Pycnosorus Globosus
Often called the "Billy Button" or "Drumstick," this quirky Australian native looks like it jumped straight out of a Dr. Seuss book. With its perfectly spherical, golden-yellow flower heads perched on top of long, slender stems, it has become a darling of the modern floral world. Whether swaying in a breezy meadow or standing tall in a minimalist vase, its cheerful personality is hard to miss.
The Billy Button gained worldwide fame during the 2000 Sydney Olympics, where it was featured prominently in the victory bouquets presented to medal-winning athletes!
To grow Pycnosorus Globosus, also known as Billy Buttons or Drumsticks, you can follow these steps:


To fertilize this plant, it is necessary to use a slow-release fertilizer that has equal parts of nitrogen, phosphorus, and potassium. Begin the fertilization process during the growing season, which is from spring through summer. Apply the fertilizer once every month. Scatter the fertilizer evenly around the plant, and make sure it doesn't touch the leaves or stems to avoid burning. Water the plant thoroughly after fertilizing.
The ideal soil to use for this plant is a well-draining and nutrient-rich mixture that is slightly acidic. It should contain a mix of organic materials such as peat moss, compost, and leaf mold, as well as coarse sand or perlite to improve drainage. The soil should also be kept consistently moist but not waterlogged, as this can lead to root rot. Additionally, this plant prefers a soil pH of around 6.0 to 6.5, so acidifying agents such as sulfur or aluminum sulfate can be added if necessary.
To propagate this plant, you will need to carefully detach a stem cutting from the parent plant using a sharp, sterile knife. It is important to choose a stem that is healthy and free of any damage or disease. The cutting should be around 10cm in length and have at least one node where leaves emerge.
Once you have your cutting, remove the lower leaves from the stem, leaving a couple of leaves near the top. Dip the cut end of the stem in rooting hormone powder to encourage rooting, then plant the cutting in a pot filled with well-draining soil. Water the cutting lightly and cover it with a clear plastic bag or dome to create a humid environment that will help encourage root growth.
Place the pot in a warm, bright location but out of direct sunlight. Check the cutting regularly and mist it lightly with water if the soil starts to dry out. After a few weeks, you should start to see new growth and signs that the cutting has rooted. Once the plant has established itself and is growing well, you can transplant it to a larger pot or into your garden.
