I'm propagating (10) cuttings of it right now. Don't know "jack" about its winter color.

From the other day at Bickelhaupt (October) and color was not bright at all:

Thanks for the picture. That's bright enough if it holds through the winter. Did you wake up to snow this morning?

6-8 inches.

Just had a little breakfast and had my first Chevy small pickup experience.

Books tend to call it 'Holmstrup Yellow'.

One of my favorite yellow foliaged arbs is George Peabody. For me, it has never bronzed out, as most such cultivars are prone to do permanently sometime before Christmas of the first winter.

I have seen some bronzing on it, usually when the temps dipped to the -50 F area, before windchill. Other than that, it has held color exceptionally well.

I've not experienced the golden version of Holmstrup in my yard, and based on how G.P. is doing, I'm not likely to try. I don't mean to dampen your enthusiasm, it's merely the subjective exerience I have aquired in the frozen tundra.

Thuja ÂYellow HolmstrupÂ, purchased as rooted cuttings in 2004 from a wholesaler in Minn. Pictures were taken today.

The George Peabody arborvitae is T. occidentalis 'Lutea'. An old (origin before 1870) cultivar dating back to when some cultivars were sold as botanical entities (lutea instead of 'Lutea', in this instance). As is often the case when a cultivar has been around a long time, more than one clone has been sold. Not all plants acquired as 'Lutea' will necessarily have matching characteristics.

"Over the years, nurseries have selected improved sports and kept selling them under the original name, or under slight variants (e.g., T. occidentalis lutea 'Bobbink & Atkins' and T. occidentalis lutea 'Mary Corey')"

--Jacobson, NORTH AMERICAN LANDSCAPE TREES (Ten Speed Press)

Thanks for the additional replies -

I've seen Lutea/George Peabody and it is a larger, wider plant than I'm wanting to grow, whereas the yellow version of Holmstrup would fit my space better. Looks like I'm about to order a flat of rooted cuttings.
Thanks again folks

Holmstrup's Yellow is correct not Yellow Holmstrup. for reference there is a picture in Adrian Blooms Gardening with Conifers, page 171 with Adrian pruning what must be a plant 20yrs+, looks to be around 15ftx10ft in size.
Bluespruce.

I've got 'Holmstrup's Yellow' as being correct also. (Erhardt - List of Conifer Names, 2005); A.M. Jensen 1951.

Starterdude - Looks like with good care and some food, a plant can get going rather quickly (I'll bite and assume you're fertilizing them for future stock plants).

Am I right?

Dax

Dax,

I'll probably keep half for stock plants and grow the rest on for retail.

Frank

Frank, I'd like to be your next customer when ever you decide to sell.

Marshall, I already got some guaranteed 1-gallon presents for you come spring.

(Did a double Stanley order the other day)

As usual, nice stuff Frank.

Dax

Frank,
Me, too. If you ever decide to sell by mail order, I'd love to purchase a 'Holmstrup's Yellow' from you.
Thanks,
Mike

So far it seems the most prevalent combination outside of commercial listings is 'Holmstrup Yellow'. However, in addition to reference cited in above post Welch & Haddow (World Checklist of Conifers) spell it 'Holmstrup's Yellow'. I do not know which is correct. The ideal way to check would be to track down the publication where the name was first presented in what is considered a 'valid' way (by the author of the name). Otherwise, a reference giving what is known to be the first validly published spelling would be adequate. One of both of those mentioned here using 'Holmstrup's Yellow' may have determined the original spelling.

Of course (naturally), Bickelhaupt Arboretum spells it:
'Holmstrup Yellow'.

Dax

Hmm,

this looks like an interesting plant. Is it supposed to be a yellow sport of 'Holmstrup' or a completely different plant?

Thanks in advance,
Ernie

Yes. Krussmann, MANUAL OF CULTIVATED CONIFERS (Timber Press) says "Mutation of 'Holmstrup' with yellow foliage."

If it is a mutation, it has an entirely different habbit than Holmstrup.
Bluespruce.

Bickelhaupt's sign said (seedling origin).

Habit variants pop out of arborvitaes as well. I have seen at least two on 'Fastigiata' myself. Maybe 'Holmstrup Yellow' is both a habit variant and a foliage color variant.

Hopefully it holds heavy snowloads well unlike 'Sunkist' which always seems to be this big, huge, wide "thing" in collections.

Then again, Adrian Bloom's plant I would expect to be a single leader - but maybe the guy doesn't think like I do.

Got a ton of 'Hetz Wintergreen' sown. I'm hoping I get some interesting stuff. Seed collected at Bickelhaupt.
