Antirrhinum ‘Opus Bright Red’

Antirrhinum 'Opus Bright Red'

Trial: Annual

Year Trialed: 2008

Good Qualities:

Very bright, vibrant color (7); Very tall (2); Amazing plants! Some were 48 inches, grew in field with drip tape and 1 row netting, I am still harvesting and some of the 2nd flush stems also exceed 40 inches; Straight stems with good spacing of flowers, straightest of all snap cultivars; Wonderfully long stems with good girth; Strong plant, good rebloom with side dressing of fertilizer; Very fast growing from germination to transplant was about 6 weeks; The head size of bright red was not as impressive as ‘Fresh White’, but was good; Great for taller arrangements, good fragrance.


None (2); Some issues with stems falling over, but minimal; Flower spikes rather short – 6 inches or less, more susceptible to rust than other snaps in trial; Fragile tips; Needs to be staked, blooms are not open at same time on stem.

Similar Cultivars:

‘Potomac Red’ (2), but I like these better.


Would like to see more colors; Most bushy of snap cultivars, good because they weren’t sprawling; Had much better results with these than any of the other Opus series we have tried; The red was outstanding, however, stem length was disappointing, maybe I planted too late, seeds were started on March 21; This entire planting was put in late and not cared for due to a total lack of labor, it was watered, it was subjected to heat stress right after transplanting and developed flowers while quite small, initially, but kept on growing; Flower head = 3 cm.


Used Floralife for hard water; Water and bleach; We had a problem with the tips being very fragile and breaking, it was worse in the summer heat, this fall they did better, we recut the stems when we got them in the barn, put them in fresh water, and that seemed to help a lot.
