Kardinal (87). vigorous healthy grower. A lovely dark red, most blooms are well formed but possibly a little small as yet. An excellent cut-flower/bunch variety. Repeat flowering very rapid. However some die-back has been experienced on new plants but it disappears in second year.

Ross Heathcote, New Roses in Victoria. 
Kardinal  Possibly the best red rose introduced in recent years, may be slightly small for exhibition, has 35 petals and every bloom comes perfectly. Blooms get fatter with feeding. Growth is good on a healthy bush. Slight fragrance, an ideal bunch rose.
