Erysimum perofskianum

Growing in Pots, Balconies & Indoors

Erysimum perofskianum is a short-lived, sun-loving wallflower. The grower confirms it is not a houseplant but grows well in containers, so grow it on a bright sill or a sunny patio for its cheerful early flowers.

Quick Details

• Container Size: 5-10 L – a compact 10-40 cm plant
• Indoor Suitability: Not a houseplant; a compact plant can flower on a bright, sunny windowsill
• Best Spot: Full sun to light shade – the brightest spot you have
• Soil & Drainage: Free-draining potting mix; it dislikes heavy, wet compost
• Watering in Pots: Keep evenly moist while growing and flowering; ease off and never leave it waterlogged

Indoors & On the Windowsill

• Not a houseplant: The grower marks it as unsuitable indoors – it needs strong, direct light to flower and stay compact.
• Windowsill: A sunny sill with direct light is the only indoor option; short-lived by nature, it is easy to raise fresh from seed each year.
• Overwintering: A pot lets you shelter young plants from the harshest frost in a bright, cold-but-protected spot before they flower.

On a Balcony or Patio

• Light & wind: Give it the sunniest position; it copes with lean soil and is a fine early nectar plant. Pots against warm walls dry fast – check moisture.
• Practicalities: Neat and low, it suits the front of a sunny pot display; let runoff drain away.

Choosing the Pot, Soil & Long-Term Care

• Pot & drainage: A pot with strong drainage holes; skip a standing-water saucer, which invites root rot. Terracotta breathes and dries faster (good for plants that hate wet feet); glazed or plastic pots hold moisture longer.
• Potting mix: Well-aerated potting mix – a peat-free or peat/coir blend opened up with perlite or vermiculite.
• Feeding: Feed sparingly – a weak balanced feed a few times in the growing season; these plants dislike rich conditions and lush, soft growth.
• Repotting: Refresh the top of the mix each year and pot on or divide every couple of years, lightly trimming roots and old growth to keep it vigorous.

Bloom & Flower Guide

Quick Details

• Bloom Season: Spring into summer, often in a strong flush
• Time to First Bloom: Fast – often flowers within its first season from seed
• Flower Appearance: Four-petalled, crossed flowers in warm yellow to orange, carried in tight spikes on the stems
• Edibility: Ornamental only – wallflowers are not eaten (they contain cardiac glycosides)

Detailed Blooming Overview

The Afghan wallflower throws up dense, colourful spikes of small crossed flowers in vivid yellow and orange, often lightly fragrant and long-lasting. It flowers hard in spring and early summer and is a favourite of bees and butterflies.

Flower Characteristics

• Four petals in a crossed shape, in yellow to orange, packed along upright stems.
• Often carrying a light, sweet scent.

Bloom Care & Thinning

• Encouraging bloom: Deadhead spent spikes to keep new flowers coming through the season.
• Pollination: The bright flowers draw in bees and butterflies.
• Safety: Like other wallflowers, this species contains cardiac glycosides – enjoy it as an ornamental, not as an edible flower.
