Purple Pillar Althea

Hibiscus syriacus 'Gandini Santiago'

Purple Pillar Althea is a space-saving standout with big impact. Its narrow, upright shape - 10 feet tall and only 4 feet wide - makes it ideal for framing doorways, planting in rows, or tucking into narrow beds where other plants just won’t fit. From spring through summer, it’s covered in semi-double, deep purple blooms with red centers, bringing lush, vibrant color to the landscape. Whether you're creating a privacy screen or just looking to add height and drama, Purple Pillar delivers.

  • Deciduous tree
  • Moderate growth rate
  • Columnar habit ideal for tight spaces or privacy
  • Long blooming season: spring through summer
  • Bold purple and red flowers
  • Very low to no seed production

Plant in full sun and well-drained soil. Hardy in USDA zones 5–9. Purple Pillar is a no-fuss, high-impact addition that brings both form and color without ever feeling bulky. It’s drought tolerant once established and beloved by pollinators.
