Firecracker plant, also known as Cuphea ignea, is a popular plant among gardeners, thanks to its bright red-orange tubular flowers that attract hummingbirds and butterflies. It is a perennial plant that grows well in warm climates and can reach impressive heights. In this article, we will explore how tall the firecracker plant can grow and what factors affect its growth.

Factors Affecting the Height of Firecracker Plant

Several factors can affect the height of firecracker plants, including:

Climate

Firecracker plants thrive in warm climates and require plenty of sunlight to grow. They can grow up to 3 feet tall in areas with warm temperatures and full sun exposure. However, in cooler climates or areas with less sunlight, firecracker plants may not grow as tall.

Soil Quality

The soil quality also plays a crucial role in the growth of firecracker plants. They prefer well-draining soil that is rich in organic matter. If the soil is too compacted or lacks nutrients, the plants may not grow as tall.

Watering

Firecracker plants require regular watering to ensure healthy growth. They prefer moist soil but do not like to be overwatered. Overwatering can lead to root rot, which can stunt their growth.

Fertilizer

Fertilizer is essential for promoting healthy growth in firecracker plants. They benefit from a balanced fertilizer that is rich in nitrogen, phosphorus, and potassium. However, too much fertilizer can cause excessive foliage growth at the expense of flower production.

How Tall Can Firecracker Plants Grow?

Under ideal growing conditions, firecracker plants can reach heights of up to 3 feet with a spread of 2 feet. However, their height can vary depending on the growing conditions and cultivar.

Some cultivars of firecracker plants, such as the ‘David Verity’ cultivar, are known for their tall growth and can reach heights of up to 4 feet. In contrast, dwarf cultivars such as the ‘Tiny Mice’ cultivar only grow up to 12 inches tall.
