Plants for privacy screens

Could you recommend some plants for a privacy screen that are also narrow? These would be planted in front of a fence in our backyard.

Here is some general information on plants for creating a screen.

Here is a list of narrow plants for a screen from local garden designer Chris
Pfeiffer: “Fastigiate shrubs for naturally narrow hedges.” Compiled by Chris
Pfeiffer. 2005.

Zones 5-6:

American arborvitae ‘Rheingold’ (Thuja occidentalis ‘Rheingold’) 5’h x
3’w

Barberry ‘Helmond Pillar’ (Berberis thunbergii f. atropurpurea
‘Helmond Pillar’) 6’h x 2’w

Boxwood ‘Graham Blandy’ (Buxus sempervirens ‘Graham Blandy’) 8’h x 1-1/2′
w

English yew ‘Standishii’ (Taxus baccata ‘Standishii’) 4’h x 1-1/2′ w

Irish yew (Taxus baccata ‘Fastigiata’) 20′ h x 4′ w

Japanese holly Jersey pinnacle (Ilex crenata ‘Jersey Pinnacle’) 6′ h x
4′ w

Japanese holly Mariesii (Ilex crenata ‘Mariesii’) 3′ h x 1-1/2′ w

Zones 7-9, in addition to the above:

Dwarf yeddo rhaphiolepis (Rhaphiolepis umbellata Gulf GreenTM) 3-4′ h x
2′ w

Heavenly bamboo ‘Gulf Stream’ (Nandina domestica ‘Gulf Stream’) 4′ h x 2′ w

Japanese euonymus ‘Green Spire’ (Euonymus japonicus ‘Green Spire’) 15′ h x
6′ w

You might also consider installing a trellis to increase the height of
the fence, and then growing an evergreen vine such as Clematis armandii,
evergreen hydrangea (Hydrangea seemanii), or star jasmine
(Trachelospermum jasminoides).

This link is also helpful (scroll down to
“Evergreen Vines” and look for appropriate height and light requirements).

You could grow bamboo, but I would recommend growing it in a container,
or a series of containers, as you do not want the roots to spread. I have
seen an effective bamboo screen between two houses growing in a long
rectangular lined wooden trough (lined with bamboo barrier). Some species
of bamboo are more tolerant of partial shade than others. Look for a
clumping, rather than a running, bamboo (like Fargesia) to be on the safe
side.

plants for narrow planting areas

I am redoing the narrow planting areas (2-3′ wide) on either
side of our 20′ long entry. Garages from next door townhouses butt up
against the outer edge on each side, causing morning sun and afternoon shade on one
side, and vice versa on the other side. I have picked out some
euphorbias, heucheras, and carexes which should do well. I’m wondering
if I should have some taller, more dramatic plants to offset these and if
you have any suggestions of ones which might work. Also, any bulb ideas
would be appreciated.

Have you considered putting up trellises on one or both sides? Then you
could grow vines which require little width, but still have the
advantage of height. You could also grow taller plants (maybe some
grasses like Miscanthus or even a well-restricted–using root
barrier–Bamboo) in containers, and keep them shaped to suit the narrow
space. Some shrubs and trees are naturally narrow or fastigiate in growth
habit.

Here is a list of narrow plants compiled by local garden designer Chris
Pfeiffer, c2005. Some will be too wide for your planting area, but you
might want to research those that fit the site.

American arborvitae ‘Rheingold’ (Thuja occidentalis ‘Rheingold’) 5’h x
3′ w

Barberry ‘Helmond Pillar’ (Berberis thunbergii f. atropurpurea ‘Helmond
Pillar’) 6’h x 2’w

Boxwood ‘Graham Blandy’ (Buxus sempervirens ‘Graham Blandy’) 8’h x 1-1/2’w

English yew ‘Standishii’ (Taxus baccata ‘Standishii’) 4’h x 1-1/2’w

Irish yew (Taxus baccata ‘Fastigiata’) 20’h x 4’w

Japanese holly Jersey pinnacle (Ilex crenata ‘Jersey Pinnacle’) 6’h x
4’w

Japanese holly Mariesii (Ilex crenata ‘Mariesii) 3’h x 1-1/2’w

Dwarf yeddo rhaphiolepis (Rhaphiolepis umbellata ‘Gulf Green’) 3-4’h x
2’w

Heavenly bamboo ‘Gulf Stream’ (Nandina domestica ‘Gulf Stream’) 4’h x 2’w

Japanese euonymus ‘Green Spire’ (Euonymus japonicus ‘Green Spire’) 15’h x
6’w

There are also a good number of tall perennials you might try, such as
(for your afternoon sunny side) Helenium, Verbascum, Baptisia,
Eupatorium, and bulbous plants like Allium and Eremurus, and for your
shadier morning sun side, Macleaya, Digitalis, Filipendula ulmaria,
Anemone x hybrida, Actaea (formerly called Cimicifuga), Lilium martagon, Thalictrum, and Veronicastrum.

There are many excellent gardening books you could consult for ideas.
Since you have a small, narrow space, I highly recommend local garden
writer Marty Wingate’s book, Big Ideas for Northwest Small Gardens
(Sasquatch Books, 2003). You are welcome to visit the Miller Library,
where you can do further research and also borrow books.

Buxus renovation pruning

To renovate old Buxus hedge, when is the best time to cut back to 15-30 cm shoots? It appears that new shoots are pushing through now. My American Horticulture Society Pruning and Training book suggests late spring, but that may not apply to Seattle.

I consulted a local organization, Plant Amnesty, and their information sheet on Buxus says that April is the best time to prune. It is important not to prune when it is either too cold (leaves will turn grey) or too hot (same result).

Peter McHoy’s book, A Practical Guide to Pruning, also says to do your renovation pruning in mid- to late spring, and further suggests that drastically reducing the height of the hedge should be done in stages, over two to three years.

shrubs and low trees that will grow in the shade

Can you suggest some shade shrubs/low trees that could be used in the bottom quarter of a huge, years-old pile of yardwaste and branches that is now a 20 foot cliff? I have started with some Vinca minor in the lower part but could use some ideas of some things to plant that might get 15 feet tall, evergreen, and grow in woods/shade or sun through trees.

The closest list I could find to meet your needs is one of evergreen shrubs that will grow in shade:

Japanese aucuba – Aucuba japonica vars.

common boxwood – Buxus sempervirens

camellia – Camellia sp.

gilt edge silverberry – Elaeagnus x ebbingei ‘Gilt Edge’

Euonymus – Euonymus fortunei radicans

Japanese aralia – Fatsia japonica

drooping Leucothoe – Leucothoe fontanesiana

Oregon grape – Mahonia aquifolium

Burmese mahonia – Mahonia lomariifolia

longleaf mahonia – Mahonia nervosa

holly leaf osmanthus – Osmanthus heterophyllus vars.

English laurel – Prunus laurocerasus ‘Mount Vernon’

Japanese skimmia – Skimmia japonica

evergreen huckleberry – Vaccinium ovatum

nannyberry – Viburnum lentago
