"Lovingly known as the Outhouse Plant, this old heirloom selection of Coneflower is still seen in gardens today."
Turns out my best friend gave it to me a couple of years ago, but I completely forgot.
There are no seeds, unfortunately, but it propagates well by simply dividing the root ball. IÂm definitely going to work with it to give it a better spot as right now itÂs literally inside a willow.
Have a look at this picture of them. (note: not from my garden.)

Bigger! About 3" across now, and seems about half open. I think I'm a bigger fan of water lily types (is that the right term?), but I'm excited to FINALLY see a dahlia that I GREW! I took another picture, but it was almost dusk and it came out crummy. I'll post it anyway, but don't laugh...I'm at a bit of a disadvantage, I only have a camera phone right now (can't afford new camera because spent all my money on stakes and twine and plants and manure and mulch and so on). I'll have my photo-talented neighbor come take a picture tomorrow or the next day. It's not quite as deep in color as I thought it should be if it really is Cornell, but I'm sure I'll learn more tricks as I go along...this one is kind of a dull dark red at present...
Here's yesterday:

Here it is today, sorry for the bad pic, but I'm lucky I got to take one today. I actually left work early so I could see this in the daylight (normally get home after dark)

And bonus - Hulin's Carnival has a nice plump bud, with just enough of the petal peeking out to see the purple specs. YEA!
Couldn't have done it without all the help you and everyone has so kindly offered. THANKS A MILLION! I'm hooked.

A DEEP watering should bring them back to life. Fertilizing will not help a wilted plant. Flowering
plants need more water. If you want to fertilize
just make sure you are supplying more phosphorus
than nitrogen e.g. 5-10-10 or 5-10-5 or 10-20-20 etc
With more nitrogen the plant will produce more foliage
and less flowers. Also the development of viable
tubers is compromised for next season.

We have had a fair bit of rain here too. Yesterday was a decent day so I fertilized again. I try to fertilize my brugmansias every week with a higher middle number fertilizer, and yesterday the dahlias got it too. I stop fertilizing by the middle of August, as I do not want to encourage growth, but rather let them settle down and clear out their system from the "performance enhancers".

They look wonderful. I used the wood tags with a marker and the names of the tubers washed off. I have no idea what I have. Will up load some later for ID. We have just had days of heavy rain with flooding etc. The soil is like soup. I wonder if I should fertilize again?



I have both Iceberg and Snowbound this year, but neither are near budding yet. Iceberg is supposed to have pinkish tips to its pettles, so I'm guessing what you have open there is Snowbound. Iceberg is 12" diameter, Snowbound 9". Iceberg is 36" tall, Snowbound is 48".
Short stems can be a problem. I had that problem last year with my Purple Taiheijo (which is sister to Iceberg btw.)
You can disbranch, or if you have buds above the blooming flowers (which you appear to) simply go ahead and remove the bloomed flowers for your vase.
It can take a week or more for a bloom to fully open, especially the AAs. I recently had a 4" bloom that took >2 weeks to open fully.
I don't have a lot of cutting experience for vases, but I cut them when they look nice...who cares if that's 50% open or 100%.
Mine did not continue to open after I cut them. YMMV.
Congrats on growing such beautiful Dahlias!

Plantlady2008,
How do you keep the Emory Paul(EP) from wilting? I have an EP also, but it is not as huge as yours. Mine is in a pot and this year flowered in early June. If you ever introduce your seedling 0601 I would like to obtain one.
I also have a Big Wow which flowered more early this year. I don't have pictures because I don't know how to download from my cellphone, lol.

fleur guy-- 6 up or 10 up or however-up means that's the number of blooms you allow on a plant for the whole season. In England the hard-core growers keep the AA's- or Giants as they're known over there to 4-up... 4 blooms per plant per year. They grow upwards of a hundred of a single cultivar so they can get blooms enough for a show. We have found that with some of our giants we can grow them 10 or so up & still have a giant bloom, but some of the older cultivars don't reach size unless you force them to by disbudding & debranching.
Sturgeonguy- that Emory Paul pict. was taken about 13 years ago. The tuber was just planted in the garden in full sun. It had to have been about the middle of Sept. when we got the bloom as we entered it in the Whatcom Dahlia Society show which is pretty much always the 2nd weekend in Sept. It wasn't started indoors or anything like that-- we didn't even have a greenhouse at that time. The problem we had with Emory Paul was that it got later & later in the season before we got a bloom or 2 off of it & it's a mule-- can't get seed from it at all -- so we stopped growing it when we got really serious about hybridizing dahlias. Wish it had co-operated more as it would have been great it get some of that size into our breeding program!
As for getting into our program-- you have to be an AA sized dahlia >:) We grow all our own for 5 years before introducing them-- with one other friend of 35 years that we let grow for the last year or so before introducing just to see what they will do in another garden. We also put some of them into the ADS trial gardens all over the US in the last year before introducing- that's how Wyn's Sensation won the Darrill Hart medal in 2006- highest scoring A sized dahlia in the trials. Some of our cultivars will hit the trials in England next year- we'll see how they do over there.
amaryllis- we put the Emory Paul bloom into a bucket full of water & floral foam to enter it in the show. They don't wilt in the garden if you keep them well watered.

Thanks JROOT. My garden is mostly tones of purple. We bought the dinner plate collection two years in a row. So we got a pink in the collection. Last year my wife also bought another collection. It had Miss Rose Fletcher in it. I put the whole clump in to the garden this year. And you can see the resaults. Lots of pink blooms. I do like pink. But I like all of them.

Miss Rose Fletcher... brings back memories- it was our first dahlia in 1965! A friend gave us a clump we cut it up & every tuber made another huge clump & so on. We don't have it any more but now with around 7,000 dahlias you can see where the addiction started!








wow
That's quite a transformation, Russ. A nice one, too. :)
