Silene colorata: complete guide

Overview

Silene colorata, commonly known as Roman catchfly or carmine catchfly, is a beautiful Mediterranean plant from the Caryophyllaceae family (carnation family). This plant grows naturally around the Mediterranean Sea in countries such as Italy, Spain, Greece and North Africa.

The plant is known for its compact growth, delicate pink flowers and prolific flower production. It is an ideal choice for dry gardens, borders, rock gardens and flower boxes.

Appearance and Bloom

Silene colorata is a compact, low-growing plant that reaches twenty to forty centimeters tall. Growth is moderate, feeling like a dwarf plant.

The leaves are small, linear to lance-shaped, approximately two to four centimeters long. The leaves are green and have a fine texture. The plant forms a compact, dense bushy.

Flowers appear from April to June in northern Europe (longer in warmer areas). The flowers are small, approximately eight to ten millimeters wide, with five petals. The flowers are bright pink to carmine red, sometimes with white eye in the center. They grow in loose flower clusters at the tops of branches.

The fruits are small seed capsules with dozens of small seeds.
