The Confederate rose, or Hibiscus mutabilis, can vary in height based on several factors, including climate, soil type, and regional conditions. On average, a Confederate rose can grow between 10 to 12 feet (3 to 3.7 meters) tall, with a width of 8 to 10 feet (2.4 to 3 meters). However, in optimal conditions, the plant can reach maximum heights of 12 to 15 feet (3.7 to 4.6 meters) with a woody trunk, especially in warmer zones like 9 and 10.
What is the Average Height of a Confederate Rose?
The average height of a Confederate rose typically ranges from 10 to 12 feet (3 to 3.7 meters) tall, with a width of 8 to 10 feet (2.4 to 3 meters). This is the most common size for the plant in various growing conditions.
What is the Maximum Height a Confederate Rose Can Reach?
In optimal conditions, without freezing, the Confederate rose can reach maximum heights of 12 to 15 feet (3.7 to 4.6 meters) with a woody trunk, especially in warmer zones like 9 and 10. This treelike form is more common in these warmer climates.
How Does Climate Affect the Height of a Confederate Rose?
In warmer climates, such as in zones 9 and 10, the Confederate rose can grow into a more treelike form, reaching the higher end of its height range. However, in cooler zones (e.g., USDA zones 7a and 7b), it tends to be more shrub-like and may not reach its full potential height due to winter dieback.
How Quickly Does a Confederate Rose Grow?
The plant grows rapidly, especially in the spring when soil temperatures warm up, and can grow 6-8 feet or more in a single season. It thrives in full sun and in soils with high organic matter, such as loam, clay, or sand with amendments. Well-drained but moist soil conditions also support healthier growth.
What is the Growth Timeline for a Confederate Rose?
The plant begins growing in the spring as soil temperatures warm up and can reach significant height by the end of summer. It blooms in the fall, typically from September through early winter. After a killing frost, the plant dies back to the ground but regrows from the roots in the spring. This cycle can affect its overall height each year, especially in regions with colder winters.
