Mine were planted on 40" centers. Unfortunately for me, in light of where they were planted, since they showed their billowing, arching habit their first year and continued the pattern there after, they were removed in their third year. They never had the time to reach their full size potential for me. For your climate, I would imagine planting them on 4' centers would give a continuous hedge look where they interlock at their perimeters. I would go with 5' centers if you want them just touching/encroaching a wee bit into their neighboring Carefree Beautys. Now, in my zone 5/6 garden, my 40" center planting would probably have meant the bushes would just grow into each other a bit by each season's end. I would not go as close as or closer than 3' centers. A Floridian who grows Carefree Beauty could give more perspective on your question.

@rosecanadian(Zone 3 - overwinter in pots in garage) Thank you Carol. I remember I waited a long time to have Osiria, and it's worth the wait. It's a special rose. @Diane Brakefield Thank you Diane. I have two Pompon Veranda just because I need a back up in case something goes wrong with one of them, lol. @CeresMer Zone 7a NJ Thank you. I have a drip system for the ground roses and hand water the potted roses. However, I'm planning to set up a second drip line for the potted roses because it takes too much time hand water many potted roses every day. My rose pics often look good because I clean up my roses before taking pictures. For the feeding schedule, I think you should check with BenT. His roses always have abundance of blooms. I'm really busy with work so I feed my roses when I have the time and don't follow any schedule. My garden philosophy is things will get done when when they get done, lol. @Ann-SoCalZ10b SunStZ22 Thank you Ann. I think Pompon Veranda original was a florist rose so regular rose gardeners didn't have access to it until later. Many beautiful florist roses make me feel like a kid at a candy store and being told I could look but couldn't have any, lol. This rose needs deadheading. I think it will look good as a mass planting 3 plants in a row. However, if the place is difficult for you to access for pruning, you can look at some David Austin roses. I think David Austin intentional bred the self deadheading characteristic in some of his roses because those are meant to be used as landscaping roses and self deadheading is a positive feature. However, these type of roses often won't last long in a vase. Helen

Just a note that the coupon code is now working! (It’s shown on the top of the webpage, and is for today only.) She has a small but great collection, including some hard to find varieties, and the listing includes the root stock info. Shipping is in March 2021. I got a Rouge Royale (on multiflora) - super excited about it, as I’ve been looking for one for 2 years, and it’s always sold out!

It's really hard to tell from that photo. It looks like it's a heat-stressed rose that got bleached out. So we would need to see what it looks like as a bud.
