Western Redcedar

T plicataThuja plicata, commonly known as Western Redcedar, is native to the Pacific Northwest and a is a popular, sturdy, and graceful evergreen frequently used in tall hedges or as a privacy screen. 

Quinault Lake RedcedarSouthwest Oregon is near the most southern edge of Western Redcedar’s range, which extends north into Washington and British Columbia. The largest Redcedars in the world are true forest giants, and can be found in the rainforests of the Olympic Peninsula, where several trees near 200’ tall by 60’ wide have been found.

Because the climate here in the Rogue Valley is hotter and drier that that of the Olympic Peninsula, plants here will generally get about 50-70’ all and 15-25’ wide at maturity, if left untrimmed.

T plicata 2Western Red Cedars look great when left in their natural shape, but they also respond extremely well to shearing or pruning. They grow at a moderate rate – roughly between 15-24”/year - and are generally pest and disease resistant. They’re also very pollinator-friendly, and serve as host plants for dozens of native butterflies and moths. Once established, Western Redcedar is relatively drought tolerant, and will generally only require deep watering once or twice a month.

As a group, Thujas of multiple species are widely used as hedges and privacy screens. They’re all easy to grow, relatively fast growing, have nice densely pyramidal shapes, and are tolerant of clay soils as long as the soils aren’t soggy. You will want to cage them to protect them from deer when they are young, but they grow quickly enough that you'll only likely going to need to do this for the first few years.

Thuja emerald greenShooting Star Nursery carries several different kinds of Thuja in large pots and as ball & burlap plants: Western Redcedar (T. plicata), Virescens and Excelsa - T. plicata cultivars, Green Giant and Virginian - hybrids of a cross between T. plicata and T. standishii (Japanese Arborvitae), and Emerald Green - a T. occidentalis (Northern White Cedar) cultivar. See the table below for more information. 

Fun fact: One of the common names for Thuja is Arborvitae (Latin for Tree of Life). Early French settlers to North America gave it that name when they encountered an east coast Thuja species (T. occidentalis), and learned from Native Americans in the region of the many uses the plant had: decay-resistant wood for building canoes and houses, sturdy fibrous bark used for clothing and cording, and roots and leaves with a variety of medicinal purposes.

Large Conifers

on Thursday, 09 December 2021. Posted in Winter Interest, Conifer, Deer Resistant

Full-sized Conifers: For Christmas and Beyond!

This week, we're going to talk about the big guys: iconic conifers that will reach over 60' tall at maturity. Most of these conifers are also fast-growing. There's something pretty magical about seeing a big healthy conifer in your yard and thinking back to the year you planted it as a small living Christmas tree. If you've got the room, we highly recommend these beauties - and they're all native to the west coast; four out of the five listed here can be found growing wild in Oregon!

 

PonderosaPonderosa Pine: Ponderosas are the classic pine here in southwest Oregon. They're stately-looking trees with dark green needles and dark, flaky bark. The biggest Ponderosa Pine in the state (268' tall) can be found growing in the Big Pine Campground, northwest of Grants Pass. Ponderosa Pines growing in your yard won't get that tall, but you can expect them to easily reach 60' to 100'.

 

Incense CedarIncense Cedar: Incense Cedars get their name from their wonderfully aromatic bark. They're lovely trees with rich green needles and reddish bark, and will happily grow in drier sites than most of the other trees mentioned here. They will probably reach a height of 60' - 70' when grown in your yard, but can get much larger in the wild. One of the largest Incense Cedars in the world - the Tanner Lakes Titan - is from right here in Jackson County, and is over 137', with an amazing dbh (diameter at breast height) of 12.8'!

  

Douglas fir coneDouglas-fir: Douglas-fir is the Oregon State Tree and is named for pioneering botanist David Douglas. Almost everyone is familiar with them as cut Christmas trees, so rather than include a photo of the tree itself, this photo shows the distinctive cones. They'll reach 80' to 100+' in the home landscape. Visitors to the Oregon Caves Big Tree trail have had a chance to see a 600-800 year-old Douglas-fir with the widest girth in the state.

