It is renowned for its large, heart-shaped leaves and beautiful, fragrant flowers that bloom in spring. The tree can grow rapidly, making it an excellent choice for providing quick shade or enhancing landscape beauty.

Paulownia Tomentosa vs Elongata

I’ve found Paulownia Tomentosa, with its faster growth and vibrant, large leaves, really impressive for quick shade, but Paulownia Elongata‘s more elongated leaves and slower growth gave me a unique and more elegant touch to my garden, making it a bit less common but equally beautiful in its own way.

How to Grow Paulownia Tomentosa?
