confirm Pinus parviflora 'Adcock's Dwarf' ID

11 years ago

any opinion whether i have the right name on this plant??

any corrections ???

and who was adcock??? .. any history???

its growth pattern has always intrigued me.. its leaders seem to grow 6 to 8 inches.. almost outside the dwarf definition ... but all its side branches are more dwarf ...

the reason i brought this up.. is someone said his was too bare .. to ugly for mass propagation ... and that simply isnt my experience with it.. its chubby ... so i suspect one or the other of us.. might not be talking about the same plant ... [he shall remain nameless...]

i got this plant in 2000 .. one of my first ... the pic is dated 2008 ... and i have no recollection of how big it was when i got it.. but i am sure it was one gal. ... and of no particular size ... it appears .... from camera angle.. that i was squatting down when i took the pic.. today it is no more than 5 feet ...

Well it certainly doesn't seem like the 'Adcock's Dwarf' I am growing. Maybe there is some variance in growing habit for this cultivar but what do I know. You don't suppose that's under stock free ranging inside that cultivar that was missed and left to grow. Maybe Edwin will chime in.

Mine is slow growing with dense foliage. I am lucky if I see 2 inches of growth a year.

I planted mine in 2000. A one gal. pot and about a foot tall. I am guessing 15 + years old now. Now 30 H 24 W.

Ken, it looks like a midwest interpretation of 'Adcock's Dwarf.' My notes show that it is a seedling selection named for Graham Adcock of England's Hillier Arboretum in the 1960s.

With the parvifloras I usually candle prune for size and shape. I am certainly learning as I am going and in the case of the Miyajima I let the candle that creates the central leader go a couple of years ago, because I wanted more height. unfortunately when you do that with a medium grower you get a 8" - 12" candle that creates a long bare area of trunk not concealed by needles. I prefer a tight form as opposed to the open kind of leggy look some of these pines would have if not pruned (for example, ogon-janome)I do this also due to the fact that I have a limited amount of space. So with the Miyajima I have a neck with a head on top, that I could just cut off, but instead I am trying to be patient and am letting some of the candles below the bare area be a little longer each year to cover up the bare spot. One thing to keep in mind is that when these trees get tighter they are more prone to fungus and need more attention to cleaning out dead needles. I learned that lesson the hard way when I lost a very old Azuma this year that I had been working on for several years and was very dense. But hey, it's as much about the journey as the result, right?

This is from Dennis Dodge: Many of the Pinus Parviflora that have been on this page that have non Japanese names such as : Pinus Parviflora Blue Lou Pinus Parviflora Betsy Pinus Parviflora Billie Pinus Parviflora Catherine Elizabeth Pinus Parviflora Dendo Pinus Parviflora Iona Pinus Parviflora Little Hedgehog Pinus Parviflora Lorraine Pinus Parviflora Nellie (After my mother ) Pinus Parviflora Smout Pinus Parviflora Karen These plants were introduced into the trade by a good friend and plantsman by the name of John Proudfoot from Scotland . These are only a very few great plants he has developed by cross pollinating Pines and growing them on for years to pick out the most dwarf and the bluest forms. These plants were rouged out of thousands of seedlings and grown for many years before naming . John has also introduced many Pinus Sylvestris and Pinus Pumila Dwarf's such as Pinus Sylvestris Denny Boy and Pinus Pumila Blue Note both of which are true garden gems. I have been most fortunate to have John as a friend and to be one of the first to introduce most of his plants to the US . .

Best Stock for grafting Pinus Parviflora
Q
Comments (28)
Hi Guys, Had a few minutes and thougth I would check out the forums. Thought this was an interesting conversation. In the US we are not likely to find Pinus armandii or Pinus koreansis, at least not at a reasonable cost. I normally put 3-5 needle on P. strobus and 1-2 needle on P. sylvestris. As a rule, most pines are compatable initially. It's the long term that is a problem. I have heard that P. mugo is a good rootstock for P. parviflora although I have never tried it. I have very few problems with P. strobus in pots. If you are having problems with too much water just don't water that often. I have some that have been in 1 gallon pots for well over 6-7 years and while the plant looks bad and is pot bound. As soon as you put it in the ground it grows like normal. I think P. strobus is a good choice in most cases in the US. This year I put P. ponderosa on P. strobus and I was fairly successful. P. rigida and P. contorta seem to be picky about the rootstock. I have a large P. virginiana on P. sylvestris and there is a hugh difference in size at the union. I imagine that there will be issues at some point. Bill

