Key features:

• Tailored for tubs, troughs, borders, and window boxes, meaning the species stay compact and graceful
• Native wildflower species that promote biodiversity and support local habitat
• Extended session of bloom, offering vibrant colours for the summer months

Meadow Buttercup (Ranunculus acris)
– Bright yellow flowers which provide early nectar for pollinators.

Lady’s Bedstraw (Galium verum)
– Mat-forming perennial. Good for soil stability and nectar.

Selfheal (Prunella vulgaris)
– Low-growing perennial. Attractive to bees and butterflies.

Yarrow (Achillea millefolium)
– Hardy perennial. Aromatic foliage and long flowering season.

Tufted Vetch (Vicia cracca)
– Climbing wildflower. Nitrogen fixer and pollinator-friendly.

Bird’s-foot Trefoil (Lotus corniculatus)
– Low-growing. Excellent nectar plant and important for butterflies.

Yellow Rattle (Rhinanthus minor)
– Semi-parasitic on grasses. Reduces grass vigour, encouraging flowers.

Ribwort Plantain (Plantago lanceolata)
– Hardy perennial. Long flowering period and resilient in meadows.

Salad Burnet (Sanguisorba minor)
– Perennial herb. Drought-tolerant with attractive red-green flowers.

Kidney Vetch (Anthyllis vulneraria)
– Improves soil health. Key food plant for the Small Blue butterfly.

Wild White Clover (Trifolium repens)
– Nitrogen fixer; boosts soil health and attracts pollinators.

Cowslip (Primula veris)
– Early-flowering; important nectar for spring pollinators.

Black Medick (Medicago lupulina)
– Early-flowering; fixes nitrogen and provides nectar for bees.

Meadow Vetchling (Lathyrus pratensis)
– Nitrogen fixer; climbing plant that supports bees.

Common Vetch (Vicia sativa)
– Nitrogen fixer; provides nectar and supports soil fertility.

Ideal for window boxes, balcony tubs, container gardens, raised troughs, narrow border fronts, or small rockeries. Despite their modest size, these wildflowers support bees, hoverflies, butterflies and other beneficial insects, adding ecological value to urban spaces and helping to stitch nature into our everyday surroundings.

Sow directly into pots, window boxes or containers in early spring or autumn. Use a low-nutrient, free-draining compost or soil mix. Lightly rake or loosen the surface, then scatter seeds evenly across the top. Press down gently to ensure good contact with the soil, do not cover with compost or soil.

Keep the surface moist during germination, especially in dry spells. Seeds usually germinate within 2–4 weeks, depending on temperature and moisture levels. Some species may flower in the first year, while others will establish and bloom more fully in the second.

Once established, these wildflowers need very little attention. Avoid feeding or overwatering, as this encourages leafy growth over flowers. After flowering, trim back in late summer or autumn, leaving cut stems for a few days to allow any seeds to fall and re-sow naturally.

Q1: Will these wildflowers compete with my existing container plants or border shrubs?

A: As this mix uses compact species, they are unlikely to overpower neighbours when sown appropriately. Be sure to provide sufficient root space and avoid over-fertilising, which can favour more vigorous plants over wildflowers.

Q2: Is this mix suitable for full shade or very dry soils?

A: This mix performs best in sunny to partially sunny positions with reasonably consistent moisture. In deep shade or very dry substrates, germination and flowering may be weak.

Q3: Can I sow directly into pots already in place, or should I start in fresh compost?

A: You can sow into existing containers if you reduce the topsoil volume and loosen the surface. However, using a fresh or refreshed soil/compost base gives seedlings a better start.

Q4: How long until I see flowers?

A: Some annual or biennial species will flower in the first year; many perennials may take until the second season to reach full bloom potential.
