'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!

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.

Goji Berry

gojiBerry2Also known as 'Wolfberry', the Goji Berry is widely recognized as a superfood - with high nutrient and anti-oxidant properties - makes a great addition to your edible landscape. Both the bright orange-red berries and shiny, oval green leaves are edible with an appealing spicy, nutty flavor. The leaves are traditionally enjoyed as a tea, and the berries can be used as a tea or for snacking, baking, or preserving.

Goji berry is self-fruitful, producing small, purple-pink flowers in late spring/early summer that are highly attractive to the bees. It can take up to two years to bear fruit which will be loved by the birds and other browsing animals. Harvest the small, oval, bright orange-red fruit from summer through fall by shaking each branch so the ripe berries fall onto a large basket or bowl. Avoid touching them to avoid oxidizing the skin which turns them black. It's best to enjoy them fresh, frozen, or dried after washing, or refrigerate the berries unwashed for up to two weeks.

gojiBerryThis is a vigorously growing, thorny bush with woody stems and should be seasonally maintained to keep suckers that grow from the base in check. Luckily, they are well adapted for growing in containers. Deer will be attracted to the edible leaves and berries, but this might be one situation where they could be a welcome helper.

Once established, goji berries are heat tolerant and drought tolerant. They perform best when planted in full sun, (with mid-afternoon shade during the high heat of summer), out of the wind, and in well-draining, neutral to slightly alkaline soil. They can grow 8-12 feet tall and wide at full maturity and can be easily pruned to any desired size.

Arbutus unedo 'Compacta'

Compact Strawberry Tree

arbutus-unedo-plant-of-the-

Compact Strawberry Tree is one of our favorites for so many reasons: it can tolerate sun or shade, is drought tolerant, provides fall flowers for the hummingbirds, has long lasting, spectacularly colored fruit and wonderfully shaggy bark - and it's also evergreen!

You can easily see how this relative of our native Madrone and Manzanitas gets its common name of Strawberry Tree. The orange and red fruits resemble strawberries, and although the fruit is technically edible, they are more for suited wildlife as they are bland and mealy in texture (Fun fact: the species name unedo is a combination of the Latin words unum meaning "one" and edo meaning "eat" resulting in "I eat only one", in reference to the technically edible, but distinctly untasty fruit!).

Arbutus medThe honey scented, pinkish-white, urn-shaped flowers can appear from fall into early spring and the fruits often come on at the same time or not long after. As with many other fruiting shrubs, some years seem to have heavier fruit set than others - but the fruits are so decorative and long lasting that they don't qualify as messy. With leathery, dark green, oblong leaves, reddish new stems and shaggy auburn bark it is handsome all year.

Compact Strawberry Tree is not the fastest growing evergreen shrub, but it will grow steadily to 5-7' tall and wide (eventually larger). With annual pruning it can be kept tighter and smaller. This is one of those rare plants that is happy in sun or part shade making it a great choice for a hedge with varied conditions. It is also tolerant of various climates and soils.

Arbutus2 treeLooking for something a bit taller, but with all the same great attributes as the Compact Strawberry Tree? The full-sized species - Arbutus unedo - gets about 10-15’ tall and wide at maturity. In its native habitat (Britain and the Mediterranean), Arbutus unedo usually grows as a multitrunked plant, but we also carry single-trunked specimens which make a really lovely small tree.

Arbutus flower and fruitWe have some planted on the north side of our house that have done wonderfully with no supplemental water after their first year and even survived the 7-degree winter with no damage! In extreme cold they will show some damage; so best to plant where they are not completely exposed to cold winds. The winter of 2013, where we got to zero degrees for several nights, proved fatal to some Arbutus and some rebounded after suffering damage on top.

Arbutus unedo 'Compacta' is great in foundation plantings or hedges. You will be hard-pressed to find an evergreen shrub with more year-round interest - plus the hummingbirds will thank you for providing a much-needed winter nectar source!
