Purple Pillar® Rose of Sharon (Hibiscus syriacus 'Gandini Santiago') is a space-efficient, upright deciduous shrub that delivers unmatched vertical performance and color. Unlike standard hibiscus, Purple Pillar® grows as a tight column, reaching 10–16 feet tall while maintaining a narrow 4–5 foot spread. That upright structure opens up new design options for landscapes, especially in tight urban spaces, along property lines, or in large containers.¶It blooms from mid-summer into fall, with semi-double purple flowers stacked along each stem. As a reblooming, heat-tolerant, and drought-tolerant variety, it requires minimal maintenance while still offering months of visual impact. Ideal for privacy screening, vertical accents, and focal point planting, this award-winning shrub adds both form and function to retail inventories and commercial landscapes.
