The Story

Plant Bio

Rhododendrons are a large genus of woody plants, mostly shrubs, prized for their showy, often colorful, spring flowers. They are typically acid-loving plants with shallow root systems. 'Roblezd', or Autumn Bonfire®, is a compact, reblooming Encore® Azalea known for its profuse, true-red, semi-double flowers. It blooms heavily in spring, summer, and fall.

Bloom Period:

EarlyLate

Uses & Benefits:

Delivers a powerful punch of true red color throughout the growing season. Its compact, mounding habit makes it ideal for mass plantings, borders, and containers, providing non-stop visual appeal.

Functions as a low-maintenance, evergreen, flowering hedge that rarely needs pruning to maintain its neat shape. Excellent for adding structure and color to small garden spaces.

The extended bloom time provides a consistent nectar source for hummingbirds and bees from spring through fall, supporting a healthy pollinator population in the garden.
