Growing Catchfly Flowers as Houseplants or in Your Home Garden

Catchfly flowers are easy to grow and will thrive in even poor soils. They look great in English-style cottage gardens. You can grow them in flowerpots on your patio or deck. Also, try growing catchfly carnivorous plants indoors as a houseplant, too.  

Native to Europe and Africa, some consider this a carnivorous, plant as it traps flies and insects on its sticky calyses. Actually, the plants are not true meat-eaters. Once an insect is captured, it does not consume the insect, like most true carnivorous plants.

The Catchfly plant is a perennial plant. However, most gardeners grow it outdoors as an annual. It produces vivid colors of pink, magenta, red, and white. Blooms are 3/4 to 1 inch across and have no floral scent. Its stems and leaves are covered with fine white hairs.

Catchfly flowers are at home in English cottage gardens, as a country wildflower. Use them as borders, and in containers.

Did You Know? These plants were used in African rituals to influence dreams.

The plants grow best in slightly alkaline soil. They do well in average to poor soils and even rocky soils. However, they respond well to better soils. And, it is important that the soil is well-draining Soggy soils can kill the plant.

Use a general-purpose fertilizer once or twice a season for best performance.
