Summary
commonly known as the golden-flowered century plant, it has gorgeous yellow gold flowers that appear when it matures. It is a magnificent succulent plant with golden yellow flowers that may grow up to 7 meters tall. Large, fleshy, sword-shaped leaves form a tight, almost spherical rosette. The gray-green leaves are indented along their center, creating a canal. The sides of the leaves and the tip feature prominent spines that can injure on contact, so handle with care. After flowering and producing seeds, the plant eventually dies.
1. Light and Location
This plant requires a bright, sunny location. Full sun is best, but it can also be grown in light shade. It does well in direct sunlight to slight shade. A window with a south or southeast direction is ideal. Plant Golden Flowered Century Plants in an area that receives at least six to eight hours of direct sunshine each day.
2. Watering
Water this plant in the spring when the top inch of soil is completely dry. Keep the soil from drying out completely. Water relatively little during the winter and fall, when growth is slowed.
3. Temperature
The optimum temperature is between 55 to 75 degrees Fahrenheit. To ensure that Agave chrysantha stays healthy and happy, it is important to ensure that it gets the right temperature and humidity.
4. Humidity
The ideal relative humidity is between 40 to 60 percent. This plant is extraordinarily heat-tolerant and can survive harsh desert conditions quite easily.
5. Fertilization
If you want to keep your Agave chrysantha in good shape, fertilize it once or twice a year. Choose a slow-release fertilizer that’s designed for cactus and succulents. A balanced fertilizer will provide nitrogen, phosphate, and potassium.
6. Propagation
Golden-Flowered Century Plant can be Propagated through its offsets or what are called pups, which usually develop around the mother plant’s base. Propagation using offsets will not only produce new plants but also improve the mother plant's appearance as a single specimen. Simply place a knife between the offset and the parent plant, cut through the roots connecting them, and leave at least one inch of the stem behind to begin the process.
7. Potting and Repotting
Potting and Repotting Agave chrysantha should be done in spring when temperatures are somewhat stable. This plant needs a container that has drainage holes and balanced soil for its roots. Use clay or terracotta pots since they allow the soil to drain better. The soil should be well-draining and aerated. A good option is a cactus mix amended with perlite, pumice, or vermiculite. Choose a sunny spot for your Agave and make sure there’s enough room for it to grow.
8. Toxicity and Common Pests
The sap of the Agave chrysantha is mildly toxic and can cause skin irritation, dermatitis, and even an allergic reaction in sensitive individuals. The Agave chrysantha is susceptible to different pests including Scale insects, Agave snout weevil, slugs, and snails.
9. Please Note and Avoid
Over-watering
Placing Under Harsh Sunlight
Using Poorly Drained Potting Mediums
Fertilizing During Dormancy
