Our Summer Bedding Collection

Our extensive selection features classic favourites and contemporary varieties that deliver months of continuous, vibrant colour with minimal fuss.

Choose from hardy geraniums in an array of colours including zonal varieties in white, pink, red, orange, salmon, purple and striking bicolours, plus trailing ivy geraniums perfect for cascading displays. Petunias remain perennially popular, with standout varieties like 'Night Sky', 'Johnny Flame', and the eye-catching 'Sweetunia Miss Marvellous' creating spectacular hanging basket displays.

For sun-loving gardeners, our osteospermums (African Daisies) bring bold blooms in magenta, yellow, pink, orange and white, including unique varieties like 'Picasso' and 'White Spoon'. Complement these with delicate campanulas (bellflowers) in lavender, white, pink and purple, or add height and movement with verbena varieties including the architectural Verbena bonariensis and compact 'Lollipop'.

Our New Guinea impatiens provide reliable colour for partial shade, whilst nemesia, calibrachoa and lobelia offer excellent filler plants for mixed containers and flower beds.

We also stock three convenient colour-themed bundles—Elegant White, Royal Purple, and Pretty in Pink collections—each containing 10 carefully selected plants for effortless coordinated displays. For added interest, explore sweet peas to attract pollinators, ornamental grasses for texture, and scented pelargoniums in lemon and orange varieties, perfect for sensory gardens, window boxes and patio pots.

These annual plants and hardy annuals are ideal for creating wildlife-friendly bedding schemes that not only look beautiful from early summer but also support bees and butterflies throughout the season.​

Frequently Asked Questions

When should I plant summer bedding plants?
Plant summer bedding outdoors from late May to early June once the risk of frost has passed. Planting too early risks frost damage to tender plants, whilst planting after early June may limit flowering time. Always harden off plants gradually if they've been kept in protected conditions, and ensure soil temperatures have warmed sufficiently for root establishment.​
How do I keep summer bedding plants flowering all season?
Regular deadheading is essential to prolong flowering by preventing plants from setting seed and redirecting energy into new blooms. Water consistently—daily during hot spells, especially for containers and hanging baskets which dry out quickly. Feed every two weeks with a balanced liquid fertiliser to encourage vigorous growth and abundant flowers throughout summer. For plants that have gone over, cut back to fresh growth to stimulate a second flush of blooms.
Which summer bedding plants are easiest to maintain?
Geraniums (pelargoniums) are amongst the most low-maintenance choices, requiring only modest deadheading, tolerating drought well, and resisting slug damage. Begonias adapt to most conditions and need minimal attention, making them ideal for busy gardeners. Nasturtiums and calendulas also require little fuss, whilst petunias, verbena and lobelia demand more regular deadheading to maintain their display. For containers, choose drought-tolerant varieties if you're unable to water daily during summer.​
