Your favorite roses & make roses more winter-hardy

strawchicago 5a ILMay 20, 2014

I hope to see Ann's Mermaid rose, and Mas' photos taken with her new camera, and Seaweed's bouquets from Southern CA ... that's why I start this thread.

Also to post ways to improve roses' survival in cold zone. Last winter was brutal in my zone 5a, Chicagoland, with temp. dipped down to -30 below zero. My kid had many days off from school because of the extreme cold. I don't know how many roses I lose, until mid-June ... it takes that long for roots to generate new cane.

Some public Knock-out roses died this winter. Below are pictures taken in my garden, May 20, to document factors that contribute to roses' hardiness in cold zone. Wise Portia was a tiny sprout in mid-June years ago .. I almost killed it with my grapefruit experiment in Feb. But as an Austin rose, Wise Portia is vigorous this winter:

My minor in college was chemistry .. so I like to do experiments. In my freezer, the frozen corn and oatmeal are loose in their bags, versus rock-hard ice-cream or pudding. I noticed that the bag of compost & manure (loose organic matter) froze less than the bag of sticky-clay-topsoil. My soil is heavy clay, which freezes into solid ice block, thus destroys tender roots.

I got Sharifa Asma & Jude the Obscure from Heirloom rose sale 1/2 off end of July. I grew them in pots as tiny bands, then transferred to the ground right before the ground freeze in Thanksgiving. In the holes, I mixed crack corn ($3 for 10 lb. bag from the feed-store), plus gypsum & bone meal for Sharifa Asma. For Jude the Obscure, I mixed pine bark chunks & bone meal & gypsum in the planting hole. Both survived -30 below zero harsh winter, with Sharifa beating Jude in vigor. Below picture of Sharifa Asma is taken this spring morning, May 20 in zone 5a:

In recent years, there's a new probiotic "Cardioviva" which decreases LDL cholesterol by 11%, also lessening the chance of infection by the bad bacteria Clostridium Difficile. From WebMD: "If you take antibiotics to kill bacteria that cause disease, your medicine may also kill the good bacteria. This allows C. difficile bacteria to grow in your large intestine and release toxins." See below link for the probiotics recommended by Prevention to fix particular ailments.

I'm a firm believer in beneficial bacteria (probiotics) both for humans and soils. I was cured of life-long yeast infection by the probiotics recommended by Prevention Magazine called "Fem-dophilus" by Jarrow. In growing roses, beneficial bacteria from manure & compost also suppress pathogenic fungi that bred on soil, to be splashed up to leaves and colonize in black spots (BS).

Comte de Chambord is known as BS-prone. It's hardy to the tip in my zone 5a. Now is healthy, despite my foolish experiment years ago of putting acidic alfalfa meal that made it broke out in HUGE black spots. Comte de Chambord has been clean for the past 3 years, with ALKALINE topping of manure & compost.

Even after the ground freezes, the leaves can be easily broken up, but it's hard to break up a frozen chunk of heavy clay. The holes where I mixed half-rotted leaves with soil, also gave hardy-to-the-tip roses, despite -30 below zero. The roses are: Stephen Big Purple, Frederic Mistral, and Sonia Rykiel. Another person in cold winter mixed half-rotted-straw in the planting hole, with success.

A person in zone 4a remarked that it's the dryness of cold winter that kill roses, rather than the low temp. I agree, if the soil is loose with organic matter (leaves) .. that insulate the roots from being frozen and destroyed. Plus leaves keep the roots moist. Below is Sonia Rykiel rose, hardy to the tip, picture taken May 20:

Wow. You are quite adventurous. I love experimenting but you certainly are the pioneer. I still need to venture out into using my new camera but I went out this morning and took pictures with my phone of the roses that are super winter hardy. I don't do any winter protection even though every year I say that I will. The only winter protection that I do is move the ones that grow in pots to the garage. Here is a list of my most winter hardy roses based on this year's brutal winter:


Therese Bugnet

Purple Rain (this little rose is a tough. She had no winter damage whatsoever and was the first to show buds)

Break O'Day (hard to find but well worth it HT. No winter damage either)

Sharifa Asma (always reliable)

Celsiana (I think she must have spent the winter in Florida b/c she did not have any winter damage and has the most flower buds that she has ever had)

The Fairy.

Here is a picture of Purple Rain which I got as a gallon plant last spring from Chamblees. It is loaded with buds.

