ON THIS PLANT

Lilium washingtonianum is a North American plant species in the lily family. It is also known as the Washington lily, Shasta lily, or Mt. Hood lily. It is named after Martha Washington and not the state of Washington; in fact, as the northern range of the plant is near Mount Hood in Oregon, it does not naturally occur in the state of Washington. Lilium washingtonianum is native to the Cascade Range and Sierra Nevada of western North America. Its range is limited to the states of California and Oregon.

CARE GUIDE

How to keep Lilium Washingtonianum.

Light

Washington lily is native to habitats like forest understories and rocky areas, where it grows in natural shade. It prefers partial sun but can tolerate full sun or full shade, showing its versatile and hardy nature.

Water

Originating from mountainous regions, the Washington lily thrives in well-drained soils with moderate moisture. While it shows some drought tolerance, it requires weekly watering to remain healthy, as it needs consistent hydration. As an herbaceous perennial, the Washington lily benefits from natural rainfall, which supports its growth and development throughout its life cycle.

Fertilizer

The primary time to fertilize Washington lily is in early spring when the flowers are developing. Using the appropriate fertilizer promotes stronger blooms and helps the Washington lily produce attractive flowers. Fertilizing in early spring ensures excellent flowering during the season and supplies energy for dormant growth phases.

Pruning

The Washington lily, known for its tall and elegant blooms, benefits from pruning in early spring. To encourage growth and flowering, trim off any dead stems and spent flowers. However, avoid cutting back the foliage until it naturally dies back. This helps transfer nutrients to the bulb, ensuring robust blooms for the next season.

What are the sunlight requirements for a Washington lily?

The Washington lily, known botanically as Lilium washingtonianum, thrives in conditions where it can receive the right amount of sunlight. It requires 'Full sun,' meaning it should be placed in a spot that gets above 6 hours of sunlight daily. If full sun conditions are not met, it can also grow under 'Partial sun,' which refers to about 3-6 hours of sunlight. When choosing a location for your Washington lily, it's essential to observe how sunlight moves through your garden throughout the day. Selecting the ideal location helps ensure that your plants receive a perfect balance of light and shade, contributing significantly to their health and growth.