  

Giant SequoiaGiant Sequoia: This is the only plant on the list that isn't native to Oregon, but they do grow well here. The biggest Giant Sequoia on the planet is the General Sherman Tree in Sequoia National Forest, which is around 275' tall, with a 100' crown. In the home garden, expect a mature height of about 100'. Young trees are fast growing, and have a densely pyramidal shape with soft-looking bluish green needles. 

 

 Coast RedwoodCoast Redwood: Anyone who has ever driven along Highway 199 to the coast is familiar with these majestic trees. Coast Redwoods require a bit more water than the other trees listed here (think of the climate they grow in!), and will do especially well if planted along a creek or near a pond. Your tree will likely reach 100' or so tall at maturity. The biggest Coast Redwood in the world is 'Hyperion' - which grows in Redwood National and State Parks in Del Norte County. It measures a stunning 397' tall, making it the tallest tree in the world!

  

Shooting Star Nursery regularly carries all these trees, albeit in much smaller sizes than listed above! If you like the idea of planting a tree as a living legacy, this might just be the year to plant one of these beautiful conifers. 

Compact Conifers

on Thursday, 09 December 2021. Posted in Winter Interest, Conifer, Deer Resistant

A Selection of Dwarf and Compact Conifers

Compact conifers - which range in size from 6' to 20' tall - are the perfect-sized plant for a small to mid-sized yard. They're large enough to make a statement but are a much more manageable size than large conifers, which can reach heights of 60-80' tall!

As we mentioned in our last Plant of the Week article, compact conifers never really stop growing - it's just that most of them grow fairly slowly and will remain small for a long time. The sizes given in the plant descriptions below are a good representative of their likely size in 10-20 years. Here are a some of our favorite compact conifers:

Dwarf Alberta Spruce smDwarf Alberta Spruce: A dark green, columnar spruce. They are relatively slow growing (around 6"/year), and will reach 10 to 12’ tall by 4’ to 5’ wide in 10 years  

Tannenbaum

'Tannenbaum' Pine: 'Tannenbaum' is a taller variety of the popular Mugo Pine. They are dark green, with a dense pyramidal shape. Plants are moderate growing (6' to 12'/year) and will be approximately 10- 15’ tall by 6-12’ wide in 10 years.

  

Silberlocke Fir detail'Horstmann's Silberlocke' Fir: This is such a showy little fir! 'Horstmann's Silberlocke' features upcurved needles with a white underside (see photo to the left).  Plants have a moderate growth habit (generally 6" to 12"/year), and will be around 12’ by 8’,  in 10 years.

 

 Black Hills Spruce sm

'Black Hills' Spruce: ‘Black Hills’ Spruce is more heat tolerant than most other spruce, and has a nice greenish-blue color. They’re slow growing (generally less that 6”/year, and will reach 15-20’ tall by 10-15’ wide in 10 years. 

 

 Oregon Green Pine ed'Oregon Green' Pine: A lovely deep, rich green pine with a moderate growth rate (6-12”/year); likely reaching 18-20’ tall by 15’ wide in 10 years.  

  Picea pungens Hoopsi sm

'Hoopsi' Blue Spruce: ‘Hoopsi’ is the very bluest of blue spruces! Plants grow around 6-12”/year, and will generally be about 25’ tall by 15’ wide at maturity.

Dwarf and Compact Conifers

A Selection of Dwarf and Compact Conifers

We get a lot of requests for dwarf (under 6' tall) and compact (6' to 20' tall) conifers, and this is a great time of year to find a good selection of them here at Shooting Star Nursery!

