Flamethrower plant, also known as the Red Hot Poker plant, is a popular choice for gardeners looking to add a touch of color and drama to their gardens. They are native to South Africa and can grow up to 5 feet tall with striking spikes of red, orange, and yellow flowers. One question that many gardeners ask is how quickly these plants grow. In this article, we will explore the growth rate of flamethrower plant and provide some tips on how to care for them.

Growth Rate of Flamethrower Plant

Flamethrower plants are relatively slow-growing and can take up to three years to reach their full height. However, this growth rate can depend on various factors such as soil, climate, and care. In general, flamethrower plants grow best in full sun and well-draining soil. They can also tolerate some drought but do require regular watering during the growing season.

During the first year of growth, flamethrower plants will typically produce only a few leaves and may not flower. In the second year, they will start to develop flower spikes that can reach up to 4 feet tall. By the third year, they will have reached their full height and will produce multiple flower spikes.

Caring for Flamethrower Plant

To ensure that your flamethrower plant grows healthy and strong, here are some care tips to keep in mind:


Flamethrower plants prefer well-draining soil that is rich in organic matter. They do not like wet feet and can suffer from root rot if the soil is too heavy. Adding compost or peat moss to the soil can help improve drainage and fertility.


Although flamethrower plants can tolerate some drought, they do require regular watering during the growing season. Water deeply once a week, or more often during hot weather, to ensure that the soil is moist but not waterlogged.


Flamethrower plants benefit from regular fertilization during the growing season. Use a balanced fertilizer every two weeks or a slow-release fertilizer once a month to provide essential nutrients for growth and flowering.


To promote healthy growth and flowering, prune back any dead or damaged leaves and flower spikes as soon as possible. This will encourage new growth and prevent disease from spreading.
