Wow !
laric decidula pendula it's better : Larix decidua "Pendula".
Picea abies "Cincinata" are doubtfull, normaly it's a tree, with little pendulous branch and long little twisted needles.
picea abies virata = Picea abies "Virgata"
Picea wilsonii are a tree, not a flat toped plant.
Your picea pungens "sweet roll "are 1 Abies balsamea,
Piea pungens "Staney's Gold" a very poor plant.,
Clement

David, first of all: thanks for showing us your nice pics with conifers and their first new growth.

Second: Clément is right, the comments he made are true.
I've some other comments to add as well:
-Picea abies 'Pendula' = Picea abies 'Reflexa'.

-Your Picea abies 'Virgata' isn't the true one.
This is because is does have too maney side branches and it's colour is blueish instead of green.
I think your's is a Picea abies 'Weeping Blue'.

-Your Pinus strobus 'Horstford Dwarf' is in reality a Picea glauca 'Alberta Globe'.

-It's better to stake that Picea pungens 'Stanley's Gold'.
It will give you a nice specimen in a couple of years!

Good luck and I hope I helped you with my info...

Clement my computer skills are not the greatest must have hit the wrong key,

from stanley&sons (Picea abies Virgata)called the snak-bark spruces. Very long stems with large green needles plant can grow 3ft ayear .we like this better than inversa as main stems go out and up all leaves hang down. the last time i showed this tree it was labled picea engelmannii snake.You said it was picea abies virgata so i change it.

(picea abies Cincinata) A small upright tree with pendulous branches leaves green . Plant grows abought 1 ft a year . Almost looks like it has shoulders.
(Picea pungens Sweet Roll) A dwarf green from of colorado spruce .This plant is part of jerry morris rocky mountain collection .leaves are green on a round rising bun . needles are the size as species.

(picea abies pendula) A weeping green norway spruce. Must be staked for height . Flowing green foilage makes a skirt on ground. Has hanging cones 4 inches long when it fruits.mine has 4inch cones.

Thanks for the comments.

Nice! I like the smithiana.
