17 years ago

For Immediate Release:

Boston June 13th 2006. It's official! Geranium Rozanne is UP FOR THE COUNT!!! you'll hear no mutteriings of "I coulda bin a contendah" from her. no sirree. Now, we all know that the REAL, always-comes-in-1st contendah- is Corydalis Lutea. But since that is genetically a given, Rozanne seems to be the clear favored leader in the field of all the other longest bloming Z.5 perennial competitors...

My money's on you, rozanne!Go get 'em, girl!

"Rozanne seems to be the clear favored leader in the field of all the other longest bloming Z.5 perennial competitors...My money's on you, rozanne!"

The LONGEST blooming z5 perennial will be Dicentra eximia.
It starts about 2 months earlier than Rozanne and stays till Rozanne stays. (In my z6 garden from April till end of October, sometimes early November).
Rozanne is newer and probably prettier, but good ole Dicentra is a real workhorse and I'd vote for it.
I know, I know it never will be a winner in a real contest judged by the industry professionals because it's so common and reseeds, so nurseries can't make much money out of it.

George, What do YOU know??? you're in Z.6b, NOT 5, my friend!! No, all kidding aside, dicentra exima over corydalis lutea? i don't think so. not for me. dicentra exima pops up a good month or more AFTER lovely elegant Ms.Cory. or did you mean the longest blooming z.5 perennial AFTER Ms. Cory?

Geranium 'Rozanne'
Q

You should see foliage rather quickly. 'Rozanne' is a prolific bloomer for me with part sun/full sun half/half during the day with moist soil. Cutting back produces a nice, neat mound of beautiful foliage. It may take a few weeks for blooms to appear again. I'm basing my experience on my own 'Rozanne' that gets part sun all day and is in moist, well-draining soil. Something that I do in the cottage garden is use container plants (small to medium pots) in the bed where I need a little distraction while perennials emerge. Then, when the perennials are looking good, I move the container to another spot. This prevents disturbing the soil in a tightly packed cottage garden. Right now, I have a container hosta in the bed with the 'Rozanne' to provide interest while waiting for the phlox 'David' to bloom. In my deer resistant meadow garden, I grow spring annals that I pull up by the roots to remove when the summer perennials are going strong. Different setting with lots of space. Cameron

Experience with Rozanne Geranium
Q
Comments (26)
well, if you look at the supposed dimensions of Rozanne, they never exceed 90cm x 60cm....and measurements of 60cm x 40cm are routinely expressed.but mine is well over 3X that size with no especially treatment. Generally, when these measurements are addressed, they (plant breeders) count a significant area of crown and allow for a bit of outflung straggling. Well HB is still has that scandent habit but (so far) seems to remain a little bit tighter around the main crown, only throwing 4 or 5 longer stems. Time will tell, but Rozanne definately seems to get bigger, year on year, even though the crown remains quite tiny. I can only speculate a humongous root system underneath the soil and would be tempted to take Van Noort's estimate with a largeish pinch of salt. Stick with Sweet Heidy - this one really seems to remain mannerly....or, G.procurrens 'Blue Sunrise' - another promising long flowering geranium.

What's eating my Geranium 'Rozanne' blossoms?
Q

I have planted Rozanne in the outer garden to test/tempt the deer. They browsed a few Japanese iris blooms last night, but ignored the blooming Rozanne. My Rozanne is a bit leggy from being in a nursery flat, but I just can't bear to cut it back yet since it's new to my garden. Don't know what's eating your Rozanne. Cameron P.S. If you want a BLUE geranium, try 'Brookside'. Mine came from Bluestone last year. The color perfectly matches my platycoden (look carefully in the lower right of the photo):

Still no sign of my hardy geranium - Rozanne
Q

I had my Rozanne in a pot all last Summer. I transplanted the plant into the ground last October. She threw out a few more blooms...last one in November I believe. We had a wicked winter her on Long Island and all I could do was hope for the best. After the weather started to finallY warm up I saw a little bit of growth. Now I've got quite a bit of growth...maybe once your weather starts to warm up you'll get some growth back...one can always hope right? Ciao, OITGAD

For some reason, I cannot keep Dicentra exima or Corydalis lutea alive, so my vote is for Geranium 'Rozanne'. I'm in zone 6 though. Persicaria 'Firetail' or 'Taurus' is second though-very long bloomer.

Funny, everybody has a different experience with the same plants.
My corydalis goes dormant by the end of April and persicaria (Painter pallettes) for whatever reason is semi-annual/semi-perennial for me. One year it blooms like crazy, on another it takes sabattical and not sprouting at all or just very late in a season, like in July.

wow, george, that's so interesting. i wonder, with your experience with the corydalis, if it is a particular STRAIN that has that dormancy timing?...
I wonder, if you planted a plant from MY corydalis- if it too would take on the dormancy habits of yours, or if it would behave like MINE and bloom through oct. ?? maybe i'll bring you a small plant when i see you this wkend... and you can post the results of the experiment later!

My heavens! The 50 or so Corydalis Lutea plants which have established themselves in a neighbor's stone wall bordering the street have been blooming since last June and are STILL (It is JANUARY!!!! folks!!!!!) blooming!

Oh my....it looks like Corydalis is the winner!

All these reports & George's pictures...this is starting to feel just plain weird. I enjoyed the beautiful weather back in October & November. In December, had a little trouble feeling like the Holidays but overall still thought the warm weather was nice KNOWING that it would soon enough be very cold. Well, now it's getting on towards the second week in January & my 10-Day Forecast looks like April. It's no longer amusing...just weird.

PS My friend told me yesterday that her horses are jittery. They've been out in the pasture eating fresh grass instead of in the barn eating hay. She thinks their behavior is weather related?
