Frequently Asked Questions

How tall and wide does Purple Pillar® Rose of Sharon grow at maturity?

  • Purple Pillar® Rose of Sharon reaches 8-10 feet tall but stays just 2-3 feet wide at maturity. This columnar growth habit makes it perfect for tight spaces where you need height without width. Plant 3-4 feet apart for hedging or use singles as narrow accent plants.

What type of soil does Purple Pillar® Rose of Sharon prefer?

  • Purple Pillar® Rose of Sharon thrives in well-draining soil and tolerates a wide range of soil types, including clay and sandy conditions. This adaptable shrub isn't fussy about pH levels either. Plant in full sun for best flowering and shop at Nature Hills for healthy specimens.

How fast does Purple Pillar® Rose of Sharon grow per year?

  • Purple Pillar® Rose of Sharon grows at a moderate pace, typically adding 12-18 inches per year once established. This columnar shrub focuses its energy on upward growth rather than spreading outward. Expect to see strong vertical development during the growing season, with most height gained between spring and mid-summer.

Is Purple Pillar® Rose of Sharon deer resistant?

  • Rose of Sharon varieties like Purple Pillar® are generally deer resistant due to their tough, fibrous foliage that deer typically avoid. While no plant is 100% deer-proof, this shrub's natural characteristics make it an excellent choice for areas with deer pressure. Plant in full sun for best results and strongest deer resistance.

What plants pair well with Purple Pillar® Rose of Sharon in the landscape?

  • Purple Pillar pairs beautifully with low-growing perennials like coneflowers, black-eyed Susans, and ornamental grasses that won't compete for vertical space. Its narrow 2-3 foot width leaves plenty of room for companion plantings. Plant shorter pollinator favorites in front to create a layered garden that attracts butterflies and hummingbirds all season long.

Does Purple Pillar® Rose of Sharon require regular pruning?

  • Purple Pillar® Rose of Sharon requires minimal pruning due to its naturally columnar growth habit and low-maintenance nature. This variety produces few lateral branches and focuses its energy on upward growth. Prune lightly in late winter if needed to maintain shape or remove any dead wood.
