Cool Crimson Snapdragon

Cool Crimson snapdragon (Antirrhinum majus ‘Cool Crimson’) produces upright spikes of crimson flowers on strong stems. PanAmerican Seed lists this Cool series selection for cool-season greenhouse and high-tunnel production, with flowering reported in early spring, autumn and winter and stems about 39–60 inches long ([Cool Crimson](https://www.panamseed.com/Products/057803347001353/snapdragon-cool-crimson/); [PanAmerican Seed cut flower catalog](https://www.panamseed.com/PdfAssets/pdfpage.aspx?pdfid=250)). ## Garden Use and Growing Conditions The tall stems suit cutting and display in borders. PanAmerican describes the series as winter-flowering and adapted to cool production conditions; its length and flowering window refer to commercial production, so outdoor timing depends on local climate and planting date. For garden culture, snapdragons grow in full sun and well-drained soil; Illinois Extension describes them as cool-season flowers commonly planted in spring or fall ([Illinois Extension](https://extension.illinois.edu/flowers/snapdragon)). ## Maintenance Remove spent flower spikes to encourage additional growth and keep the planting tidy. Provide support if tall stems lean, and avoid persistently wet soil. Illinois Extension recommends deadheading and notes that tall snapdragons may need staking; these are species-level care guidelines rather than cultivar-specific trials.
