'Madame Isaac Pereire' rose Reviews & Comments

This Bourbon is one of those very few historical roses wich have passed the test of time and after more than 130 years she's still wildly popular and it's no difficult to see why.
The real Mme Pereire's first name was Fanny and she was the wife of a very rich French banker, Isaac Pereire. They gave very much money to good deeds and charity. I'll add a photo of the real Mme, Fanny, Isaac Pereire but now back to the actual rose :
I've had this rose for decades and she's still my favorite rose. Her huge perfectly quartered baroque flowers are simply unique, no other rose has such flowers. And yes there is the scent, wich blows you away. It's a wonderful blend of old roses with raspberry and yes it's very powerful especially in warm weather with little wind.
I've grown her as a shrub for years but now she's against my garden stone brick walls and this is probably the best way to grow this magnificent old Lady. Just trim her as horizontal as possible and she will reward you with lots of flowers. I feed her every month starting at March and i continue till August. I give organic mineral granulated manure, a handful each month and ( this is important) a lot of water! I water every day especially when in full flush and between flushes. It gives her the power to take in all those nutrients she needs to grow and rebloom. Against the walls she reaches 3X 2 meters but she's going to get bigger because it's only her third year. She's very hardy and her only weakness is that she's a little bit prune to blackspot but not worse than most modern varieties. After three years against the wall she hasn't developed blackspot wich my other specimens did growing as a shrub. So that's it! I can't tell you enough how much I love this wonderful old Lady.

Thanks for sharing your experience with this rose! I'm growing its daughter rose "Sandringham" but there doesnt seem to be any information on its growth characteristics, so I thought it best to look at it's parent. From what you say I can certainly see the resemblance in flowering, fragrance and vigour!

Now that yours is a little more mature, how would you say it performs in terms of bloom frequency? Specifically, how many bloom cycles are you getting now? Mine is potted and only 2yrs old. I got one good flush out of it and that was it, not a single bloom afterwards.

I'm assuming you're talking about Sandringham, in which case im surprised to hear that! Mine is also potted and had excellent repeat bloom all season. Rarely out of flower even in its first year. Perhaps using a richer, heavier compost might help?

Thanks for your response. I actually mistakenly posted under the wrong thread! Still it might be worth looking into Sandringham. I'm giving more consideration to bloom frequency these days.

The MIP which I grew in CA Central Valley bloomed very well with little or no supplemental water. The bush is a thorny monster and is a good choice to plant on a property line if you want to discourage trespass without seeming to do so. Now, I like thorny monsters, confess to an enduring fondness for 'Othello' among others, which I see as a plants that make a yard interesting.

that was a great report, thanks. I've planted this but I'm surprised to hear you feed it each month, I'm an amateur and been swotting the usual advice which says feed roses in the spring, March/April and again July/August. Been led to believe that that is the 'orthodox' feeding regime and I've been warned off overfeeding them. Do you feed all your roses this way ?

Hi Peter,
Yes i feed all my roses each month starting end of March. I basically use a combination of organic/mineral fertiliser low in Nitrogen and worm compost. Worm compost is the best compost in the world especially when combined with lava powder (volcanic stone which has been grinded into powder).
Lots of organic mulch is the premium key. I water all my roses when weather is hot and dry. Roses can't absorb the nutritions when the soil is dry.
So Peter: Compost /cow manure /lava powder.
Friendly greetings Dirk

I guess frequency of feeding depends on your soil type; sand might well need what you're recommending. I have clay sol, and I feed my plants (mine are all heritage roses) with a commercial seaweed / fowl manure compound. The manufacturers recommend feeding each quarter, but I don't often get around to it more than once or twice a year. I don't use the mix they make specifically for roses, because it contains too much phosphate for my native Australian plants.

Peter,
If it works for your roses? Don't change it! Clay soil is good for roses as long as it isn't too heavy. You can make heavy clay soils lighter with milled basalt fiber/powder. But if the roses are doing fine, don't change it. I never give artificial fertiliser, always organic.
Greetings Dirk

thanks for the advice everyone. This is my first year at a rose garden. I've been gardening for many years and always had the occasional rose but I have my best garden, location and view EVER in this property, so I've gone for it. 15 climbers and numerous roses, mostly DAs. So Ive no idea what works yet :-)
The soil is a rich loamy texture with a base, about 2 feet down which looks like stratified sand and clay but it breaks up like shale when you put the spade into it. I'm also on the coast, my shoreline is a short stroll from the house and this land was once seabed. So I've prepared all my beds with one year old homemade compost using two year old manure, loads of black and rotted leaf mold, rotted household compost and shredded seaweed and this mix is tumbled in my cement mixer with an equal amount of the existing loam. ( it's got loads of worms in it, lovely stuff ). The planted rose then gets a tablespoon of bonemeal as a top dressing.
Every rose has a deep cool base under the planted area, gets at last a few hours sunlight, some, several, but none of them are planted in any darl and overshadowed locations, all get daylong ambient light. And we get any amount of rain, could do with more sunshine but it is Ireland. According to the zone table I'm in 9b :-)
Ive also prepared, since last year, a big tub of seaweed soup for feeding during the season and I did wonder; as all my roses are 'repeat flowering', if I was supposed to feed them more than the orthodox twice a season, because they are expected to bloom so much.

Hi, back again for a little more info. My Isaac is planted in the same well prepared bed as several DA roses, but it has produced miserable growth so far and certainly no buds. It came bare root from DA along with the other roses and it had very sparse canes, it has made very sparse growth but that seems healthy. Is it a VERY slow starter ? This is its first year with me

This is the first year I've used both the volcanic rock dust and the worm castings and the difference is amazing! This year the blooms on my MIP are huge and canes are thick. My soil test showed that I was low on some minerals (boron, zinc, etc,) but I have to believe that they are fine now. I did only apply it in the spring, but after reading your post Peter I'll start doing it once a month. What are you using for mulch?

Second year experience: this rose is in a neglected hotspot, and I was distracted planting new roses. Right at the start of spring, much earlier than most other roses I have, MIP put out her buds. the first few tiny blooms were paper thin and pathetic. I got organised fast with water and fertilizer, and have now had about 8 full size blooms over the next month. She really has responded well to fetilizer and water, (still weedy around base though). She is planted next to Madame Hardy, and they are soul sisters of thin weak leafless canes! A cane of each even reach over and support each other. Now to wait and see is Madame Hardy will bloom.

This rose is drought tolerant. It almost died in wet clay during spring flood, and I had to move it UP HILL to dry & loamy soil. Very healthy & tall & vigorous on August 26 as 3rd-year OWN-ROOT. The second flush in July gave 1/5 the amount of blooms as the spring flush. Will report back if it gives bloom in late fall for 3rd flush.

No repeat so far during fall.

It seldom repeats at my place. This very hot, dry and sunny year for the first time.
