A classic palm in the PNW. Windmill Palm or Trachys as they are also known are extremely popular. And they should be. Moderately fast growing palm to about 18′ tall in 10 years. The trunk is covered in fur and this acts almost like insulation to protect the interior meristem from cold. Very cold hardy to near short dips to 0ºF- many venerable and ancient Windmill Palms can be found in old neighborhoods having gone through the very worst winters of the last 50 or more years. The fronds usually have drooping filifers on the species but that can vary. Male and female and requires one of each for viable fruit set. Following huge aromatic cream colored flower structures pollinated berries drop and will often germinate in open ground. Full sun to full shade. Drought tolerant but regular irrigation in rich soil will speed growth. Excellent performance in tight spaces. Occasionally young palms become nitrogen starved and turn yellowish. To correct simply feed with all organic fertilizer and mulch and water well through summer.
Plants with Deer Resistance
There is nothing more frustrating than deer devouring your garden. Deer are a lot like people, they will try anything, especially if its new. So, while there are no plants that are 100% deer-proof here are some selections from our plant list that have proven to be less often on the menu. Of course a fence is always the best defense.
Tip: pay attention not just to the species but the genus as well. Though not 100% impervious, some are much less prone to consumption than others. Pay attention to what they don’t eat, for instance they seldom eat Digitalis therefore, it would be prudent to try other species of Digitalis rather than moving on to a completely different genus. You’d be surprised the choices that you have. To extend that line of thinking. Notice that deer seldom bother Boxwood, therefore it would be wise to try other plants in that family (Buxaceae). You might be surprised to find that Sarcococca and Pachysandra are both in that family and their deer resistance is good too. A few other families that share deer resistance are the Iris family (Iridaceae), Ferns (Dryopteraceae) and Daphne, (Thymelaceae). Remember that you don’t know if they will consume it unless you try and deer have tastes that not only vary they can also change.
If you don’t feel like springing for a fence and you insist that Bambi shine free I’ve had relatively good luck with 1cm x 1cm black bird netting, It can be stretched around tree trunks or posts to provide some measure of protection, and it is almost invisible from a distance. The downside is that deer can become tangled in it and UV seems to break it down. But as a temporary barrier it has merits.
More considerations:
Deer will seek out irrigated plants during the driest parts of the year (wouldn’t you?)
Newly installed plants are often more vulnerable. It’s a deer- it can’t tell the difference between your new favorite plant or an offering of food.
Deer will rut on plants, often small trees- they should be protected if vulnerable. Surround with sheep wire to 6’ tall. Rutting is to remove fur from their antlers and to leave their scent. Either way it really screws up trees when they rub off the bark and branches especially if the tree is very young.
Deer do what nature tells them to do- not to piss off gardeners- innovation and patience are your responsibility.
Climate Adapted Plants for Gardeners in the PNW
Trachycarpus fortunei var. wagnerianus
Waggies! Our fave hardy palm at Xera. The fronds on this slower growing tree are stiff and tidy and have none of the drooping filaments on the branch tips that the species T. fortunei possesses. To 12′ tall in 7 years. A very clean and tidy looking palm with a distinct asian look. The fronds are even finely outlined in white hairs…more definition for this stately plant. Grows about 2′-3′ a year if well watered. You really can’t water Trachycarpus too much in the ground, it just makes them grow faster. Same wooly trunk as the species. Waggies are recommended for windy cold areas as they are not affected by those conditions. Fantastic cold hardiness not suffering damage until temps dip below about 5ºF. This is a great palm for colder gardens and tolerates quite a bit of shade. Always looks it’s clean best.
