Description

The Purple Althea (Hibiscus syriacus 'Purple') is a show-stopping deciduous shrub celebrated for its striking purple blooms that bring a dramatic flair to any garden. Also known as Rose of Sharon, this hardy shrub provides vibrant color and attracts pollinators, making it a favorite for gardeners seeking beauty and sustainability. With its long bloom season and adaptability, the Purple Althea adds elegance and charm to landscapes, hedges, or as a standalone focal point.

Unique Features:

  • Rich Purple Blooms: Large, bold purple flowers create a stunning visual impact, perfect for brightening up any garden.
  • Pollinator Magnet: Attracts hummingbirds, bees, and butterflies with its open, showy blossoms.
  • Long Bloom Season: Produces abundant flowers from midsummer to fall, offering months of vibrant color.
  • Adaptable Beauty: Thrives in a variety of soil types and is tolerant of heat, humidity, and drought once established.

Mature Size:

  • Height: 8–10 feet
  • Spread: 6–8 feet

USDA Hardiness Zones:

Care Instructions:

  • Light: Prefers full sun to part shade. For maximum blooms, plant in an area that receives at least 6 hours of direct sunlight daily.
  • Soil: Grows well in well-drained, fertile soil but adapts to various soil conditions, including sandy and clay soils.
  • Water: Water regularly during the first year to establish strong roots. Once established, it is moderately drought-tolerant but benefits from occasional deep watering during dry spells.
  • Pruning: Prune in early spring to maintain shape and encourage new growth. Flowers bloom on new wood, so annual pruning enhances flower production.
  • Fertilizer: Apply a slow-release balanced fertilizer in early spring to support healthy growth and blooming.
  • Pests/Disease: Resistant to most pests and diseases. Ensure proper airflow to prevent fungal issues, and treat aphids or Japanese beetles with organic insecticides if needed.

The Purple Althea is a must-have for gardeners looking to add a touch of bold elegance to their outdoor spaces. Whether planted as a hedge, a border, or a specimen shrub, this stunning plant brings a unique combination of beauty, resilience, and ease of care to any landscape.

How to Plant
STEP 1) First, decide on a planting location. Consider carefully what kind of sun, soil, and growing-space your tree or shrub will need.
STEP 2) Once you've located the perfect spot, the hole you are digging must be at least double the width and as deep as the root system you are planting.
STEP 3) Remove the plant from the pot and place the root ball in the hole. The top of the root system should be level with the ground. Before placing the tree or shrub in the hole, use your hands to gently break up the root system.
STEP 4) Once the plant is in place, backfill the hole with native soil and any leftover potting material.
STEP 5) Pack down the soil to eliminate any air pockets.
STEP 6) When finished, water thoroughly.
Care Guide

For the first growing-season, water on a weekly schedule. Once the plant is established, water only as needed. Prune twice a year, once in the winter and once in mid-summer.
