Cultivation Guidelines
Prefers a sunny position but tolerates partial shade – at least 6 hours of sunlight daily is recommended for best flowering. Enjoys cool climates and is highly cold-hardy, but does not tolerate extreme heat – provide good air circulation and some afternoon shade in hot summer conditions. Water following the 'see dry, see wet' principle – keep soil evenly moist but never waterlogged, as excessive moisture can cause root rot. Plant in well-drained, aerated sandy or loamy soil. Apply a light dose of balanced fertiliser during the growing season and deadhead spent flowers after blooming to encourage a second flush of flowers.
