Cultural Significance Around the World

Calibrachoa is primarily grown as an ornamental plant and is especially popular in the U.S. and Europe.

Recently, its popularity has also grown in Japan, where it’s appreciated for the ease with which its colorful flowers can be enjoyed in home gardens.

Calibrachoa has been heavily hybridized to enhance its vivid colors and rich blooms, leading to its nickname, “Million Bells.” It is also associated with symbols of abundance and happiness, making it a beloved addition to many gardens.

Historical Episodes

Calibrachoa is a relatively new addition to the world of horticulture, with its history dating back to the 1990s. Originally native to tropical areas like Brazil, Calibrachoa caught the attention of gardening enthusiasts due to its similarity to the petunia. Initially thought to belong to the same genus, advances in molecular genetics revealed it to be a distinct genus, now classified as Calibrachoa.

Since then, Calibrachoa has gained popularity in the gardening market for its tolerance to both moisture and cold. The creation of the “Million Bells” variety led to a surge in its popularity, and the plant’s resilient nature and low-maintenance requirements made it a common choice for home gardening. Many hybrid varieties have been developed since, allowing for a wide array of colors and shapes to be enjoyed worldwide.

Gardening Advice

Calibrachoa thrives in sunny spots, so it’s ideal to plant it where it can receive ample sunlight. Reduced sunlight may result in fewer blooms, so ensure the plant gets plenty of light. Well-drained soil that retains some moisture is best. Watering should be moderate; allow the topsoil to dry before giving it a thorough drink.

While Calibrachoa is drought-tolerant, it doesn’t like excessive moisture, so be careful to avoid overwatering. Monthly applications of a phosphorus-rich liquid fertilizer will improve blooming. Pruning back long stems can help maintain a neat shape and encourage new growth.

Conclusion

Calibrachoa, with its charming, colorful blooms, is perfect for brightening up a garden or balcony. By providing adequate sunlight and managing water drainage carefully, even novice gardeners can enjoy prolonged blooming periods. Try growing Calibrachoa in pots or hanging baskets to add a splash of color to your space!
