pot.
  • Water the pot to keep the soil moist. In the beginning, plants need more water to be established but avoid overwatering.
  • Place the pot in indirect sunlight till it gets established. You know when plants start producing new leaves. Once it gets established, place it in direct sunlight.

Peruvian lilies like to shine in full sunlight. They need at least six to eight hours of direct sunlight. However, in extremely hot summer conditions, they need partial shade. 

The ideal place is where they get early morning sunlight and afternoon shade. If plants get too much heat they might suffer from leaf burn. 


This plant needs regular watering, especially in hot summer conditions. They need at least 1 inches water per week. However, do not overwater them this causes soggy soil which leads to root rot. Water the plant only when it soil looks dry.


Peruvian lilies require rich, fertile, well-drained soil to grow blooms. You can improve your soil fertility and drainage by adding organic matter or soil compost

When planting adds a thick layer of soil compost for better growth. You can also mix perlite or sand in the soil to improve its drainage. When planting in a pot make sure it has adequate drainage holes to flow excessive water. 

Planting them in less fertile soil may not yield a good bloom. You can add organic compost like leaf mold, banana peel, or eggshells to the soil.

Temperature and humidity

Ideally, Alstroemeria likes to stand in temperatures between 65 to 80 degrees Fahrenheit. When the temperature becomes more than 80 degrees Fahrenheit foliage starts to burn and produce fewer flowers. In this condition, you can plant them in partial shade where they get early morning sunlight. 

In the high humid climate, plant Peruvian lily with adequate spacing to provide good circulation. So that fungal diseases do not thrive on the foliage.


Feeding once in the early spring is enough for continuous growth throughout the growing season. You can add balanced flower fertilizer to the soil. You can also add manure or used tea bags as compost to provide nutrition to the plant.

How to Deadhead Peruvian Lily

Cut Peruvian lilies stem back to encourage more blooms. Deadhead dry leaves or flowers from the plant. They might look dead but these dry parts keep sucking energy from the plant.

Deadheading them will redirect energy to grow new flowers. If you do not seek a plant to produce seeds, cut off the flower when they begin fading.


In the warm region, zones between 8 to 10. Peruvian lilies do not need to overwinter. Zone 7 in the border zone, gardeners in this zone cover the roots with a thick layer of mulch to protect them from cold. 

In the colder zones, you can overwinter this plant by digging its tuberous roots in the fall and reporting in a small pot. Replant in the next spring season. If you grow the plant in a pot, you can simply bring the pot inside the house to overwinter.

Common pests and diseases

Aphids and thrips are some common plant pests that infest Peruvian lily. Usually, these pests do not cause serious issues but these pests can transmit serious diseases to other plants.

Botrytis (gray mold): this is a fungal disease that causes furry, gray-brown spots on the leaves and stem of the plant. 

This fungal disease is very hard to cure but you can prevent it by providing adequate spacing between the plants and also water directly in the ground rather than onto the plant. Water on the plant makes the stem and foliage wet for too long, causing fungal diseases. 

Root rot: This is a common disease caused when the roots of the plant remain wet for too long. To avoid this disease, water the plant only when its soil gets dry. Use well-drained soil so that water does not stay in the soil.
