Bracteantha ‘Granvia® Gold’: Supersized Color from Spring to Fall
Bracteantha ‘Granvia® Gold’ or currently classified as Xerochrysum bracteatum ‘Granvia® Gold’, a member of the Asteraceae family, is not your average strawflower. This standout cultivar shines with oversized golden blooms that almost glow in the sun. What makes ‘Granvia® Gold’ exceptional isn’t just its color—it’s the texture, size, and stamina. With thick, papery petals and a center that shifts to orange as the bloom ages, this variety creates a high-impact display that lasts from spring through fall.
Whether in a flower bed or a patio container, this plant performs consistently across a range of climates. Bracteantha Granvia Gold was bred by Suntory. They developed this cultivar, known for its mildew resistance, vigor, and large, golden flowers. Suntory Flowers is a Japanese company that specializes in plant breeding and seed production.
Understanding the Naming: Xerochrysum vs. Bracteantha
You may come across this plant listed under different scientific names—Xerochrysum bracteatum, Bracteantha bracteata, or even Helichrysum bracteatum. All three refer to the same species commonly known as Strawflower. Historically, it was first classified as Helichrysum, then moved to the genus Bracteantha. As botanical research progressed, the correct and currently accepted name became Xerochrysum bracteatum. Despite this, the name Bracteantha is still widely used in the horticultural trade and plant tags, which can lead to some confusion. For clarity and scientific accuracy, Xerochrysumshould be used when referring to the modern classification of this long-loved ornamental plant.
Why Bracteantha ‘Granvia® Gold’ Stands Out
Bracteantha ‘Granvia® Gold’ has flowers up to twice the size of typical strawflowers. The bright yellow blooms, layered with pointed petals like rays of sunshine, rise above dense, green foliage on strong stems that don’t flop. Even as the weather turns hot, humid, or windy, this plant keeps blooming—holding its form and color where others fade.
More than just ornamental, this plant also offers practical benefits. It resists mildew, tolerates urban pollution, shrugs off deer, and attracts pollinators. Use it in containers, borders, or cut-flower arrangements. Dried flowers from ‘Granvia® Gold’ also make stunning additions to crafts or potpourri.
Bloom Time:
Granvia® Gold plants typically start blooming in late May and continue to flower prolifically through the summer and well into the fall, providing long-lasting color from spring’s warmth to autumn’s cool.
How to Grow Bracteantha ‘Granvia® Gold’
Light
This plant thrives in full sun. Give it at least 6 to 8 hours of direct sunlight each day for the most vibrant blooms and compact growth.
Soil
Provide well-draining soil with a neutral to slightly acidic pH between 6.0 and 7.5. It tolerates average garden soils but resents soggy conditions.
Watering
Water regularly, especially during hot spells, but allow the top inch (2.5 cm) of soil to dry out between waterings. Avoid overwatering, as root rot can develop in poorly drained spots.
Fertilizing
Feed monthly with a balanced flower fertilizer during the growing season. A slow-release fertilizer at planting helps maintain vigor, but additional feeding every 2 to 4 weeks with a water-soluble formula will maximize bloom production.
Pruning
Deadhead faded flowers regularly to promote continuous blooming. Pinching early in the season may encourage bushier growth but is generally not required due to the plant’s naturally compact habit.
Bracteantha ‘Granvia® Gold’ Size and Habit
- Height: 45–76 cm (18–30 inches)
- Spread: 45–61 cm (18–24 inches)
- Spacing: 30–41 cm (12–16 inches)
- Growth Habit: Upright and bushy
- Bloom Time: Spring through fall
- Life Cycle: Short-lived perennial in Zones 8–11; grown as an annual elsewhere
‘Granvia® Gold’ grows moderately fast and flowers early. The large blooms stay intact for weeks and retain their bold structure in both fresh and dried arrangements. Expect consistent color and performance from June through September, even under stress.
Propagation of Bracteantha ‘Granvia® Gold’
While technically possible to propagate by cuttings, this cultivar is protected and may have propagation restrictions. For home use, purchase nursery-grown starts. If taking cuttings, do so from soft wood in spring or early summer. Provide bottom heat and high humidity to encourage rooting.
Pests and Diseases
This strawflower offers excellent resistance to mildew, a common issue for bracteantha species. Its tough foliage rarely suffers from pest damage, though aphids or whiteflies may occasionally visit. Treat infestations early with insecticidal soap or neem oil. Avoid overhead watering and overcrowding to reduce fungal risk.
Where to Plant Bracteantha ‘Granvia® Gold’
Use this showy strawflower in:
- Garden beds and borders
- Mixed containers and patio pots
- Hanging baskets
- Pollinator gardens
- Cut flower gardens
In containers, it functions well as a centerpiece (“thriller”) or filler depending on your design. Combine it with trailing plants like calibrachoa or verbena and upright grasses for a balanced composition. Expect to water container-grown plants more frequently than those planted in beds.
Care Tips for Bracteantha ‘Granvia® Gold’
- Sunlight: Always plant in full sun for best results.
- Soil: Use loose, well-drained soil. Amend with sand or compost if necessary.
- Watering: Water when the top 2.5 cm (1 inch) of soil feels dry. Avoid overwatering.
- Humidity: Prefers dry to moderate humidity. May struggle in extreme tropical climates.
- Fertilizer: Monthly balanced fertilizer. Additional foliar feeding during flowering boosts results.
- Wintering: In Zones 8 and warmer, mulch in late fall. In cooler zones, treat as an annual or overwinter indoors.
