New variety launches to trade in 2022 for Spring 2023 retail introduction

St. Paul, MN (January 7, 2022) – Bailey is excited to kick off 2022 by introducing Pop Star™ Hydrangea, the newest superstar in the Endless Summer® Hydrangeas collection, introduced by the company’s breeding arm, Bailey Innovations. Since 2004, Endless Summer® has revolutionized the bigleaf hydrangea marketplace, and Pop Star™ continues to deliver on and elevate the brand promise of season-long reblooming flower power, cold hardiness, and disease resistance.

“We have very high standards for every variety in the Endless Summer® collection,” shares Brand & Business Development Manager Layci Gragnani. “Pop Star™ exceeds every one of them.” Pop Star™ has gone through five years of robust testing and trials to ensure it meets the rigorous standards growers, retailers, and consumers have come to expect from Endless Summer® hydrangeas.

“Not only is Pop Star™ the most compact hydrangea we’ve developed, it’s also the strongest rebloomer we’ve ever trialed,” shares David Roberts, Bailey Innovations’ General Manager and Head Plant Breeder. “Pop Star™ represents the new gold standard by which we will evaluate all future introductions.”

A true breeding breakthrough, Pop Star™ sets that new standard with four key characteristics:

  • PROLIFIC REBLOOMER: In addition to the full coverage of early blooms, Pop Star™ is the quickest Hydrangea macrophylla in trial to rebloom, with new buds appearing just four weeks after a hard cutback to remove terminal buds.
  • GENETICALLY COMPACT: After years of trials across North America, Pop Star™ has maintained its small stature with short internodes that creates a tight, strong habit.
  • EASY TO GROW: The tight internodes and floriferous nature make Pop Star™ a fantastic production plant. With little to no PGRs needed and natural disease resistance, less touch points lead to a more profitable and easier plant to get retail ready. Additionally, the thick leaves add heat tolerance for production in warm climates and bud hardiness to protect Pop Star™ into Zone 4.
  • VERSATILE: Thanks to its compact size, flower power, and ease of use, Pop Star™ can be planted and make a big, colorful impact in any outdoor space. Whether it’s in the garden or a decorative container, Pop Star™ will be a superstar in the landscape.

Pop Star™ is available to Endless Summer® licensees in 2022 and will be available for industry-wide distribution and retail sales beginning January 1, 2023.


The Endless Summer® Collection is the world’s best-selling collection of garden hydrangeas. Introduced by Bailey Nurseries in 2004, Endless Summer® energized the demand for blooming shrubs and revolutionized the hydrangea market with the world’s first reblooming variety. All six varieties in the collection bloom on the previous seasons’ growth and the current season’s growth, providing an endless show of big, beautiful blooms all season long.
