Solomon’s Seal Plant Care

Size & Growth

The Angular Solomon’s Seal is a shade-loving plant growing 18” to 24” inches high on unbranched and arching stems. 

It spreads slowly by rhizomes to create colonies in ideal growing conditions. 

These plants are slow to grow in a landscape but are usually long-lived, and easier to maintain.

The alternate green leaves on the stems support the dangling flowers. 

The stems make a beautiful addition in arrangements of cut flowers.

Flowering and Fragrance

This plant produces bell-shaped, creamy-white flowers in the late spring season, which dangle underneath the variegated leaves. 

In early spring evenings, the flowers radiate a subtle perfume-like fragrance.

The smell of these fragrant flowers resembles the scent of hyacinths and lilies. 

The bloom time is usually between April and May.

Light & Temperature

Solomon’s Seal is a woodland plant and prefers to grow in full shade. 

This plant may tolerate the sun if it is growing in moist soil and cool climate. 

It requires at least part shade to perform well. 

However, once it establishes, it is a rather drought tolerant plant.

These plants are hardy to USDA Hardiness Zones 3 through 8.

Watering and Feeding

The Variegated Solomon’s Seal loves growing in consistently moist soil. 

It shouldn’t be overly wet as it might damage the plant. 

Let the soil slightly dry before you water the plant thoroughly.

This plant is a light to moderate feeder. 

Deliver the necessary nutrients with a controlled-release or water-soluble fertilizers. 

If you are using water-soluble fertilizers, be sure to apply 75 to 100 ppm nitrogen content.

Soil & Transplanting

The P. Odoratum prefers a humusy, well-draining moist soil mixture. 

Provide it with organically rich soil with pH levels between acidic to neutral.

Grooming and Maintenance

It is relatively easy to take care of this plant. 

Make sure the soil is consistently moist, but avoid overwatering this plant. 

When planting, be sure to leave sufficient space between the plants to give them room to grow properly.

This plant quickly multiplies in the garden by rhizomes. 

Divide the plant when required and transplant them in shady areas if they start outgrowing the space. 

There isn’t a need to deadhead this plant as the small flowers drop off the stem naturally.

The foliage stays beautiful throughout the year, which makes this plant maintenance-free. 

Even the stems detach from rhizomes after the frost. 

The foliage changes color during the fall season, turning into a breathtaking golden yellow color.

However, after sowing the seeds, the plant will need special treatments like stratification.

Minor treatments will help in getting rid of these issues.
