Years Trialed: 1999

Good Qualities

Strong stems (3); Large heads (2); Uniform flowering (2); Earlier than Sunbright by 7 to 10 days (2); Early flowered in 50 days; Attractive stem color, flower heads approximately 4; across; Will definitely grow again next year; Seems pretty much like ‘Sunbright’; Stems stronger and a little shorter than Sunbright; Good contrast of colors; Excellent flower size; Good color and overlapping petals.


Not as much interest in these, most consumers I spoke with would rather have 1 larger bloom over 4-5 smaller off-shoots; Not enough breaks. Seemed to be nutrient deficient. My customers didn’t like the color; Variable timing; A little short, cupped flowers;


Similar to Sunbright (2); Smaller diameter of branching stems, but branching stem length 12-14; Didn’t seem to bloom earlier than ‘Sunbright’; One flower per plant; This plant was a little more “coarse” or stocky than ‘Sunbright’. I prefer ‘Sunbright’; Looks like many other cultivars but was really early.
