Hibiscus plants vary widely in size depending on the species and cultivar:
- Most hibiscus shrubs range from about 2 feet tall for smaller or dwarf varieties up to 12 feet or more for large cultivars such as Hibiscus syriacus 'Blue Chiffon', which can reach 12 feet tall in a growing season
- Common perennial hibiscus species typically grow between 3 to 6 feet tall, but some can reach 8 feet or taller, especially in rich, well-drained soil
- Tropical hibiscus (Hibiscus rosa-sinensis) usually grow around 6 feet tall and wide, with some varieties like 'Butterball' reaching about 6 feet
- Hardy hibiscus species, such as Hibiscus moscheutos (Rose Mallow), can grow 6 to 10 feet tall and wide, often dying back in winter and regrowing each year
- Compact varieties like 'Honeymoon Red' stay smaller, around 2 to 3 feet tall, suitable for small gardens or containers
In summary, hibiscus plants can be as small as 2 feet or as large as 12 feet tall, with many common garden varieties growing between 3 and 8 feet tall and spreading similarly wide. The size depends largely on the species, cultivar, and growing conditions such as soil quality and climate
