A grand display for every garden

The Giant Flower Sunflower is the perfect ally for creating striking focal points in your planting schemes. With blooms reaching 30 cm across perched on 2-metre stems, it towers majestically over tall borders and creates unique visual perspectives.

Ideal for keen gardeners wanting to impress their visitors, professional landscapers looking for high-impact varieties, or schools and activity centres for spectacular teaching projects. Its extended flowering into autumn guarantees a lasting decorative effect, while its bright colours brighten the end of summer.

Technical characteristics and adaptability

This single-stemmed variety has the advantage of concentrating all its energy into one monumental flower, creating an even more spectacular effect. Its natural sturdiness lets it withstand strong winds thanks to its deep root system and thick stem.

Particularly suited to poor soils, this sunflower is content with ordinary ground that is rich in humus and well drained. It tolerates neutral to alkaline pH and thrives in conditions other giant flowers would struggle with. Its drought resistance once established makes it a sound choice for eco-friendly gardens.

Sowing and growing

Sow from March to June depending on your region, either straight into the ground or in pots for transplanting. Sow 2-3 cm deep, allowing 50 cm minimum between plants so the roots and stem can develop properly.

Regular watering is essential for the first six weeks, the crucial development period. After that the plant becomes self-sufficient thanks to its deep root system. Discreet staking may be needed in windy spots to stop the stem snapping under its heavy flower.

Expert advice and successful pairings

To maximise visual impact, place your sunflowers at the back of a mixed border, alongside cosmos, rudbeckias or dahlias for a harmony of warm colours. Pairing them with ornamental grasses such as miscanthus creates a very modern contrast of textures.

Professional tip: sow in several batches a fortnight apart to stagger flowering and extend the display. The ripe seeds make excellent food for birds in autumn, contributing to the biodiversity of your garden. Avoid soils that are too rich, as they encourage foliage at the expense of flowering.
