Rhododendron x hybrida 'Conlep'

The Story

Plant Bio

Rhododendrons are broadleaf evergreen or deciduous shrubs in the heath family that prefer acidic, highly organic soils with sharp drainage. Their shallow root systems bear open funnel-shaped blooms held in terminal clusters above smooth, leathery leaves.

'Conlep' is a multi-stemmed evergreen azalea that forms an upright, rounded shrub four to six feet tall with narrow glossy foliage. It produces three-inch purple and white striped flowers in multiple flushes across spring, summer, and fall.

Uses & Benefits:

Ornamental UsesOffers multi-season reblooming interest with unique, variable purple and white striped flower patterns.
Practical UsesFunctions as a dense, evergreen structure plant for year-round garden framing.
Ecological BenefitsProvides nectar for hummingbirds, butterflies, and native pollinators over an extended blooming window.
Garden hybrid

Bred from more than one wild species, so it has no species page of its own.

Planting

How to Grow

  1. Select a site receiving 4 to 6 hours of morning sunlight with afternoon shade protection.
  2. Amend sandy or dense soils with rich organic compost to lower pH and retain moisture without waterlogging.
  3. Dig a shallow hole twice as wide as the root ball and plant so the crown sits slightly raised above the surrounding grade.
  4. Apply a 2 to 3 inch layer of pine bark or pine needle mulch over the root zone, keeping it away from direct stem contact.
  5. Water thoroughly at planting and establish a consistent irrigation schedule to keep shallow roots evenly moist.

Pro Tip

Set the top of the root ball one to two inches above soil level when planting to maintain optimal aeration and prevent Phytophthora root rot.

Care Guide

Do

  • Maintain consistent soil moisture throughout the hot summer months.
  • Use an acid-formulated fertilizer twice per year in spring and mid-summer.
  • Protect root structures with a thick organic bark mulch.

Don't

  • Do not plant in alkaline or heavy, poorly drained clay soil.
  • Do not cultivate the soil around the base, as this severe root damage.
  • Do not prune late in the summer, which removes emerging buds for the following season.
