Sorry, I don't know, but I'm answering to bump up this post, hoping someone else will. I have Pink Clouds as a root stock for one of my climbing roses, so I never see it. The photo on HMF looks likes a massive array of miniature blooms and foliage. Is this the rose you meant? Pink Clouds on HMF

Mine would like to be ramblers so far

I got this rose from Rogue. They claimed it was the large-flowered climber, but it turned out to be the one with miniature, single dark pink blooms shown in the link above at HMF. I am thrilled with the mistake, as I love the version I got and think its probably more beautiful than the large flowered one! I have had it about 3 years (it was rather large when I got it) and it has been growing quickly into what I would say is a small rambler - think Phyllis Bide, for example. I thought it was a once-bloomer, so never bothered to dead-head, but I see on HMF that they claim it reblooms, so I guess I better get out there and start dead-heading! It'll be a big job because its an absolutely prolific bloomer, just covered in flowers. Mine blooms fairly early in the season.

Hope this helps!

Sequoia Nursery grew it as a large shrub, pruning it back to keep it "boxed". Mr. Moore created and released it in the late 1950s in response to the "Ragged Robin" hedges other nurseries offered at the time. If you shear it as you would a regular hedging bush, you can keep it boxed. It will grow like a Banksiae, so it has to be sheared or pruned regularly to keep it that way. Or, train it as a rambler, tying it to supports and it will shoot long growths as laterals. It IS vigorous, roots easily and makes a really great root stock.

Roseseek, do you know if in fact it does rebloom?

It's like many which combine genes from once flowering and repeaters. In the right climate, the right conditions, with the suitable maturity, it CAN rebloom. It can't be guaranteed to rebloom everywhere and every year. I grew Silver Moon, a once flowering LCL in Newhall, CA for 18 years. After it was six or so years old and attained "mountain size", it regularly flowered every spring and continued scattering flowers until late fall, but it isn't a "repeat flowering" type. Pink Clouds CAN do similarly. If your "spring" is long and mild enough so roses like Banksiae will continue flowering for weeks to months, you can probably expect the same from PC. Where that once flowering period is cut short by the sudden, extreme season change as if someone flipped a light switch, it will probably do what the others do and stop when the heat hits.