Let's start with a word about conifer sizes. Like most conifers, these dwarf and compact conifers never really stop growing - it's just that most of them grow fairly slowly and will remain small for a long time. The sizes given in the plant descriptions below are a good representative of their likely size in 10-20 years. Here are a few of our favorite dwarf and compact conifer species:

Picea glauca Procumbens smProstrate Colorado Blue Spruce: A sweet, prostrate form of Colorado Blue Spruce (shown here with Wilma Goldcrest Cypress in the background. These plants will do well in the garden, or in a large containter, and respond well to selective pruning and shaping. Size: 2' tall by 5'-8' wide in 10 years.

  

Hornbrook Pine smHornbrook Pine: A lovely little dark green, dwarf pine; this variety started out as a 'witch's broom' on a standard Austrian Black Pine. They are medium growing (6 to 12"/year), and will reach 3-6' tall and wide in 10 years.

  

Divinely Blue cedar sm'Divinely Blue' Deodar Cedar: Do you love the graceful branches of Deodar Cedars, but can't find the room to accomodate an 80' tall tree? Consider this dwarf form! 'Divinely Blue' has the same blue-green needles of the full-sized Deodar Cedar, but forms a low mounding shape with nodding branch tips. Plants are slow-growing (less than 6"/year), and will measure roughly 2-6' by 3-6' in 10 years.

 

 

Chalet pine detail sm'Swiss Chalet' Stone Pine: This is a very showy and decorative-looking little pine. One of the things that makes it special is that its dark green needles have a white reverse side, which really makes tha plant "pop" in the garden. 'Swiss Chalet' has a moderate growth rate (6-12"/year), and will be 5-8' tall by 2-4' wide in 10 years. While 'Swiss Chalet' can tolerate full sun, it will look even better if you can provide it with a bit of afternoon shade.

 

 Fat Albert sm'Fat Albert' Blue Spruce: This tree is pretty much everything you have ever wanted in a Blue Spruce, and is one of our favorits here at Shooting Star! It's also a wonderful choice for a living Christmas tree. The needles are a lovely shade of blue-green, and ttrees have a chubby, densely pyramidal shape (hence the name). 'Fat Albert' is a fairly fast grower - often over 12"/year - and can reach sizes of 25' by 15' at maturity.

  

The Blues'The Blues' Weeping Blue Spruce: If you are looking for a truly striking specimen conifer that can provide a strong focal point in your garden, 'The Blues' Weeping Blue Spruce is a great choice. 'The Blues' has an irregular, weeping form - and no two plants are alike. They respond well to creating pruning and shaping, as you can see from the three shown to the right. Plants are relatively slow growing - generally around 6"/year, and will reach 6-8' tall by 2-4' wide in 10 years.

Calocedrus decurrens

Incense Cedar

Calocedrus with fruit

If you have room for even one large conifer in your yard, Incense Cedar (Calocedrus decurrens) would top our list of recommendations!

Incense Cedars are native to the West coast; ranging all the way from northern Baja California up into central Oregon and western Nevada. Unlike many of the popular conifers frequently planted here in the Rogue Valley, Incense Cedar is heat and drought tolerant, and is tolerant of both clay and serpentine soils.

They get their common name from their wonderfully spicy-smelling, aromatic bark. Plants feature flattened sprays of rich green needles, with a rich reddish-brown bark that becomes deeply furrowed with age.

Calocedrus decurrensYoung trees are dense, symmetrical, and pyramid-shaped which – happily – also makes them an excellent choice for a living Christmas tree.

tanner lakes titanIncense Cedars generally grow at a moderate rate (1-2’/year) and will probably reach a height of 60' - 70' when grown in your yard. Wild trees can get much bigger though. In fact, one of the largest Incense Cedars in the world - the Tanner Lakes Titan - is from right here in Jackson County, and is over 137' tall, with an amazing dbh (diameter at breast height) of 12.8'!

Fun fact: the genus name Calocedrus comes from the Greek words kalos meaning beautiful and cedrus meaning cedar tree!