Abies koreana(nordmanniana?) 'Starker's Dwarf'
Q
Comments (9)
Edwin, thanks for all of this assistance. The 'Starker's Dwarf' cultivar I had always thought looked unusual for an Abies koreana but I did not really question it's Abies koreana designator for two reasons. First, it's widely distributed by Iseli Nursery, one of the most prominent, older nurseries in our country. See the link below. Also I have seen unusual leaf formations on other conifer cultivars(Pseudotsuga menziesii 'Fretsii' comes to mind), so I figured it was just an odd-needled form of Abies koreana. Much appreciation to both Clement and yourself for verifying what we had began to suspect. Clement had also posted a photo of Abies chensiensis and the needles looked very different from this form, almost sharp and more light green. More discussion is needed here as I'd love to know what this beauty is, both for future trading and proper labeling. Notes also made about Picea breweriana 'Wuestemeyer'. I appreciate the help Edwin and my database continues to be sharpened slowly like a knife thanks to your endless assistance. Your value to these forums is as great or greater then any other. Here is a link that might be useful: Iseli's offering of Abies koreana(actually nordmanniana) 'Starker's Dwarf'

that's how I roll, Ken. For the lion's share of my 600+ cultivar collection, I have noted the responsible human, along with the date and place of the discovery. For me, the story is just as important as the plant. Lacking the stories, they're all just a bunch of really peculiar trees, right?

I came across both growing habits of the 'Adcock's' Dwarf.
One like Dave's, which is a pretty globose one, but also one like Ken's, which is an upright form with several leaders and faster growing.
I don't know what happened in the past, maybe a faster growing mutation arose which also came in ciculation under the same cultivar name...

Dump it Ken! not 'Adcock's Dwarf' ... at least not anymore! :o)

Ken,

I have never touched mine.

It seem strange that one cultivar will have two different growing habits and still retain the same cultivar name.

Leave yours as is ..Looks good to me.

I am not sure what blue is referring too. Even Edwin calls it 'Adcock's' Dwarf'.

Edwin can call it what he likes Dave, it ain't Adcocks's Dwarf! if it ever was it's reverted so still isn't entitled to that name ..

I didn't say that I call both forms 'Adcock Dwarf'.
I said that I came across both forms under the same cultivar name...

could this be an understock issue???

a more vigorous understock making the scion into a more aggressive plant???

and no.. i have no clue what my understock is ...

and no again ... its one of my first.. beloved ... regardless of name or form ... it isnt going anywhere.. unless i decide its too big for the spot.. and i send a few pieces off for grafting.. and destroy this one ... though i doubt that will ever happen..

Stephen or Edwin,

Sorry for the confusion here.

I guess I will have to ask a simplistic question. I am almost afraid to ask or comment anymore but I feel safe with you.

If Ken cuts the reversion out, assuming that is what happened, could it still retain Adcock's Dwarf' cultivar name?

Is the one I am showing correct? I am thinking it is.

Ken and Dave,

It has nothing to do with the kind of understock which was used for this dwarf cultivar.
Imo a faster growing branch arose which was propagated and since then it started to live it's own life under the same name...

The same thing is happening with the Chamaecyparis obtusa 'Nana Gracilis' and Picea glauca var. albertiana 'Conica'.
In both cases faster growing branches were taken for propagation and the original dwarf form is slowly diasappaering...

Ken's specimen doesn't show a reversion which could be "helped" by cutting it out, no his whole plant is a reversion.

Dave, you're showing the true 'Adcock's Dwarf' here, which is a very nice specimen!

Please, never feel afraid to ask or comment something about conifers at this forum.
That's why this forum is for, there are specialist here in all kind of fields...

I've read several times that 'Adcock's Dwarf' isn't a realiable bushlike plant. Whether that is the original or seedling, I'm not sure.

Since I was on Bob's site recently I remember seeing this.

PINUS PARVIFLORA Ã¯Â¿Â½PYGMY YATSUBUSAÃ¯Â¿Â½

A congested, dwarf form with twisted foliage, it is similar to Ã¯Â¿Â½AdcockÃ¯Â¿Â½s DwarfÃ¯Â¿Â½ only it stays more reliably bushlike.

Yes Dave, yours is a nice specimen indeed, and ken keep yours by all means, you got the space to indulge yourself, where as I'm more or less full, so any excuse for me to move something out to make room for others ... and discovering I have a plant incorrectly named is all the motivation I need :o)