I pruned Sharifa hard this year (don't even know what was my thought behind it b/c I do want her to have height. Won't be doing that again. She usually grows to about 4' tall.

Hi Mas: Your pictures by phone are FANTASTIC !!! I'm sure your new camera is even better. My camera is old & cheap, under $200, Olympus from Sam's club.

Last year, around July 20, I bought HUGE bag, 55 qt. of Moisture-control MG potting soil from Sam's .. for only $5. Normal price is $10, but they lower by 1/2 the last 2 weeks of July. My husband said we should had bought 10 more bags !! I saw these huge pots at Sam's club, but I'll wait until last weeks of July, hopefully they'll be 1/2 price.

Mas, I love how you interplant annuals with your roses, very pretty! Your Purple Rain and Sharifa Asma are very healthy & lush. I looked up your Celsiana rose, wow, I wish I have that rose: Damasks, hardy to zone 4
Semi-double, soft pink blooms with attractive golden stamens produced in small clusters on a graceful bush with grey-green foliage. An outstanding rose with magnificent perfume.

We got hail storm last night, 1/2 inch. in diameter ice balls, but did not damage the roses. This morning, roses broke out in buds. Below is Marie Pavie, the earliest to bloom and the most disease-resistant in my garden. When in bloom she's the most beautiful in my garden, and beat my daffodils, tulips, lilacs, crabapple flowers, and forsythia.

Thanks! One of these days I'll learn to use my real camera. I've had the same camera for ever and ever. Last year we had a photo class at the local Rose Society. Unfortunately my camera did not have any of the basic features that were needed. I went to ebay and bidded on one of the good (but still basic) cameras.

I like complimenting plants with annuals for seasonal interest. I just like to have something blooming all the time and a lot of them self-seed. I planted cosmos about 5 years ago and I have it every year b/c it self-seeds reliably for me w/o being weedy. Same with sweet allysium and even petunias. I have a hanging basket that have gotten the same wave petunias three years in a row just b/c i just let it be. I guess it pays to procrastinate sometimes. :)

I hope you get your pots. I bought some huge pots at Costco about 8 years ago and they are still at the front of the house looking great. They are worth it.

I think you would very much like Celsiana. It is a beautiful rose (once bloomer though). It is in the toughest area of my yard where nothing thrives but don't say that to her. She just plugs right along. B/c I gave up on that bed a while ago and just got around to redoing it this year, many times she gets no care at all, not even fertilizer. She is very healthy too and smells heavenly. Are you sold yet? :)

We've been getting the hail and storm for a couple of hours now. I hope they don't get my hostas too bad. They look fantastic this year. This here is one of them: Sum & Substance

Hi Mas: That's a lovely combo of plants in front of your hosta. I like your light-color hosta, and the purple salvias .. it's like a painting of a garden.

Your cute Charlotte rose is a compact Austin ... I like roses in cold zone since they remain small & easy to plant perennials in between. It took me 1/2 hour to weed my rose beds, versus THE ENTIRE week just to dig dandelions from the lawn. Lawn is actually more work than rose gardens.

Thornless roses beat the hardy perennials since they have 4 flushes per year, plus can withstand last winter of -30 degree below zero in my zone 5a. Below is a thornless seedling of Yves Piaget, picture taken May 20:

Below is an early spring picture of Yves seedling that show the thornless branches & green-to-the tip through zone 5a winter. Burlington Nursery in CA has over 100 variety of thornless roses to choose from. They are worth growing & safe for children and pets.

See the link for thornless roses $11 for band-size (large roses), and below link for thornless mini-roses, $7.50 at Burlington nursery. The shipping is cheap, since she uses flat-rate boxes.

thank you for the compliment. I am a major plantoholic, though roses rule, I still like to plant a bit of everything: perennials, shrubs, annuals, bulbs, etc.

I can't believe that your Yves looks so good. I've killed that plant in two different gardens. Granted, the second garden I think I planted her in the wrong area (poor drainage) but Betty Boop is planted there now. But she is not thriving at all so I will try your method of adding wood chips to improve the drainage. It is constantly wet.

Do you have roses blooming? I have a few that I overwintered in the garage. From the ones that grow in the grown, Nearly Wild bloomed over the weekend. Hansa opened a few blooms today.

Hi Mas: I checked your "Nearly Wild" rose in HMF ... That's a cutie with so many blooms. How's Hansa fragrance compared to the fragrant Austin roses? I adore Hansa's deep pink color.

