    Curt Hanson's Crintonic Garden Catalog said:ALPHA QUADRANT
    05 ML 39 SE NOC
    WHAT ME WORRY X SUPREME EMPIRE
    Facilitated by a new generation of innovative technologies, ALPHA QUADRANT represents the very latest advances in sophisticated engraving techniques. Exquisitely precise, this crisply sculpted cultivar further develops the SUPREME EMPIRE grex. Full-formed and extremely symmetrical, these 5-1/2" flowers are boldly reflexed and strongly pinched. The dynamic clean lines manifest a Zen simplicity not compromised by a busy gold edge. The color is a bright golden yellow with a precise, deep-green throat. A wonderful garden plant, ALPHA QUADRANT has a robust constitution with tall, elegant, thick scapes, and exemplary four to five-way branching. Alas, thus far a difficult parent in the garden.
