Thank you all for your input. I won't get any more tree roses but I was intrigued about the moss. I have a climber that also gets moss from the same tree. Can you tell me why it's bad? I didn't know about that

The moss traps moisture, debris, dirt, insects and disease spores. I'm not sure if it can actually feed from a rose, but if sufficiently dense, it can shade out new growth like weedy ground covers can and it can help to trap the moisture around the canes and foliage which can make the conditions more favorable to insects and diseases.

You should probably check whether you have a cane borer in your area. We have the Pacific Flat Headed Apple Borer here in the West. You can see other sites about ithere , here and here. It attacks virtually anything and is attracted to sun burned wood. It lays its eggs around the scalded/burned area. The maggots hatch and burrow themselves under the bark where they eat the cambium layer, the circulatory system of the plant. They work their way downward, toward the bud union or roots. Once they hit that level and work their way around the cane or plant, the only remaining living part is the root system. It's entirely possible your standard damage is due to this type of issue, combined with the sun scald.

If the bark is split and black, try prying into it with a knife. If you find dried powdery tissue resembling cocoa powder, it's the "frash" or excrement of the borer maggots and used to be living circulatory system, cambium layer. Once the cambium is dead, for whatever reason (freezing, burning, physical damage from borers, girdling, bending, breaking, etc.) the tissue above it is doomed to die. Intense, direct sun shining on a point on the cane can cook the cambium layer under the bark, attracting the borers to do their jobs, or simply killing the tissue above it by starving it for sap. Humidity has nothing to do with it. In my old Newhall garden, the humidity was often single digit and the Flat Head borers were legion. The best defense against them is to keep a good foliage cover on the plants to prevent too extreme exposure to the direct sun. For standards, using the trunk protections used by orchardists for the trunks of their trees can help. White wash the trunks or wrap them in protective coverings to shield them from the direct sun. For the heads, just maintain as good a foliage cover as possible.

Don Jaun should do really good for you. As far as mini's go, I have all my own root mini's in 7 1/2 gal. nursery pots with GOOD potting soil. They do fantastic in those pots.

Give your Don Juan plenty of room to climb. It will need support pretty soon.

Could be a rose seed but they would like take several years from spouting to send up a cane like yours. Can't wait to see what the flowers look like. Those buds should start too color up soon.

A lot of my band roses do that once they settle in. Dakota Redwing has a cane that's 4' tall now when the rest of it is still about 1' tall! It looks pretty silly, but also very healthy (and with some lovely looking buds "ripening"!). Roses are strange :D

Beth sounds like me. Or I take one rose of my WL and add 3 more in the process.

That's it - I'm done - my wish list /order list for this year is done! I am not (NOT) going to make anymore changes - absolutely NOT! (lol) I narrowed it down to 33 which includes 2 replacements for wrong deliveries. I put the order in for 20 today for delivery beginning of November. Think I am going to start preparing the planting holes - loosen up and get rid of all the big stones - will definitely make planting easier when they arrive.

SoFL Rose z10

It's not just the cold that causes this. Extreme heat and drought while the rose buds are forming can cause it too. I never have freezing temps or cold temps of any kind really, and my roses develope these all the time. Some roses are more prone than others (elegant fairy tale for example gets them very often). I just got one on my Eden rose and temps have been ranging from the low 90s to the mid-low 80's so not even a tad bit cold.

I have a few roses doing that now. Mostly the many petaled ones are temps have been all over the map. We just went from fall temps to this wretched heat and humidity. Jolie is bullheading a lot right now. No thrips in there.

I've been a gardener or around gardens all my life, so it was inevitable I'd grow at least something when I got space of my own. My father grew up on a farm and we always had an extensive vegetable garden in the back as well as fruit trees, and he coached me patiently on techniques in growing those plants (my brother never took to it). My mom planted annuals and other flowers around the yard, and for a short while had some body bag roses that she tried to grow in one patch, but as we've all seen from many of these body bags, they didn't survive long (getting mowed over by my father by mistake probably didn't help). So like most of the world, I grew up with the notion that roses were fussy and not much worth bothering with.

When we bought our first house, I was determined to plant the entire front lawn in flowers and blooming trees, and the nursery recommended some shrub roses as landscaping. I didn't distinguish them much from any of the other shrubs or trees except to note that roses weren't that hard to grow after all. Champlain became my "gateway drug" rose because of this.

When we bought our current house, I was thoroughly hooked on perennials and bulbs and selected a house at least half because of the generous sized yard (with NO Virginia Creeper, curse the stuff!). I planted a Champlain of course, but didn't think much about roses for the first year. Then I got to looking at the main back garden and thinking that it needed more height. Hmmm, roses are bushes, they have height. Enter a local nursery with very reasonably priced HTs and my introduction to David Austin roses as well. Once I appreciated the diversity and still relative ease of most roses, I was truly hooked. Not that I don't love my perennials and bulbs as well, but they don't really take much of my thought any more (and I don't hang out on those GW forums - they're usually easy enough there's not much to talk about). Always plenty to talk about with roses, and the nicest people to boot!

When I was small, I used to visit my favorite aunt wuth a huge rose garden full of only 1 type of red rose . As it bloomed my aunt would collect roses and made rose syrup out of them and then give a big bottle of rosé syrup to my mom. That used be the only summer drink I loved . That's how it started for me. My mom is a gardener too but not for roses. She is into veggies a lot.

Looks good Jim, you should have panned around a bit to show us a bit more of your garden:)

I bought this one first thing this year, poor thing had to live in its pot for months and she still put on a wonderful show for me! I got her planted now and I can't wait to see what she does

I hope Meilland send this rose to us in Australia as I think it would be as popular as the original Pierre de Ronsard/ Eden Rose. I told my daughter in Japan that it may be released there and she is very excited, as she loved PdR in my garden and now has 3 of her own.

Well, I can tell you, my SIMSALABIM is not a large bloom. Most of them average only about 2" or less. Kinda like ABRACADABRA. They're all more like minifloras.

Beth, there's a write-up in the Horizon 2015 about this rose.

I haven't watered them since last Sunday--and that was just to avoid burning the leaves when I sprayed them with fungicide.

It does appear as thou it will stay cupped until the petals fall. I just love that flower. What a nice surprise. So many Austin roses have leaves in groups of seven. I think Kate has the right id. with Crown Princess Margareta.

Thanks Sara-Ann. What I suspected. I am very entranced with the form of Michaelangelo and the shade of yellow looks mellow on my monitor. Might be exactly what I've been searching for the last 20 years :-)

Dinglehopp, I am perusing ADR winners and saw Berolina listed so that puts it head and shoulders in health above others. Apparently most strict criteria are applied to achieve ADR status and it can be revoked!

Some of them were one of a kind or ones that I won't be able to purchase anymore. Like my Sheer Stripes from Mike Lowe...
