F1 Collection dramatically solved some difficulties seen in open pollination varieties, such as uniformity in growth, timing to bloom, flower quantity, stem length and upright flowering habit.
Earlier than Augusta and slightly later than Julius but taller and more branching expected. Promising plants produce high number of flower.
Earliest in F1 line - between Raizan Herald and Raizan No.1. Slightly tighter than Raizan Series but hard and solid stems are available.
