Ruby Frost

Breeder:
Syngenta
Summary:
A beautifully named cultivar with equally beautiful creamy white bracts with the margins and veins liberally colored ruby red. Some bracts are mostly red with white showing through but the variation does not distract from final appearance. First transition bracts may not have good contrasting color patterns. Bracts and leaves are slightly contorted, but less than with some cultivars such as Avante Guard. Because of the smaller leaves the plants can look sparse as they are growing. The mid-season plants were strong growing and shoots were a bit uneven. Stem strength can also be poor. It may be best to overgrow the plants slightly and use plant growth regulators to even up shoot development and produce stronger plants. This cultivar may be more sensitive to high temperatures than most other varieties and malformed leaves and stems might occur in the highest temperature situations. Plants worked well in all container sizes from 4 ½ up to 8-inch tubs. Foliage is light green and bract presentation flat.
