High Noon (Climber) (Soeur Therese X Captain Thomas): Deep yellow, cupped blooms, resistant to wet weather. Flowers continuously from June to October. Ideal for arch, pillar, fence or wall as it rarely exceeds 9 ft. (Lammerts, 1946.)
It is incorrect to say this variety is once blooming as it blooms in flushes throughout the year. I have grown several plants from different reliable sources and they have all had pretty good rebloom. As with most climbing roses, you will get more blooms if trained horizontally rather than upright.
Thank you for sharing your experience with this rose. Checking on the Vintage Gardens website I found more information about the rose in addition to its reblooming habit and have updated the rose page in the HMF database.
Although your sight lists High Noon as being good for gardens in zone 6 and higher, I would like to let you know that my plants of high noon have survived for the past five years in zone four in some of the toughest winters (little to no snow cover) and without protection. I find it grows better and stronger than the ever popular golden showers.
