Plant Attributes

The Purple Pillar® Rose of Sharon (Hibiscus syriacus) is known for its unique columnar or narrow growth habit, which is a distinctive feature setting it apart from other varieties.

Besides its aesthetic appeal, the Purple Pillar® is a magnet for pollinators like bees, butterflies, and hummingbirds, promoting biodiversity in the garden.

Planting & Care

Planting Instructions:

  • Location: Choose a location that receives full sun, which means the area should get at least 6+ hours of sunlight per day.
  • Soil Preparation: Ensure the soil is well-draining. You may amend the soil with compost or well-rotted manure to improve its fertility and drainage.
  • Planting Depth and Spacing: Plant at the same level it was in the container. For individual plants, adhere to a spacing of 48 to 60 inches to allow for growth and air circulation.
  • Watering: Water thoroughly after planting. While the Purple Pillar® Rose of Sharon is drought-tolerant once established, it will benefit from consistent watering during the first growing season to establish a deep, extensive root system.

Care Instructions:

  • Watering: Once established, reduce the frequency of watering. However, during prolonged dry spells, additional watering may be necessary.
  • Fertilizing: Apply a balanced slow-release fertilizer in early spring to promote healthy growth and flowering.
  • Mulching: Apply a layer of organic mulch around the base of the plant to help retain soil moisture and suppress weeds.
  • Pruning: Little to no pruning is required due to its narrow habit. If desired, any pruning should be done in early spring to maintain shape or remove any wild branches or dead wood.
  • Winter Care: While specific winter care instructions were not provided, it's advised to avoid planting in areas where snow may fall off roofs. In colder zones, applying mulch can help protect the root system during winter.
  • Pest and Disease Management: Monitor the plant for common pests and diseases. If any issues arise, treat with appropriate organic or chemical controls, following the manufacturer's instructions.
  • Drainage: Ensure the area has good drainage to prevent waterlogging, which can lead to root rot.

Additional Tips:

  • Pollinator Attraction: The Purple Pillar® Rose of Sharon attracts bees, butterflies, and hummingbirds, promoting a lively and biodiverse garden.
  • Deer Resistance: The plant is noted for its deer resistance, which is a bonus in areas where deer browsing is a concern.
