Direct from T&M’s own breeding, this duo of sensational annuals make perfect patio partners. Bred for a compact, multi-branching habit, they will produce neat mounds of fresh- green foliage. From summer right through to November you can enjoy the radiant, golden blooms of SunBelievable™ 'Golden Girl' and her bicolour sister plant, SunBelievable™ 'Brown Eyed Girl'. Being completely sterile, you’ll notice that the blooms go on and on, without pausing to set seed, so you can afford to take plenty of cut flowers. Both varieties are easy to grow, and loved by bees and butterflies. Our Sunflower SunBelievable™ Duo is ideal for filling patio pots, beds and borders, with long-lasting colour. Height and spread: 60cm (24").

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

How to Grow
When all risk of frost has passed, gradually acclimatise sunflower plants to outdoor conditions before planting into containers of good quality compost. Alternatively, plant them directly into sunny borders in fertile, well drained soil.
