Boasting a unique upright stature, the 'Purple Pillar®' stands tall, reaching heights of up to 15 feet while maintaining a slender, columnar form. Its dense foliage of deep green leaves provides a lush backdrop for the star of the show—lavish, purple blossoms. In mid to late summer, clusters of large, vibrant purple flowers adorn the branches, creating a spectacle of color and charm. These blossoms attract pollinators such as butterflies and hummingbirds, enhancing the biodiversity of your garden.
The 'Purple Pillar®' is also a low-maintenance and adaptable plant. This hardy shrub is disease-resistant, cold-hardy, and drought-tolerant once established, making it a resilient choice for various climates. Plus, you can expect your 'Purple Pillar®' to produce heavy blooms throughout a long blooming period of summer through fall.
Ideal for use as a focal point in landscapes, the 'Purple Pillar®' can also be incorporated into narrow hedges, screens, formal gardens, entryways, and decorative containers. Its vertical growth habit makes it a space-saving option for urban gardens or smaller areas where traditional shrubs may not fit.

Love it!
I planted it as soon as I got it - which had no leaves of course. It immediately started growing beautiful leaves. It’s a happy plant and so am I!
Beautiful 💜
Plants arrived in very good shape in spite of the heat wave. They have been planted and are already blooming. They look healthy.
