Helianthus annuus 'Waooh!' is a Half-Hardy Annual and the most floriferous variety in the Bishy Barnabee's sunflower range — a compact, heavily branching, pollen-free cultivar bred specifically for maximum flower production over a long season, and selected for its exceptional performance both in the garden and as a cut flower. It is the most distinct variety in the range, offering a fundamentally different growth habit and use pattern from the taller single or branching varieties.

What 'Waooh!' Adds to the Range: The existing Bishy Barnabee's sunflower range covers the full tonal spectrum from golden pompom (Teddy Bear) through blazing bicolour (Ring of Fire), pure crimson (Red Sun), near-black velvet (Chocolate), and luminous cream (Vanilla Ice). 'Waooh!' adds something different entirely — not a new colour, but a new use pattern. Where the other varieties are statement plants producing flowers over a defined summer period, 'Waooh!' is a long-season cutting machine that keeps producing from July through to October, extending the range's usefulness deep into autumn and providing an essentially inexhaustible supply of classic golden-yellow stems throughout the season.

Pollen-Free Growing: The pollen-free characteristic of 'Waooh!' is the result of deliberate breeding selection — the anthers of the flower produce no viable pollen, meaning the central disc remains clean, dark, and visually striking without the yellow dusting that conventional sunflowers produce as they mature. This makes the flowers longer-lasting in the vase (pollen production is part of the natural ageing process of the flower), easier to arrange without mess, and suitable for use in situations where pollen-producing flowers would be problematic.

Container Growing: At 80–90cm, 'Waooh!' is the most practical sunflower in the range for large containers — a substantial pot of at least 30–40 litres filled with good-quality compost will support a productive plant through the season with regular watering and fortnightly feeding. This makes it the most accessible variety in the range for gardeners without dedicated borders.

'Waooh!' is grown in the same way as the other sunflower varieties in the range, with the additional option of closer spacing to create a temporary flowering hedge effect given its compact, bushy habit.

How to Sow:
Sow indoors from late March to April in individual 7–9cm pots, one seed per pot approximately 1–2cm deep. As with all sunflowers, individual pot sowing is strongly recommended — the taproot develops quickly and resents disturbance at transplanting. Maintain a temperature of 18–22°C. Germination typically occurs within 7–10 days. For direct outdoor sowing in the final position, wait until after the last frost and sow from late April to May.

Transplanting:
Plant out after the last frost from late May to early June after a thorough hardening-off period. For border use, space plants 30–40cm apart — closer than the taller varieties, reflecting 'Waooh!'s compact habit. For a temporary flowering hedge effect, plant in a double staggered row at 25–30cm spacings. Full sun produces the most prolific flowering — in partial shade the plant will still flower but less abundantly. No staking required in any position.

Ongoing Care:
Water consistently during dry spells, particularly during the establishment period and when plants are in active bud formation. Feed with a balanced liquid fertiliser fortnightly from bud formation. Unlike the taller branching varieties where pinching encourages lateral stems, 'Waooh!' branches naturally and profusely without intervention — simply harvest stems regularly as they come into flower to encourage continuous production. The more you cut, the more it produces.

Container Growing:
Use a container of at least 30–40 litres for a productive plant. Fill with good-quality multipurpose or peat-free compost, water thoroughly at planting, and maintain consistent moisture throughout the season — containers dry out more rapidly than borders and 'Waooh!' will reduce flowering noticeably if water-stressed. Feed every two weeks with a balanced liquid fertiliser from July onwards.

The classic golden-yellow of 'Waooh!' is one of the most versatile and most welcoming colours in the late summer garden — warm, cheerful, and naturally harmonious with a wide range of companions from the range:

• 🧡 Calendula 'Art Shades Mixed': The Warm Harmony. Calendula Art Shades planted in front of 'Waooh!' creates one of the most naturally satisfying warm-toned combinations in the cottage garden — the deep apricot, amber, and cream tones of the Calendula stepping up through the warm register to the rich golden-yellow of the sunflower above. The combination reads as a single, extended warm palette rather than two separate plants, and the long flowering season of both — Calendula from spring and 'Waooh!' from July — means the combination is sustained and generous for months. Both are outstanding for pollinators, and both provide an essentially endless supply of cut stems throughout the season.
• 🌼 Borage: The Blue Complementary. The electric blue of Borage stars at mid-height against the golden-yellow of 'Waooh!' is one of the most vivid and most naturally pleasing complementary contrasts in the summer garden — warm and cool, round and star-shaped, bold and delicate, each making the other appear more intense by proximity. At 80–90cm 'Waooh!' sits above the Borage at just the right height to create a layered planting of genuine depth, and the combination is as effective in a mixed vase arrangement as in the border. Both are outstanding for pollinators and both flower over a long summer season.
• 🌸 Ammi Majus: The White Cloud. A cloud of white Ammi Majus lace around the golden 'Waooh!' flowers is one of the most classic and most universally admired summer cutting garden combinations — the delicate, airy white umbels providing the perfect foil for the bold, round, golden sunflower heads. In the border the effect is of sunshine breaking through white mist; in the vase it is of warmth and freshness combined in a single, effortlessly beautiful arrangement. The pollen-free quality of 'Waooh!' means this combination is as practical as it is beautiful — no pollen to contend with in the vase, just clean golden stems and white lace.
• 🌀 Echinops 'Veitch's Blue': The Architectural Contrast. The cool, spiky, steel-blue globe heads of Echinops alongside the warm golden flowers of 'Waooh!' is a combination with deep roots in the Arts and Crafts garden tradition — warm gold and cool blue-grey, round and spiky, generous and architectural. At similar heights the two plants work as genuine border companions rather than simply background and foreground, and the contrast between the sunflower's classic open face and the Echinops's perfectly spherical globe creates a conversation of form and colour that is genuinely sophisticated. Both dry beautifully, making the combination as valuable in a dried autumn arrangement as in the living summer border.

Sow indoors from late March for golden flowers from July — then enjoy the most sustained, most generous flowering display of any sunflower in the range, right through to the first October frosts.
