Longwood Gardens. June 2005. While these lovlies are technically f. glauca they are not as frosty and silver as the best of that forma. There are
frostier examples on the same grounds up the road (see photos below) for example. They are good representatives of the species or at very least
intermediate between f. atlantica and f. glauca. The photo on the left shows decent specimens but they are much larger than are first glimpsed from
down the road or when scrambling through the Longwood Pinetum lawn. Look at the trunk, which strangely enough has lichens more glaucous
than the foliage, and you'll appreciate the real age we have here.

Cedrus atlantica 'Albospica'
lc: new growth pure white
or: Europe before 1868

Cedrus atlantica 'Argentea Fastigiata'
ha: narrowly pyramidal
lc: grey-green
in, or: Hillier Nurseries 1956, more widely sold after 1961
ns: Jacobsen (1996) thinks this is similar to or a rename of 'Glauca Fastigiata'.

Cedrus atlantica 'Aurea'
ha: pyramidal
ll: shorter than species typical
lc: golden-yellow, especially in spring
or: Boskoop, Netherlands before 1900

Cedrus atlantica 'Aurea Robusta'
ha: pyramidal, more vigorous than older 'Aurea'
ll: larger than older 'Aurea'
lc: yellow, a lighter shade than 'Aurea', some blue tones occur if shaded
in: denOUden & Son Nurseries, Boskoop, Netherlands 1932 

Cedrus atlantica 'Contorta'
ha: semi-dwarf, contorted, upright
lc: glaucous blue

'Fastigiata' ('Columnaris', 'Columnaris Erecta') - click image
Gotelli Collection, US National Arboretum. Spring 2004. Several decades has made this plant just more narrow and not really fastigiate. The color remains bright at the tips.

'Fastigiata' ('Columnaris', 'Columnaris Erecta') - click image
Lewis Ginter Botanical Garden, Richmond VA USA. Summer 2003. A young 'Fastigiata' in it's more curious spiky phase. It's certainly a choice for a third of the specie's footprint
but we think most people would prefer the powder blue of a good 'Glauca'.

Cedrus atlantica 'Fastigiata' ('Columnaris', 'Columnaris Erecta')
ht: 70 ft. tall x 6-10 ft. wide, some plants prove much wider
ha: columnar, laterals very short, older plants more narrowly pyramidal to ovoid and often quite fine-textured and a bit spiky.
lc: blue-green, not usually as silvery or blue as most 'Glauca' today, the older growth being more dark and green. It tends to be a bicolor of blue and green when plants are vigorous with
lc: ample portions of both recent and older needles. Some older plants without much blue new tissue are much more green.
or: Lalande, Nantes, France before 1890 - the same folks known for Pyracantha coccinea 'Lalandei'

f. glauca - click image
Longwood Gardens. June 2005. These century plus mammoths are rich frosty silver-blue and amongst the finest
seen anywhere in the US. The problem with new, grand estates is that one has to wait 150 years to get scenary
this grand.

f. glauca - click image
Administration Building, US National Arboretum. June 2005. This is far from the largest blue atlas in the Americas but
like real estate there is a good bit of profitability giving to location and neighborhood value. This beauty sits outside the
main USNA building in a courtyard and it situated in a very nice spot.

f. glauca - click image
Bonsai Pavillion, US National Arboretum. June 2005. An grand, super blue cedar does not require a huge lawn and
a quarter acre of admiring space. Note how the black glazed pot brings out the dark, contrasting bark. There are
bonsai experts who favor the true cedars for their projects. Get to a forum or nursery who can help you and
good things are a few years and a few cubic feet away.

 

 

 

Cedrus atlantica f. glauca ('Glauca') - click image

 

Cedrus atlantica f. glauca 'Glauca' (f. argentea Murr., Glauca Group)
lc: more intensely, glaucous blue, usually silvery-blue in gardens
or: occurs in the wild and is a genetic range occuring in seedbeds and nature both.
ns: the RHS use Glauca Group but as it occurs in the wild, we prefer the botanical forma.

'Glauca Fastigiata'? - click image
Tyler Arboretum. June 2005. This plant was labeled as 'Glauca' (columnar form) and may perhaps belong to this
cultiva or at least a very similar concept - narrow erect and bluer than 'Fastigiata'. It surely must be one of the
largest one's in the eastern US. The plant is a tad more blue than the usual 'Fastigiata' and we could not possibly
assign it there. In any event, one is well advised to propagate this superior Tyler tree for its remains dense and
narrow and quite dense for many decades.

Cedrus atlantica f. glauca 'Glauca Fastigiata' ('Glauca Victoria')
ha: narrowly pyramidal, branches erect and upswept at times
lc: rich powder blue as the better 'Glauca' and far bluer than regular 'Fastigiata'
or: US trade since 1931 per Jacobsen (1996)
lsp: Jacobsen records a 92 foot tree in Everett WA USA

'Glauca Pendula' - click image
Gotelli Collection, US National Arboretum. Spring 2003 and June 2005 (from different angles).

Cedrus atlantica f. glauca 'Glauca Pendula'
ha: broadly weeping, forming irregular and spreading mounds. Plants are often trained to
ha: form the now famous "living waterfall". Plants are often trained over and around arbors or some
ha: very ornately arranged combinations of stakes and bamboo. We've even seen plants trained in shapes
ha: that are best described as resembling a grazing blue woolly mammoth. In some more affluent US
ha: neighborhoods it has been popular (as least with their designers and architects) to place a single specimen
ha: on the sprawling front lawn as a statement or status symbol.
lc: rich glaucous, silvery-blue
or: Paillet, Chatenay, France before 1900

Cedrus atlantica 'Granny Louise'
ha: upright, very columnar

Cedrus atlantica 'Pyramidalis'
