The “billy plant” is formally known as Craspedia globosa and is commonly referred to as Billy Buttons or Drumstick Flower. It is recognized for its unique spherical, bright yellow flower heads that sit atop tall, slender stems. This distinctive appearance makes it a popular choice for garden displays and floral arrangements, particularly for dried flower crafts. Native to regions of Australia and New Zealand, Craspedia globosa is often grown as an annual in many climates, though it can be a perennial in warmer zones.
Starting Billy Plants from Seed
Starting Billy Buttons from seed can be done indoors or directly outdoors. For most regions, sowing seeds indoors approximately four to eight weeks before the last expected frost date is recommended to allow sufficient time for germination and growth. When starting indoors, use a quality seed starting mix and sow the seeds on the surface, covering them lightly with a thin layer of peat moss or sand, as they require some light for germination.
Maintain consistent moisture in the planting medium during germination, which takes about 14 to 21 days. An ideal germination temperature is around 70°F (21°C). Once seedlings develop at least two sets of true leaves and have been hardened off, they are ready for transplanting into garden beds, ensuring adequate spacing of about 10 to 24 inches between plants.
Ideal Growing Environment
Billy Buttons thrive in full sun, requiring at least six hours of direct sunlight daily for robust growth and flowering. Insufficient light can result in reduced blooming. These plants prefer well-draining soil and are adaptable to a range of soil types, including sandy, loamy, or even clay soils. They can tolerate various soil pH levels, from acidic to alkaline.
While drought-tolerant once established, consistent moisture is beneficial. However, it is important to avoid waterlogged conditions, as this can be detrimental to the plant’s health. Billy Buttons tolerate heat and perform well in warm climates. They are hardy perennials in USDA Zones 8 through 11 and are grown as annuals in cooler zones.
Ongoing Care and Maintenance
Established Billy Button plants require minimal ongoing care. They are not heavy feeders, but a slow-release fertilizer can be applied during the growing season to support healthy growth, or compost and aged manure can be incorporated into the soil. Deadheading spent blooms encourages the plant to produce more flowers throughout its blooming period.
General garden upkeep involves monitoring for any yellowing foliage, which can be removed to maintain plant vigor and appearance. Billy Buttons do not require extensive pruning beyond this. Their low-maintenance nature makes them a good choice for gardeners seeking resilient plants.
Harvesting and Preserving Billy Buttons
Billy Buttons are suitable for both fresh and dried floral arrangements. For fresh cut flowers, harvest the stems when the flower heads are fully formed and firm, but before the tiny individual florets begin to open. Cut the stems at the desired length, near the base of the plant.
To preserve Billy Buttons for dried arrangements, harvest them when the flowers are fully open but still firm, as they retain color and shape well. Remove any foliage from the stems. Gather small bunches of stems and hang them upside down in a dark, dry, and airy location. This drying process takes several weeks, resulting in long-lasting, vibrant yellow spheres.
Addressing Common Issues
While resilient, Billy Buttons can encounter a few common issues. Leggy growth, characterized by stretched stems and sparse foliage, indicates insufficient light; ensuring the plants receive full sun can prevent this. Poor air circulation combined with excessive moisture can lead to fungal diseases like powdery mildew, so proper plant spacing and well-draining soil are important preventative measures.
Pests such as aphids, spider mites, snails, and slugs can affect Billy Buttons. Aphids and spider mites can be managed with insecticidal soap or a strong spray of water. Snails and slugs can be deterred with organic baits or by removing them manually, especially during cooler, damp periods. Maintaining a healthy growing environment helps the plants resist most problems.
