Lilium regale: complete guide

Overview

Lilium regale, known as the regal lily or royal lily, is one of the most elegant and famous lilies in the world. This majestic lily from West Sichuan in China is known for its large, pure white trumpet flowers with purple streaks on the outside. The fragrance is overwhelmingly sweet and pleasant.

The regal lily is reliable, hardy, and grows well in temperate climates. It is a classic choice for front yards and gardens worldwide. With well-draining soil and a sunny location, this lily will return for decades.

Appearance & Bloom

Lilium regale grows to 90-180 centimeters tall, depending on growing conditions. The flowers are very large, up to 15 centimeters long, pure white on the inside with yellow stamens. The outside is rose to purple-red, especially on the backs. Yellow throats also occur.

Each bulb typically bears 5-8 flowers, though strong specimens can have up to 20. Flowering occurs from July to August. The fragrance is unmatched - sweet, intense, and very pleasant.

After flowering, interesting seed pods form that are also decorative. The leaves are narrow and green.

Ideal Location

The regal lily grows best in full sun to lightly shaded spots. At least 5-6 hours of direct sunlight daily is ideal. The plant can also thrive in somewhat less sunny locations, though blooming may be lighter.

Plant in a location where fragrance can be maximally enjoyed. The plant is also great to grow in containers.

Soil

Well-draining soil is critical. Heavy clay soils should be improved with sand and organic matter. Plant in raised beds or where water drains quickly. Lightly acidic to neutral pH is ideal. Very fertile soils can promote excessive growth.

Watering

Consistent moisture during growth is important. Water when the top layer feels dry. Prevention of waterlogging is critical. After blooming, gradually reduce watering as the stem dies back.

In containers, water thoroughly, ensuring good drainage.

Pruning

Remove faded flowers to maintain neat appearance. Keep the stem intact until it dies back - nutrients return to the bulb. Only then can you prune.

Maintenance Calendar

March-April: Growth starts. Water regularly. May-June: Continued growth. July-August: Blooming. Enjoy the flowers and fragrance! September-October: Stem dying back. Gradually reduce watering. November-February: Dormancy. Minimal maintenance.

Annually after blooming: Add compost.

Winter Hardiness

Lilium regale is hardy to -20 degrees Celsius, making it extremely winter-hardy in most European regions. In very wet, heavy soils, improved drainage is essential.

Companion Plants

The regal lily combines beautifully with roses, lavender, catmint, and other summer bloomers. Silver-leaved plants help highlight the lilies. Dark purple clematis or salvias form lovely contrasts.

Ensure companion plants do not grow taller than the lilies.

Closing

Lilium regale is a true classic that generations of gardeners have cherished. The fragrance, elegance, and reliability make it a top choice. Bulbs are widely available at garden centers in spring.
