Gardener's HQ Guide to Growing Chrysogonum virginianum
Chrysogonum virginianum, often referred to by its common names Goldenstar or Green and Gold, is a charming perennial plant beloved by many gardeners.
It usually grows about six to twelve inches tall (15-30 cm) and spreads 12-18 inches wide (30-46 cm). This means it won't overpower other plants in your garden but will contribute to a balanced and harmonious composition.
One of the Goldenstar's most distinguishing features are its star-shaped, golden-yellow flowers that bloom from late spring to early summer.
Each flower has five petals that beam like a tiny sun from its heart. The foliage is a deep green, ovate or heart-shaped, adding a contrasting texture to your garden even when the plant is not in bloom.
Gardeners appreciate the Chrysogonum plant for its relatively easy care and its hardy nature. This plant is suitable for USDA zones 5-9 and it receives a hardiness rating of H5-H6 from the Royal Horticultural Society (RHS), meaning it can tolerate some cold.
It's often grown in woodland gardens or used as a groundcover, though it requires management to avoid invasiveness.
How to grow Chrysogonum virginianum in the garden
When it comes to planting and caring for Chrysogonum virginianum, you will want to choose a location that offers partial shade to full shade. While it can tolerate some sun, this plant thrives best when shielded from direct sunlight. Ideal soil conditions should be well-drained, humus-rich soil.
If you're planting from seeds, it's best to sow them in late summer to early fall, whereas if you're planting from purchased plants, it's better to do this in spring. Germination generally takes place in 14-28 days at temperatures around 70°F (21°C).
Propagation can be achieved by dividing established clumps in the spring, which is a straightforward process for even beginner gardeners.
Regular watering is essential for the Goldenstar, but be careful not to waterlog the soil. Annually applying a layer of compost can boost your plant's health and flowering potential.
This plant can be grown in pots and containers, making sure there is good drainage and partial shade. Although it's not typically grown as a houseplant due to its need for outdoor conditions, it's a common choice for patio containers and hanging baskets.
Notably, Chrysogonum virginianum is known to attract pollinators like bees and butterflies, enriching the local ecosystem, and it's also resistant to deer, making it a practical choice for gardens with wildlife.
However, watch out for slugs which may be attracted to this plant. With proper care and attention, the Chrysogonum virginianum will surely be a standout addition to your garden.
