Description
Colourful Flower Clouds from Mexico
The Cosmos, also known as Mexican aster or Cosmea, originates from the southwestern regions of North and Central America – from Arizona through Mexico to Costa Rica. Today, it is among the most popular annual summer flowers in Europe, and for good reason: its fragrant blooms in white, pink, and purple have a light, playful charm that transforms any border into a vibrant cloud of colour.
Cosmos is easy to care for, drought-tolerant, and thrives even in relatively poor soils. It prefers a sunny position and is a true long-flowering plant: from July until the first frost, it continues to produce an abundance of bowl-shaped blooms. Its fine, feathery foliage adds a delicate, airy texture. It also makes an excellent cut flower.
Although the plant is not frost-hardy, it can establish itself in the garden through self-seeding under suitable conditions. It is especially effective in naturalistic gardens, perennial borders, or wildflower strips – and can even be successfully grown in rock gardens.
