Dogwoods

Better general dogwood cropFew flowering trees are more beloved than the Dogwoods. Seeing one in full bloom - their branches covered with clouds of white (or occasionally, pink) flowers – makes you immediately start thinking about where you might have room for one in your yard!

The tree dogwoods we carry here at Shooting Star Nursery fall into three groups: Cornus florida, which is native to the eastern US; Cornus kousa, which is native to eastern Asia; and Cornus nuttallii, which is native to the forests of the Pacific Northwest.

One of the keys to keeping your dogwoods happy lies in understanding what their native habitat is like. In the wild, most types of dogwoods grow as understory trees; protected from the heat of afternoon sun. They also tend to prefer well-drained soils that are rich in organic materials. In general, Cornus florida and its cultivars prefer afternoon shade and a good layer of mulch to keep the roots cool and moist during the summer. Cornus kousa is more sun and heat tolerant than C. florida, and most of the best cultivars for the Rogue Valley have C. kousa as one of the parent species. While we rarely carry Cornus nuttallii, two of the largest-flowering dogwoods we carry have C. nuttallii as a parent.

Here are a few of the Dogwoods varieties Shooting Star carries regularly:

 

Cornus florida Cultivars:
Cherokee Brave: Flowers feature dark pink to reddish bracts that fade to white in the center. Red foliage in fall. 25’ tall by 20-25’ wide.

 

cornus florida rubra sm crop2Rubra: Another pink-flowered Dogwood, a softer shade of pink than Cherokee Brave. 20’ tall and wide.

 

  

Cornus kousa Cultivars:
Galilean: Creamy white floral bracts come to a point at the tip. Flowers are large, and are followed by bright red fruits in fall, which is much appreciated by birds like Robins and Cedar Waxwings! 20’ tall and wide.

 

Cornus kousa Milkyway 1000x1000Milky Way: Pure white, long-lasting flowers and abundant fall fruit. One of the smaller Dogwoods – generally 15’ by 15’.

 

 

Cornus Hybrids:
Celestial: A C. florida x C. kousa hybrid. Celestial is a sterile variety (no fruit) with white flowers that turn pink as they mature. 20’ by 20’. 

 

Eddies White WonderEddie’s White Wonder: A C. florida x C. nuttallii hybrid. Big white flowers - 3-4” across - on a large tree. To 40’ tall and wide.

Pinus nigra 'Oregon Green'

'Oregon Green' Austrian Pine

Oregon Green Pine crop smIf you love the look of Pines, but just don’t have the room for something like a 60’ tall Ponderosa, ‘Oregon Green’ Pine might just be the tree you’ve been waiting for.

'Oregon Green’ is a lovely conifer, with dense dark-green needles, an open branching structure, and a classic pyramidal shape. In the spring, branches are tipped with showy silvery-white ‘candles’ of new growth that darken as they mature.

Unlike most of the other pines you’re probably familiar with, ‘Oregon Green’ grows relatively slowly – maybe 1’/year – and gets about 15’ tall by 12’ wide at maturity. This makes it a great choice as both a focal plant in smaller yards, or as part of a privacy screen or windbreak.

Easy to grow, versatile, drought tolerant and deer resistant when established, and beloved as a nesting place for songbirds; ‘Oregon Green’ Pine packs a lot of great attributes into a compact and elegant tree!

Native Iris

Native Iris species

Iris innominata resizeHere in southern Oregon, we’re fortunate to have a nice selection of native Iris available for our gardens. While our native Iris lack the in-your-face showiness of their Bearded Iris relatives, they do have a lovely, refined look to them that many gardeners prefer. They’re also tough, sturdy plants that are both deer-resistant and relatively drought tolerant.

Native Iris do best in sunny to light-shade areas, and work beautifully in borders, or as part of a woodland garden. They bloom from March into late June (depending upon species) and only require occasional water during the summer months – because these plants are already adapted to our summer-dry Mediterranean climate. In addition, most species feature colorful ‘veins’ on the flowers that serve as nectar guides for bees and other pollinators.

The one requirement these plants do have is that they require well-drained soil. If your soil tends toward clay, plant them on a slight mound so excess water can drain away from their crowns quickly – or plant them in pots!

Here are a few species of native Iris that Shooting Star carries regularly:

 

Iris bracteata2Iris bracteata: Also known as Siskiyou Iris, this lovely plant is endemic to the Klamath-Siskiyou region of southern Oregon and northern California. Flowers are generally creamy white to pale yellow, with contrasting veins of a rich brownish-purple. Plants feature slender leaves, and grow between 6-12” tall. 

 

Iris chrysophylla2Iris chrysophylla: Another Iris from southern Oregon and Del Norte County, California. Iris chrysophylla is generally a pale yellow with contrasting purple veins. Plants range from 6”-2’ tall, and are easily distinguished from I. bracteata by their extremely long floral tube.  