My Sharifa Asma has been blooming. Knock-your-socks off scent, I'm seriously addicted to its fragrance. Last year I put too much gypsum on Sharifa Asma and it took away its fabulous scent. eHow stated that phosphorus is what impart the scent & flavor, so I put lots of bonemeal (high phosphorus) in Sharifa's hole before the ground froze.

I'm leaning toward more Austin roses ... much hardier, and heavenly scents ... no perfume can match. People spend billions in the perfume industry, while roses are so much cheaper & much better smelling.

Hansa is very fragrant. Most of my DA's fragrance lean more towards myrrh, while Hansa has the classic rugosa fragrance, which I think resembles more the classic attar of roses.

One of the rugosas that is just absolutely heavenly fragrant is Rosarie de l'Hay. I don't grow it b/c it is a big bush, but it might be worth it. I came home from the rose society with the cut blooms from this rose from one of the fellow rose society members and I just kept sniffing it all night long.

I know that you mentioned that rugosas don't like alkaline soil, have you tried growing them before?

My Sharifa isn't blooming yet. The poor thing had to put on some growth after I pruned her heavily. Never again.

Hi Mas: The library, 5 min. away, has a hedge of Rugosa. They bloom once a year (very few blooms), and the rest of the year they look like yellowish sick eye-sores. Our water is too alkaline, pH 8, and our soil is heavy rock-hard clay, and become water-logged with poor-drainage.

Rugosa can tolerate alkalinity if it's loamy soil. Rugosa is known as "beach rose" since they do well in sandy soil and tolerate drought.

Seaweed sent me hundreds of pics. for the past year ... too bad her lap top can't post pics. that well. Among her 160+ roses, these are the two I like: Charisma next to liquorice scented Julia Child:

I have this white rose climbing up the pine tree. I don't know what she is. She was the root stock that Rosa Mundi was grafted on. I tried killing her a few times but after seeing that it was not really bothering Rosa Mundi and the blooms and hips were so pretty I've left her be. I don't think it is multiflora, at least the common multiflora b/c it has very big/long hips and larger, solitary white blooms. I would love to id her. She climbs on the pine all on her own. I've done nothing to help this rose. From afar it looks like I have a blooming pine. :)

Hi Mas & Seaweed: I think Seaweed meant to thank you, Mas, for those nice pics. in your garden. Seaweed's eyes have a medical condition with double-vision, hard for her to keep track of who's posting.

What I like the most about your pics, Mas, is that they are in a natural setting, it's like being in your garden. You have such perfect soil, all your plants are lush & green. My white pine is yellowish in heavy clay, but the white pine that I fixed with sand is less pale.

My favorite most hardy rose is Comte de Chambord, magnificent scent that beat any expensive perfume. It survived last brutal zone 5a winter, even though I moved it to a raised bed late fall before Thanksgiving. I did that since it's so short that the bunnies ate its blooms.

Below is Comte de Chambord, taken May 28, it has 8 buds for a tiny plant less than 1 foot.

Thank you! I try to amend the soil every year by adding different soil conditioners. I still have mostly clay covered by dark mulch. I read somewhere that mulch forgives many sins and how true that is. It makes beds look finish. I think my white pines are getting scraggly as they grow.

So excited to hear about your CdeCH. I ordered Comte de Chambord and Blueberry Hill from Heirloom. Should be here any day. Does it always stay small for you?

Hi Mas: Comte de Chambord as own-root is small for everyone, including Kittymoonbeam in CA. It's very small for me, since I keep cutting the blooms, such fabulous scent. It's so compact and VERY cold-hardy. The grafted version of Comte is worse: disease-fest & and declines as it ages.

I like own-roots since they improve with time. Grafted on Dr-Huey are vigorous at first, but a decline in vigor later. Many of my neighbor's grafted-on-Dr.Huey died this past winter in my zone 5a.

You got Blueberry Hill? I'm always impressed by its pics. Can't wait until you show me that one blooming. Below is Comte de Chambord bloom, lasts 4 days in a vase ... I sniff that at least 10 times a day.

It looks beautiful! Thank you for letting me know about the own roots vs. grafted on this one. So glad that i got it on her own roots. I got both this one and Blueberry Hill from Heirloom. They are supposed to get here this week. I got they don't suffer with the high temperatures getting here.
