There Globose craspediaknown botanically as Pycnosorus globosusis one perennial herbaceous plant That captures attention to its unmistakable yellow spherical inflorescences. Originally from Australia and New Zealand, this species has spread throughout Europe, including Italy, conquering the gardens with its curious form that recalls a golf ball.
The name derives from the Greek “Kráspedon” which means fringe, reference to the particular structure of its flowers. The plant is also known with the curious name of “Bacchetta flower” or “Billy Button” and in the language of flowers symbolizes the luck and joy of living.
Characteristics of the plant
The globular craspedia is robust bushes that reach 60-65 cm both in height and in width. The leaves are lanceolate and linear, green-argento in color, covered with a slight hair that gives the plant a particular appearance. The radical apparatus is very developed and resistant.
Flowering takes place from June to September, with possible extensions up to the first colds. In particularly mild climates, the plant can flourish almost all year round. The flowers consist of globular inflorescences of 2-3 cm in diameter, composed of numerous small yellow flowers called Flosculi. These flowers are highly appreciated by butterflies and bees and have an exceptional duration, persisting on the plant for at least 15 days.
How to cultivate globose craspedia in the garden
The globular craspedia adapts perfectly to the Mediterranean gardens and rocky flower beds. For optimal growth requires at least 6 hours of sunshine per day and well -drained soil. It is important to maintain a distance of 30 cm between the plants during planting.
The plant tolerates temperatures up to -12 ° C, but in areas with particularly rigid winters it is advisable to protect the radical apparatus with a mulch. During the summer he resists well in the intense heat and drought periods.
How to cultivate the globes in pots
On the terrace or balcony, the globous craspedia behaves very well if cultivated in adequate containers. It is essential to guarantee a sunny position, perhaps close to a well -exposed window. For multiple plants in the same pot, keep at least 20 cm away between the specimens.
During the flowering period it is useful to provide liquid fertilizer every 15 days to support the production of the characteristic yellow flowers.
How to irrigate and what land to use
Despite its drought resistance, the globular craspedia benefits from regular irrigations that guarantee more abundant blooms. In the garden, natural rains are often satisfied, while in the pot it needs more frequent watering, especially in the summer months.
The ideal soil is soft, rich in organic substance and well drained. A mixture of universal soil with the addition of peat and sand is perfect for this plant.
How to treat it season per season
During the winter the globular craspedia enters into vegetative rest. In the colder areas, the aerial part can completely dry out, but this must not worry because the roots remain vital and the plant will resume vegetable with the arrival of spring.
For pots in pots in the most rigid regions, it is advisable to move the containers to the cold greenhouse or to repaired but bright places when the temperatures drop around 5 ° C.
How to propagate globosa craspedia
Multiplication takes place mainly by seed or division of the tufts. Sowing is carried out in spring between March and May, using specific seedbeds and keeping the substrate always humid until germination. The division of the CESPI is practiced in early spring, separating the mother plant in several portions equipped with roots.
Resistance and maintenance
One of the most appreciated characteristics of the globular craspedia is its rusticity. It is rarely attacked by parasites, occasionally it can be subject to aphids. The only significant risk is represented by radical rot in case of water stagnation.
Maintenance is minimal: just remove dry leaves and dried flowers to keep the plant in order. There are no particular pruning or excessive fertilizations, if not the addition of mature compost at the time of the system.
Common problems in the treatment of globular craspedia
Yellowing of the leaves
The yellowing of the leaves can derive from various factors, such as excessive irrigation, a lack of nutrients or an excessive exposure to the sun. To deal with this problem, check the irrigation methods, ensuring that the soil is well drained. In addition, check that the plant is not exposed to too much direct light, especially during the hottest hours of the day.
Rotten rot
The rot of the roots is generally caused by too humid or too frequent irrigation soil. To avoid this, it is essential to choose a well -drained substrate and allow the soil to dry between one wetting and another. During periods of inactivity of the plant, you further reduce the frequency of irrigation.
Flowers dried or fallen prematurely
This problem may be due to inadequate irrigation, too high temperatures or exposure to air currents. It is important to provide the right amount of water and protect the plant from thermal changes and too strong fans. Place it in an area where it can enjoy a stable temperature, avoiding heat or cold strokes.
Weak or slowed growth
Slowly or weak growth can be the result of a lack of nutrients in the ground. To stimulate healthy growth, it applies a low -concentration balanced fertilizer, which will provide the necessary nutrients. In addition, make sure that the plant receives an adequate amount of sunlight and that the soil is of good quality.
Globose craspedia is safe for pets
Globosa craspedia does not have risks of toxicity for dogs and cats. Its flowers and leaves do not contain harmful or irritating known substances, but it is always good practice to observe animals when they come into contact with new or little -known plants, since reactions can vary from one animal to another.
