Araucaria Columnaris vs Heterophylla
I’ve had the chance to grow Araucaria columnaris, and its striking, columnar shape and soft, feathery foliage always add a unique touch to my garden. I’ve found that its clean, vertical look really stands out compared to Heterophylla, which I also tried. Heterophylla’s more open and somewhat chaotic growth habit just didn’t blend as well with my other plants, even though it does have a more lush, almost tropical feel. Both are beautiful in their own right, but I personally prefer the disciplined appearance of Araucaria columnaris for a more formal garden setting.
Is Araucaria columnaris suitable for my garden?
Araucaria columnaris thrives in warm, temperate climates similar to its native environment. It prefers full sun exposure and thrives in moist, well-drained soil. While it can tolerate some drought, consistent moisture is ideal for optimal growth.