Douglas Iris2Iris douglasiana: Named after Scottish botanist David Douglas, Iris douglasiana can vary widely in color – from nearly white with blue accents to a rich deep purple. They also prefer part-sun to full shade in the garden, and like water every 2 to 4 weeks during the summer months. If you have encountered a blue Iris while hiking along the coast, it was probably Douglas Iris! 

 

Iris tenax: Also known as Tough-Leafed Iris, ranging from southwest Washington to northern Oregon. In the wild, it is usually found along roadsides and in grasslands and forest openings. Flowers are generally lavender-blue in color, and plants grow in tight clumps – about 1-1/5’ tall. Unlike most other Iris, Tough-leafed Iris does not like to be divided.

 

Pac CoasrPacific Coast Hybrids: Pacific Coast Iris hybrids are the real showstoppers of the group. Flowers come in an incredible range of colors – blues, purples, reds, oranges, browns, and multicolors; often with showy ruffled petals. They’re also the fussiest of the bunch (but well worth the effort!): they don’t tolerate clay soils or watering during the heat of the day, and prefer not to be divided every year.

 

If you’d like to try creating your own native Iris hybrids, it’s easy to do – and a lot of fun. Since most of the Iris described above have similar cultural requirements, you can create mixed plantings of several species. Iris hybridize freely – just collect the seeds when they are ripe, grow them out, and see what exciting color variations you come up with!

Sarcococca

Fragrant Sweetbox

Sarcococca ruscifolia

Dark and shady places - like the north walls of a home - can be extremely challenging sites to plant. Sarcococca, or Sweetbox, is an ideal shrub for low-light situations like this. Thriving in everything from part sun to deep shade, Sweetbox is an attractive, broad-leafed evergreen with glossy dark green leaves that provides a good backdrop for airier ferns and flowering shade perennials. 

There are a handful of different species ranging from upright shrubs to slowly spreading groundcovers. They all have simple leathery leaves and are for the most part deer resistant, making this genus a true problem solver in a myriad of ways. Not to mention they bloom in late winter when most plants haven't even broken dormancy! 

Even though their small fringy flowers are not what you would consider showy, they amply make up for it with a powerfully sweet, vanilla-like fragrance that is sure to get attention. Add in red to black berries that lend a festive quality later in the year, and you've got a great four-season plant!

In return, this understated plant merely asks for moderately fertile soil with decent drainage and regular water throughout the hotter months. That is not to say Sweetbox wouldn't prefer rich, humusy and acidic soil, but it is quite adaptable once established. 

 Here are some of our favorite types:

Sarcococca confusa gets 3-5' tall and wide at maturity, with a moderat growth rate; perfect for a low hedge or evergreen border in a shade bed! It is such an easy, reliable shrub to grow that it has received an Award of Garden Merit from the Royal Horticultural Society.

Sarcococca ruscifolia or Fragrant Sweetbox is the largest of the more common species reaching 3-6' high and wide with an arching habit and more rounded leaves. It is known to naturally espalier itself against a house and thus can be useful in tight spots and under windows. Its growth is slow to moderate and can easily be kept at 3’.

Sarcococca 'Fragrant Valley' is a compact yet vigorous selection growing to 18-24" tall and 3-4' wide. 

Sarcococca 'Fragrant Mountain' attains a slightly larger size at 2-3' tall and 3-4' wide, making it a great alternative to Skimmia japonica. 

Sarcococca humilis (Dwarf Sweet Box) is the smallest member of the group, reaching just 1-2' tall and 8-12" tall at maturity. It's an elegant little shrub though, with slender, tapered, glossy dark-green leaves.

All of these varieties are disease resistant and tolerant of drier soils and less than ideal conditions. Sarcococca species are great supporting cast members for the shady garden (…we can't all be stars...) - and a must have for lovers of fragrant plants!

Ribes sanguineum 'King Edward'

'King Edward' Red Flowering Currant

Ribes King EdwardFlowering currants are one of the glories of the early Spring garden, with their cascades of brightly-colored flowers and soft green, scalloped leaves. And one of our very favorite flowering currants is Ribes sanguineum ‘King Edward’.

A cultivar of our native Ribes sanguineum, 'King Edward' has darker pink flowers than the native species, followed by dark blue berries in the summer. Both ‘King Edward’ and the native species are absolute magnets for hummingbirds and other pollinators. Later in the seasons, berry-loving songbirds like robins, thrushes, grosbeaks, cedar waxwings, etc., flock to the berries (which taste better to them than they do to humans, so we’re happy to share!).

Flowering currants will bloom heaviest when in full sun, but in hotter areas like the Rogue Valley, they also appreciate a bit of afternoon shade. In fact, they’re also a great choice for dry shade gardens or for planting under an oak or other large tree. ‘King Edward’ will grow in a variety of soils but does require good drainage; if you plant in clay, place it on a mound or along a slope. Being a native plant, they are used to dry summers and wet winters, and will do best if you can mimic those conditions in your garden.

'King Edward' grows quickly and has a lovely open habit that mixes well with other plants. They can get at least 4-5' tall and wide, and are also relatively drought tolerant once established.
