Opus III Early Bronze is a vibrant, compact snapdragon bred for speed and sophistication. This F1 hybrid produces striking orange-bronze blooms on plants that reach flowering in just 105-115 days, making it one of the earliest snapdragons to deliver color. Hardy from zones 2-11, it thrives in partial shade with moderate water and neutral soil, reaching a tidy, branched form when pinched. Both the flowers and foliage are edible, opening unexpected culinary possibilities beyond the cutting garden.

Vibrant orange-bronze flowers emerge reliably fast on compact plants that don't sprawl or demand fussing. The color is warm and sophisticated, far richer than typical snapdragon reds. Light is required for germination, so seed flats should sit uncovered or under fine vermiculite rather than buried in soil, a detail that separates success from leggy seedlings. Whether you're breeding dense, branching plants or letting them grow naturally, pinching early in the season shapes them into fuller performers.
Opus III Early Bronze excels as a cut flower for summer bouquets, where its orange-bronze spikes add warmth and height to mixed arrangements. The flowers are also edible and can be used as garnish or in salads, though they're grown primarily for their ornamental display rather than culinary application.

Surface-sow seeds 8-10 weeks before your transplant date into 128-cell flats or preferred seedling containers. Light is required for germination, so cover seeds just enough with a fine layer of vermiculite to hold them in place and maintain moisture without blocking light. Bottom water or mist lightly to avoid displacing seeds. Maintain temperatures between 65-75°F for reliable germination.
Transplant hardened seedlings to cell packs once they develop true leaves. Move to garden soil after the last frost date, spacing plants 4 inches apart in partial shade with moderately moist, well-draining soil at pH 6.0-7.0.
For cut flowers, harvest stems in the early morning when the lowest florets on the spike are open but the upper buds still show color. Cut just above a set of healthy leaves to encourage new flowering shoots from lower leaf nodes. Individual flowers can be pinched off for edible garnish once fully open.
Pinch the main stem early in the growing season to encourage branching and a fuller, more compact form. This creates denser plants with more blooms rather than tall, single-stem specimens.
