Erysimum Yellow 2ltr

Erysimum ‘Yellow’ is a wonderfully bright, cheerful perennial that brings a sunny glow to borders and pots. Producing clusters of golden-yellow flowers, it’s brilliant for lifting spring and early-summer planting and mixing with everything from pastel tulips to bold purples and deep blues. Like most wallflowers, it’s often lightly scented and a real magnet for pollinators—so it doesn’t just look good, it helps the garden buzz too.

Supplied in a 2 litre pot, this is a strong, well-established plant that will settle in quickly and start flowering happily with minimal fuss. It’s ideal for mixed borders, gravel gardens, and containers, especially where you want reliable colour that keeps going.

Planting Instructions

When to Plant:

Plant in spring or autumn, while the soil is moist and workable. Container-grown plants can be planted at most times of year, but avoid frozen or waterlogged ground.

Where to Plant:
Choose a sunny position (or light shade) with well-drained soil. Erysimum thrives in borders, cottage gardens, gravel gardens and patio containers. It prefers soil that doesn’t stay wet in winter, so good drainage is key.

How to Plant:

• Depth: Plant at the same depth as in the pot, with the crown level with the soil surface.
• Spacing: Space 30–40 cm (12–16 inches) apart to allow plants to fill out and keep good airflow.
• Soil Prep: On heavy soil, add grit or sharp sand to improve drainage. Avoid over-feeding—Erysimum prefers moderately fertile soil.

Watering:
Water well after planting. Once established, Erysimum is fairly drought tolerant, but water during prolonged dry spells, especially in its first season and when grown in pots.

Aftercare Tips:

• Deadhead spent blooms regularly to encourage a longer flowering season.
• Lightly trim back after the main flush to keep plants compact and encourage fresh growth.
• In colder or wetter areas, ensure plants have good drainage to help them overwinter successfully.

Top Tip:
Yellow Erysimum looks fantastic with blues and purples—try pairing with Salvias, Nepeta or Alliums for a classic, high-contrast display.
