Erysimum × allionii 'Yellow' – Golden-yellow Siberian wallflower for early garden color

Erysimum × allionii 'Yellow', commonly known as the Siberian wallflower, is a striking and colorful plant perfect for spring plantings. With its bright golden-yellow flowers, this plant instantly brings color to the garden and adds a cheerful touch to borders, rock gardens, and patios. 'Yellow' is known for its long flowering period, early blooming, and attractiveness to bees and butterflies, making it both aesthetically and ecologically valuable.

Golden yellow flowers for early color and atmosphere

The biggest asset of Erysimum × allionii 'Yellow' is its golden-yellow flowers that appear early in the season. These flowers form clusters and bloom for a long time, creating a warm, sunny atmosphere for weeks.
The fresh yellow contrasts beautifully with the vibrant green leaves and creates a striking pop of color when combined with other spring bloomers such as tulips, daffodils, and primulas.

This early and rich flowering makes the plant ideal for:

• Spring borders

• Rock gardens and stonework

• Balcony and terrace containers

• Landscape plantings

The flowers are also suitable as small cut flowers for bouquets and decorative arrangements.

Short-lived perennial or biennial plant

Erysimum × allionii 'Yellow' is a short-lived perennial that is often grown as a biennial or even an annual in colder regions. The plant is likely a hybrid between Erysimum asperum and Erysimum bicolor, which explains the combination of early flowering, vibrant color, and vigorous growth.

In milder climates the plant can sometimes return for several years, but it is usually used as a seasonal plant for early colour in the border.

Growing conditions and location

The Siberian wallflower prefers full sun but also tolerates light shade. It grows well in a variety of soil types, as long as the soil is well-drained. This makes the plant suitable for both dry borders and richer garden soil.

Maintenance is minimal. Regularly removing faded flowers encourages new blooms and keeps the plant neat. Erysimum × allionii 'Yellow' is also tolerant of cold spring nights, ensuring it blooms reliably early.

Ecologically valuable: attracts pollinators

The golden-yellow flowers of 'Yellow' are an excellent source of nectar and attract a wide range of pollinators, including:
