Berger's Record: Bright Red Spikes on a Compact Plant

Berger's Record is a semi-cactus dahlia with bright red flowers and the kind of spiky, architectural form that makes cactus types so distinctive. The petals are long, pointed and recurved, giving each 15cm bloom a starburst quality that stands out against softer flower shapes in a border.

At 90cm with a narrow 40cm spread, it's a compact, upright plant that doesn't take up much room. The stems are strong, the flowers are held well above the foliage, and the whole plant has a tidy habit that suits smaller gardens and containers. It flowers from July to November.

What Goes with Berger's Record

Bright red semi-cactus spikes look best against contrasting shapes. Plant alongside Golden Sceptre (yellow ball, 90cm) for a classic red-and-gold combination where the spiky cactus form plays against the tight sphere. White Swan (white decorative, 120cm behind) provides a clean backdrop. For a moody scheme, Dark Spirit (near-black, same height) deepens the red tones.

Frequently Asked Questions

What's a semi-cactus dahlia?

A dahlia with petals rolled or quilled for at least half their length, giving a spiky, architectural appearance. The rolled petals shed rain better than flat decorative types. Our types of dahlias guide explains all the classifications.

Will Berger's Record grow in a pot?

At 90cm with a narrow spread, it works well in a container of at least 30cm across. The upright habit and moderate height make it genuinely container-friendly. Feed fortnightly from June. Our container guide has the detail.

Is Berger's Record good for cutting?

The strong, upright stems and 15cm flowers make it a good cutter. The spiky semi-cactus form adds texture to arrangements that rounder flower shapes lack. Cut only fully open blooms. Full growing advice in our dahlia growing guide.
