Cosmos bipinnatus Antiquity | Early Flowering Cosmos | Compact Cosmos Seeds

Cosmos bipinnatus ‘Antiquity’ is a charming and unique cosmos variety valued for its early flowering and compact growth habit. The elegant 5 cm semi-double flowers open in a deep burgundy red and gradually fade to beautiful antique bronze-salmon tones, creating a soft vintage colour effect in the garden.

This variety blooms earlier than most cosmos and produces an abundance of flowers throughout the season. Its compact plants reaching around 45 cm make it perfect for flower beds, borders, and container planting.

‘Antiquity’ is an excellent choice for gardeners who want the classic charm of cosmos but in a shorter, tidy plant with unusual colour transitions. It also performs well in pots and patio containers.

Cosmos are well known for being easy to grow, resilient, and long flowering, making them a favourite in cottage gardens and cutting gardens.
