More About Orange Star Plants
The orange star plant, also known as the star of Bethlehem or the sun star plant, is a true eye-catcher. With its bright orange flowers delicately perched on tall, thin stems among lime-green leaves, it creates a spectacular bouquet. The fascinating botanical name for this plant is Ornithogalum dubium, and it grows up to 20 inches tall with lanceolate foliage. Native to South Africa, the orange star plant belongs to the Asparagaceae family. While the most common variety displays bright orange flowers, some varieties showcase beautiful white blooms.
Orange Star Plant Care Tips
Where to Plant Orange Star Plant
To ensure the optimal growth of your orange star flowers, find a sunny spot to plant them. These plants thrive in full sun, so make sure they receive at least six hours of direct sunlight daily. In hot climates, providing a little afternoon shade can benefit the plants. Avoid planting them in full shade, as they will not thrive in such conditions.
Orange Star Plant Soil Needs
The best soil for orange star plants is loamy and well-draining. It should be fertile enough to retain water without becoming waterlogged. When landscaping or growing them in pots, ensure that adequate drainage is in place. For indoor plants, adding some sphagnum peat moss mixed with perlite to your potting soil can help improve drainage.
Watering Orange Star Plants
Keep a close eye on the moisture level of the soil. Water your orange star plants when the top layer of soil feels dry. During the growing season of spring and summer, watering once a week is typically sufficient. However, on very hot summer days, you may need to water them twice a week. For overwintering bulbs in the ground, it is recommended to keep the soil moist. When watering potted orange star plants, allow the water to drain through the holes and remove any excess water from the saucer. Overwatering can result in mushy stems and wilted flowers.
Temperature and Humidity For Orange Star Flower
Orange star plants thrive in temperatures ranging from 60°F to 80°F (16° – 27°C). They are not cold-hardy plants and do not survive freezing climates. In warmer regions, providing some afternoon shade can be beneficial. For colder zones, you can overwinter the bulbs indoors or in pots in a cool and dry place. Ensure that the plants are kept away from AC units, heaters, and vents, as they can be sensitive to temperature fluctuations. Proper air circulation is essential for the health of the foliage and to prevent humidity-related issues.
Winter Care For Sun Star Plant
During the colder months, you can protect your orange star bulbs from frost by digging them up before the first frost date. Remove the foliage and store the bulbs in a dark and cool place. When spring arrives, you can transplant them back into your garden. Alternatively, if you live in a milder climate, you can leave the bulbs in the ground and cover them with mulch for added protection.
Fertilizing Orange Star
To enhance flower development, your orange star plants can benefit from a high-potassium fertilizer. Opt for a fertilizer specifically formulated for flowering plants to replenish the necessary nutrients. Alternatively, you can use organic fertilizers or incorporate compost into the soil to promote growth. For potted plants, diluted houseplant feed once a month during spring and summer is recommended. Refrain from fertilizing and watering during the winter months.
Repotting and Pruning Orange Star Plants
For indoor plants, repotting your orange star flowers once a year in late summer can help them thrive. Choose a larger pot to allow more room for the bulbs to grow. While repotting, you can remove offsets and refresh the soil. Pruning is minimal, and you only need to remove any dead or yellowing leaves. Cutting the leaves down to the ground can improve the appearance of your orange star flowers. After the bright orange flowers fade, the dark green leaves will die and become dormant.
Propagating Orange Star Flower
The most effective way to propagate your orange star plants is by dividing the bulbs or removing offsets from mature plants in the fall. Dig up the bulbs and separate the smaller bulbs attached to the mother plant using a sterilized sharp knife. Plant the offsets in pots or back into your flower garden. Dividing the bulbs can be done approximately every six years. Alternatively, you can plant the bulbs in a cool area with moist soil during winter for new growth to appear in spring. Another option is collecting the orange star plant seed pods after flowering. The pods should be removed before they drop to the ground and left to dry for a week. Store the tiny seeds in a dry and cool environment. When starting the seeds in moist soil mixed with peat moss, perlite, and fine bark, keep them in a shady spot and ensure they remain moist. It may take up to four years for the plant to bloom.
Ornithogalum Varieties
While the orange star plant is an exceptional species, there are several other Ornithogalum varieties that can be a charming addition to your flower garden.
Ornithogalum arabicum
Also known as the lesser cape-lily, Arab’s eye, or Arabian starflower, this variety features white flowers and is native to South Africa.
Ornithogalum maculatum
Native to Southern Africa, the snake flower showcases long stems and orange flowers.
Ornithogalum pyrenaicum
Also known as the Prussian asparagus or the wild asparagus, this variety offers the added bonus of young flower shoots that can be enjoyed as a vegetable. It is native to the Pyrenees.
Common Pest and Disease Problems
While orange star plants are generally hardy, they can be susceptible to pests and diseases. Thrips are insects that may bother these plants, but they can be easily dealt with by hosing them down with water. If you are growing your plants indoors, isolating them and using a neem oil spray can help control pests. Root rot is a common disease that can occur due to overwatering. To prevent this, ensure that the top layer of soil is dry before watering.
By following these care tips and providing your orange star plants with the right conditions, you can enjoy their vibrant beauty and make your garden truly captivating. Whether you choose to grow them in your flower beds or in pots, these plants are sure to bring a touch of sunshine to your outdoor space.
