Monaco Yellow Snapdragon

Monaco Yellow is a yellow-flowered snapdragon in PanAmerican Seed’s Monaco F1 series, selected for high-quality spikes through seasonal transitions. PanAmerican lists a 32–60-inch product height and describes Monaco as a commercial cut-flower crop; these production measurements do not establish mature garden height. ## Flowers and harvest Use Monaco Yellow for cut stems and bright vertical accents in arrangements. The [PanAmerican Monaco catalog](https://catalog.panamseed.com/view/445948364/190/) lists Yellow among series selections and describes greenhouse or high-tunnel production, transition-season use, and harvest when five or six florets open. PanAmerican’s [breeder guide](https://www.panamseed.com/PdfAssets/pdfpage.aspx?pdfid=16) describes Yellow’s role between other snapdragon groups in spring and autumn. ## Siting Grow in sun and well-drained soil. PanAmerican describes Monaco as performing well in moderate temperatures with little day-length fluctuation. The [RHS snapdragon profile](https://www.rhs.org.uk/plants/69565/antirrhinum-majus/details) provides general species guidance. ## Maintenance Remove spent spikes from garden-grown plants to prolong flowering, following RHS snapdragon guidance. For harvested stems, keep them vertical during handling and storage to prevent curling.
