Colletia: The Intriguing Crucifixion Thorn Plant
Introduction
Are you searching for a plant that’s both unusual and eye-catching? Look no further than the Colletia plant, commonly known as the Crucifixion Thorn Plant. Native to South America, this unique specimen boasts a captivating mix of danger and whimsy.
What is a Colletia Plant?
Colletia is a shrub that can grow up to 8 feet tall and wide. Its most striking feature is its flat, triangular stems that resemble anchors or jet plane propellers. These stems are photosynthetic, meaning they can produce food for the plant through sunlight. From these stems, almond-scented, creamy ivory flowers bloom from summer until fall.
Growing Colletia Plants
Due to their rarity, Colletia plants are typically only found in botanical gardens. However, if you’re lucky enough to find one, here’s how to care for it:
- Sunlight: Colletia plants thrive in full sun.
- Soil: They prefer well-drained, gritty soil.
- Water: Once established, they require very little water.
- Winter Hardiness: Colletia plants are winter hardy down to 20 degrees Fahrenheit (-6 C.) with proper protection.
Propagation
Propagating Colletia plants is best done through semi hardwood to hardwood cuttings. Take non-flowering early side shoots in early fall and pot them up in a cold frame to over winter. Rooting can be slow, up to 2 years, so be patient and keep the cutting lightly moist.
