In the garden
Antirrhinum majus 'Sumanthir 03' belongs to the genus Antirrhinum in the Plantaginaceae and is offered specifically as a bedding and cut-flower cultivar. Its deciduous foliage and concentrated flowering period make it straightforward to plan for a summer display and cutting schedule. Position it in full sun on a south-facing, sheltered border and choose a neutral loam that does not remain waterlogged; good drainage is important. The H3 rating means it is borderline hardy in UK conditions, so gardeners in colder or exposed sites commonly lift plants for winter, provide frost protection or treat it as a tender annual to avoid winter loss. Use groups in mixed bedding schemes or dedicate a short run for cutting; the season of interest runs June to September. Because it is valued for cut flowers, plant where stems are easily reached for harvesting and avoid overcrowding so airflow reduces the risk of moisture-related issues. Antirrhinum majus 'Sumanthir 03' performs best when sited to receive strong sun and shelter from prevailing winds, giving reliable summer blooms for borders and vases.
