Product Details

Purple Pillar Althea Tree Form

Hibiscus syriacus 'Gandini Santiago'

Purple Pillar Althea Tree Form is prized for its naturally slender silhouette and abundant deep purple flowers that bloom through the summer months. Trained into a clean single-trunk form, it delivers height and color without taking up much horizontal space. The bold purple blooms contrast beautifully against dark green foliage, creating a striking vertical accent along walkways, fences, or entryways. At maturity, this althea reaches 10 to 16 feet tall and spreads just 4 to 6 feet wide, making it an excellent solution for narrow beds or modern landscape designs where space is limited.

  • Deciduous flowering tree form
  • Moderate growth rate with a tall, columnar habit
  • Rich purple summer blooms
  • Perfect for narrow spaces, accents, or vertical interest
  • Adds structure and long-lasting seasonal color

Purple Pillar Althea Tree Form performs best in full sun and well-drained soil. Hardy in USDA zones 5 through 9, it adapts well to Texas conditions and brings dependable height, color, and architectural appeal to the landscape.
