Craspedia globosa SolarPop

Craspedia globosa SolarPop Seeds

( Billy Buttons / Drumstick Flower)

Craspedia globosa SolarPop is the grade selection of Billy Buttons developed by Benary, one of the world’s most respected ornamental plant breeding. SolarPop produces large, golden flower heads that serve as a trendy highlight in every flower bouquet. The variety attracts many beneficial insects and is suitable for pots, containers, and the landscape as well as professional cut flower production.

Craspedia globosa is native to Australia and New Zealand, where it is found inland in dry woodlands, scrublands, and grasslands across the eastern and southeastern mainland. The plant is highly popular in floristry due to its floral form and long vase life, and its ability to retain color when dried makes it highly desirable for dried arrangements.

Craspedia goes by many names — Billy Balls, Billy Buttons, woollyheads, and drumsticks — all referencing the plant’s quirky appearance. Its most notable characteristic is the vibrant, ball-shaped flower clusters forming at the top of each stem, made up of tiny, symmetrically arranged florets. Craspedia retains its color for a year or more when dried, making it a popular choice among floral designers for dry arrangements.

The spherical heads dry almost exactly as they appear fresh, retaining their sunshine-yellow color for years — fading gradually to a warmer mustard over time, which has its own appeal. This makes Craspedia uniquely valuable: a single sowing produces stems that contribute to fresh summer arrangements and dried winter wreaths alike, all from the same harvest.

Large, globe-shaped flowers are held high on wiry stems above mounds of grass-like foliage. Silvery leaves contribute to the plant’s overall visual appeal in the landscape, while the long vase life of Billy button flowers makes them ideal for cutting and use in dried floral crafts.

In Kuwait’s growing season, Craspedia globosa SolarPop is sown in autumn, establishing through the cool winter months, then naturally triggered to flower as day lengths lengthen past 12 hours from late March onward. The combination of Kuwait’s high light intensity and warming spring temperatures creates ideal conditions for abundant, quality stem production through spring and into the early summer months.

Variety Details

• Craspedia globosa SolarPop is bred by Benary and belongs to the Asteraceae family, native to Australia and New Zealand.

Seed Germination

• Radicle emergence is expected in 4 to 7 days.
• Cover the seed with vermiculite or substrate after sowing.
• Sow 3 seeds per plug cell
• Media pH 5.8 to 6.2,
• Temperature on days 1 to 7: 20 to 22 degrees Celsius.
• Use only warm water above 18 degrees Celsius for irrigation throughout germination.
• Begin with wet moisture level for the first 7 days, then reduce to moist.
• Maintain humidity at 95 to 100 percent until day 7, then reduce to 40 to 60 percent.
• Protect seedlings from direct sunlight until they are well established.
• For home gardeners:
• sow 2 to 3 seeds per small pot or cell using a moist, well-drained seed-starting mix.
• Cover seeds lightly with vermiculite or fine substrate — covering is necessary.
• Place in a warm location at 20 to 22 degrees Celsius.
• Keep consistently moist with warm water.
• Germination occurs in 4 to 10 days.
• Once seedlings emerge, move to a bright location protected from harsh direct midday sun until roots are established.

Growing Tips

• During growing-on, maintain media pH 5.8 to 6.2,
• Temperature: 14 to 16 degrees Celsius days, 12 to 14 degrees Celsius nights for two weeks after transplanting.
• High light levels reduce the overall crop time and promote early flowering.
• No growth regulators are required — growth is managed through temperature and moisture control.
• Craspedia globosa plants thrive in full sun and well-drained, non-acidic, gritty soil.
• These flowers are adaptable to poor soil conditions and drought.
• Billy buttons require at least 6 hours of direct sunlight to thrive and bloom.
• Space plants 30 to 40 cm apart.
• Water sparingly once established — Craspedia is notably drought tolerant and does not require rich soil or frequent fertilization. Avoid waterlogging at all times, as the roots are susceptible to rot in saturated conditions.
• Cut Craspedia stems when the spherical head is fully formed and the yellow color is at its most vivid — before any browning of the outermost florets occurs.
• Strip all leaves from the stem before placing in a vase.
• Vase life is typically 7 to 14 days fresh.
• The rigid stems and perfectly round heads create striking contemporary arrangements when grouped in multiples in a simple cylindrical vase.

For drying:

• harvest at full bloom on a dry day.
• Bundle stems together and hang upside down in a dry, shaded location with gentle air circulation.
• Flowers dry completely in 7 to 10 days and retain their golden color for a year or more.

Gulf Planting Season

• Sow indoors in protected nursery conditions: September through November.
• Transplant to containers, cutting garden rows, or borders: October through December.
• Expected flowering: March through May, as day lengths exceed 12 hours and temperatures rise.
• Note: Craspedia globosa SolarPop is a facultative long-day plant.
• Flower initiation requires day lengths above 12 hours, which
• Kuwait reaches around late March. Autumn sowing allows vegetative establishment through the shorter winter days, with natural flowering triggered as days lengthen through spring.

Garden and Floral Uses

• Craspedia globosa fits into various garden designs and uses cutting garden rows for fresh and dried stems, modern borders
• where the round yellow flowers provide a striking graphic accent, rock gardens and low-maintenance landscape plantings.
• The spherical flowers add texture, color, and a graphic accent to both modern and rustic bouquets.
• Billy Balls are prized as a cut flower, adorning bouquets and arrangements with their whimsical and playful appearance. Their unique globe shape adds a dimensional, sculptural element that few other flowers can provide.
• In the Gulf garden, Craspedia globosa SolarPop is invaluable as a spring-season cut flower of unusual character — the perfectly geometric golden spheres on clean, leafless stems bring a contemporary, architectural quality to mixed bouquets.
• Combine with Ranunculus, Lisianthus, Anemone, and ornamental grasses for sophisticated spring arrangements where the golden drumsticks anchor the composition with color and form.
• The dried stems are equally valuable, providing year-round golden accents in wreaths, dried flower arrangements, and home decoration long after the fresh season has passed.
