Many Colours Red: Five Dramatic Red Flowers for Your Garden

Red commands attention like no other hue. Launching our color-focused series, here are five red cultivars that deliver drama, structure, and seasonal interest.

1. Geum 'Mrs Bradshaw' (syn. 'Bell Bank', 'Avens')

Herbaceous perennial with double red flowers on wiry stems (May–September) + attractive ground cover. Front-of-border placement for sun access. Shelter from weathering. Most soils except extremes of wet/dry/heavy clay. Enrich with compost.

2. Papaver 'Goliath' (Oriental Poppy)

Huge papery red flowers with black centers—early summer showstopper. Foliage dies back post-flower (cut back for potential rebloom). Sun but not extreme heat/humidity. Plant crown few inches below surface. Avoid clay; ensure drainage. Near-neutral pH.

3. Kniphofia uvaria (Red Hot Poker / Torch Lily)

Striking red-tipped spikes (July–September) resembling tiki torches. High light needs; stake in exposed sites. Drought/heat tolerant. Trim base leaves post-bloom; cut flower stems down.

4. Dahlia 'Bishop of Llandaff' (AGM)

Bronze-purple foliage contrasts with dark red double flowers (late summer–autumn). Full sun, well-drained soil. Sunny sheltered spot, rich loam. Water + deadhead regularly. In mild areas, tubers can overwinter in ground; else lift after frost, store dry/frost-free until spring.

5. Euphorbia griffithii 'Fireglow'

Carmine red with orange core (late spring–early summer). Longer-lasting than poinsettia relative. Adaptable: sun/part shade, exposed/sheltered, most pH. Dense humus-rich soil preferred—light soil encourages invasiveness.

Red done right: bold, not brutal.
