Native Rockery Plants That Thrive in South East Queensland

Introduction

In the verdant landscapes of South East Queensland (SEQ), native rockery plants offer a harmonious blend of resilience and beauty. These indigenous species, adapted to the region's unique conditions, provide gardeners with the opportunity to create stunning, low-maintenance rock gardens that celebrate local flora.

Understanding SEQ's Climate and Soil

SEQ's subtropical climate is characterized by hot, humid summers and mild, drier winters. This climatic pattern influences soil moisture levels and temperature fluctuations, impacting plant growth.
