Calling all green thumbs! Are you tired of the same old cactus plants in your collection? Looking for something unique that will make your neighbors envious? Introducing the Tricholobivia hybrid a stunning cactus that is a cross between the Trichocereus and Lobivia species.  The normally night-blooming Trichocereus now becomes a day-bloomer, and the thick, cylindrical stems bear some of the largest and most beautiful flowers in the cactus family, ranging in color from carmines, reds, salmon, and pure yellows to mammoth whites. Because of the pink trumpet-shaped flowers, it is also known as Tricholobivia pinkie.  This hybrid cactus typically has a globular or columnar growth habit, with ribs or tubercles running vertically along its green stem; covered in spines and can grow up to 1 foot tall and about 6 inches wide, making it a relatively compact cactus.  In terms of care, the Tricholobivia cactus prefers a well-drained cactus soil mix. It thrives in full sun to partial shade, so placing it near a sunny window or in a partially shaded outdoor area is ideal. When it comes to watering this trumpet flower cactus, it is important to allow the soil to dry out completely between waterings to prevent root rot. During the growing season, which is typically spring and summer, you can water the cactus more frequently, but still ensure the soil dries out between each watering.  The Tricholobivia hybrid, like other cacti, is adapted to arid environments and does not require high humidity. It can tolerate a wide range of temperatures in USDA zone 7-8, but it's best to keep it in a warm environment, ideally between 65°F and 85°F. Fertilizing with a balanced cactus fertilizer (NPK) once a year in the growing season can help promote healthy growth and vibrant blooms.  Overall, with proper care and attention to its specific needs, the Tricholobivia hybrid - trumpet flower cactus can thrive and bring joy to any cactus enthusiast.
