Perfect for pots

Dahlia 'Cactus Mixed' brings a mixed collection of spiky cactus dahlias for bold borders to summer borders and cutting gardens, with bold flowerheads held on sturdy stems. Whether planted in drifts or dotted through mixed beds, the blooms add instant impact and keep coming through the warm months.

Once established, this clump-forming dahlia typically reaches 90–120 cm, producing plenty of long stems for cutting. Regular picking and deadheading encourages a steady succession of flowers from midsummer into autumn.

Start tubers in a frost-free place in spring, or plant outside once the risk of frost has passed. Choose a sunny, sheltered spot in fertile, humus-rich, well-drained soil, and enrich the planting area with compost for best results.

Water during dry spells, especially while buds form, and feed every two to three weeks through the flowering period. Taller plants benefit from discreet staking, and removing faded blooms keeps the plant productive and tidy.

Perfect for borders, patio pots and cutting gardens, dahlias are also pollinator-friendly in single-flowered forms. Lift and store the tubers after the first frosts in colder areas to enjoy an even better display the following year.

Begonia 'Pendula Red' (Double) produces cascading double red blooms that sit above glossy green foliage, bringing instant theatre to shaded patios, doorstep pots and hanging baskets. The blooms are richly textured and long-lasting, making this a go-to choice for summer colour where sun-loving plants struggle.

Tuberous begonias develop compact, bushy growth with plenty of flowers from early summer through to the first frosts. They’re particularly effective in containers, where you can show off the blooms at eye level and keep growth even with regular watering and feeding.

Start tubers indoors in spring or plant outside once frosts have passed. Choose fertile, well-drained soil or a free-draining compost, and position in bright shade or partial shade away from hot afternoon sun and drying winds. Plant the tuber shallowly with the hollow side facing up.

Water carefully until growth is established, then keep the compost evenly moist but never waterlogged. Feed every two weeks during flowering for the best display, and remove spent blooms to encourage continuous performance. Provide shelter from heavy rain and strong winds to protect the flowers.

Perfect for shaded borders, patio displays and hanging baskets, begonias also add late-season impact when paired with ferns, heucheras and foliage plants. Lift and store tubers after the first frost in colder areas, ready to restart next spring.

Dahlia ‘Seduction’ is an alluring decorative variety known for its elegant pink and purple picotee petals. Each bloom features a pale, milky-white base that is delicately edged with deep violet-pink, creating a defined and sophisticated outline.

The plant is robust and floriferous, producing a high volume of medium-sized flowers throughout the season. The distinct colouring of the petals gives the blooms a three-dimensional quality, making them pop against the dark green foliage.

Plant in full sun to partial shade, in soil that has been improved with compost. This variety is excellent for adding detail and intricacy to a border without overwhelming other plants with solid blocks of colour.

Keep the plant well-watered during dry spells and stake if necessary to support the weight of the flowers. Deadhead faithfully to ensure a display that lasts well into autumn, and protect the tubers from frost during winter.

A brilliant choice for romantic cottage gardens, ‘Seduction’ draws the eye with its intricate detailing and pairs beautifully with deep purple flowers like Salvia ‘Caradonna’ or dark-leaved Heucheras.
