Blc. Ranger Six 'A-OK' FCC/AOS is a classic big white with very high quality flowers, as befits the award. Not particularly vigorous, this could explain why it is not seen that frequently, and does not appear that often in crosses. The flower is very large. It also has the habit of losing roots, so can't be recommended for this reason. It is fragrant.
Plant height is around 16 inches, fairly stocky, upright and stiff.
