Opus™ III Early Bronze Antirrhinum

Opus III Early Bronze is an orange-bronze snapdragon bred by Syngenta for professional cut-flower production. The Americas product page lists garden height at 24–30 inches and width at 14–16 inches; Syngenta’s APAC page gives a taller regional garden-height estimate of 100–110 cm and width of 35–40 cm, so the two height ranges are reported separately. ## Flowers and harvest The [Syngenta Americas record for item 70018059](https://www.syngentaflowers.com/americas/product/flower/70018059) identifies Opus III Early Bronze and gives the 24–30-inch garden range. The [Syngenta APAC record for the same item](https://www.syngentaflowers.com/apac/product/flower/70018059) lists 100–110 cm garden height and 35–40 cm width. Syngenta’s [Opus catalog](https://www.center-flowers.com/web/content/files/SYNGENTA-CATALOG.pdf) includes Early Bronze among its F1 cut-flower selections. Regional dimensions are kept distinct rather than combined into a single range. ## Siting Provide sun and well-drained soil. The [RHS Antirrhinum majus profile](https://www.rhs.org.uk/plants/69565/antirrhinum-majus/details) offers species-level siting guidance; commercial crop timing also responds to light and temperature. ## Maintenance Harvest cut stems as lower florets open and keep them upright during handling. In garden settings, remove spent flower spikes; RHS notes that deadheading can prolong snapdragon flowering.