Tulbaghia natalensis
Cute little perennial Society garlic with wonderfully sweet fragrant flowers, Best described as intense violets. To 10″ tall and forming expanding but diminutive clumps that are deciduous in hard freezes. Blooms May-August. Excellent for warm rock gardens or containers. Protect containers from temperatures below 20ºF. In the ground it has survived slightly below 10ºF in rich, well drained soil and full sun. Best in a warm position where you can catch a whiff of the wonderful soft lilac colored flowers. Wonderful and sweet cut flower. The foliage on this species lacks the pungency of the more common T. violacea. Moderate deer resistance. Light, consistent summer water. Mulch with leaves if extreme cold threatens. South Africa.
Tulbaghia violacea ‘Edinburgh’
Society garlic. This form of the popular South African perennial has performed fantastically in our garden. Aromatic clump forming foliage that rises to 10″ tall and to 2’wide in time. In June and continuously until frost spikes emerge, to 2′ and hold clumps of luminous, soft lavender flowers. Each spike is in bloom for a week or more. New flowers are continuously produced. Remove spent spikes to tidy. Full sun and WELL DRAINED rich soil with regular summer water. Very drought adapted when established. In cold gardens its best on hot slopes. Freezes to the ground in winter, returns quickly in mid spring. Foliage is intensely aromatic of garlic when disturbed. Useful, pretty, long blooming. Moderate deer resistance. This form was selected in Edinburgh, Scotland.
A very handsome version of one of our best native broadleaved evergreen shrubs . I spotted this form with larger leaves that are thicker and convex in the coast range of Douglas County. It gives the shrub a much more substantial appearance . The thick leaves emerge tinted salmon pink before settling to its permanent deep lusterous, dark green. To 6′ tall x 4′ wide in 6 years. Very dense habit is reminiscent of boxwood. This is a very useful and handsome form of Evergreen Huckleberry. This cutting propagated form will have a very uniform texture and habit. In late spring small pink to white urn shaped flower transform into deep black purple tasty fruits. Plant more than one shrub to increase pollination and fruit set. Rich soil high in humic content with regular water in summer. Mulch annually. Allow it to dry between watering. Plant on 3′ centers for a tidy fast hedge. Full sun to quite a bit of shade. Not bothered by deer. Almost formal appearance. Prune after flowering if needed. Oregon native plant.
Xera Plants Introduction
A form of evergreen Huckleberry that is found on the north and central Oregon coast. The leaves are slightly longer and curve a bit and have a fine but noticeable serration. This is a slightly bolder form that is very handsome and somewhat formal in appearance from the species. Forms a shrub with large canes that grow in earnest and then arch.. White flowers are slightly larger than normal and appear in spring form slightly larger than normal black sweet fruit, about the size of a caper. Plant more than one shrub to increase pollination and fruit set. Full sun to full shade in humus rich, highly organic soil . Mulch for the first several years. Irrigate to establish for the first year or two then it should have a large enough rootball to resist summer drought. Otherwise light summer irrigation speeds growth. New growth is salmon orange and turns to shades of yellow before settling to dark green. Very pretty native shrub that demands more irrigation and mulch in full sun. Makes a wonderful informal hedge in time. This form has a pronounced arching shape. Excellent hedge material as this is cutting propagated and will maintain a uniform habit. Wonderful form from the northern Oregon coast. To 8′ x 8′ in 10 years. Prune if needed in Autumn. Oregon native plant.
Xera Plants Introduction
Vancouveria hexandra
Inside-Out-Flower is a commonly seen terrestrial component in dry to moderately moist woodlands in our region. The duck foot shaped leaves are conspicuous and pretty and in late spring to mid-summer a continuous supply of dainty downward pointing white flowers. Spreads in gardens very well in enriched soil with regular summer water where it will quickly assume the role of an intertwining ground cover. Winter deciduous- un-like its close and much more drought adapted relative Vancouveria chrysantha (Yellow inside-out-flower, Siskiyou Vancouveria). This perennial is perfect for life among shrubs or mixing with other woodland perennials in part shade to shade. Adapts well to garden culture and thrives on regular summer irrigation. Locally native in the city of Portland. To 10″ tall and spreading. Some deer resistance. Oregon native plant.
Verbena rigida
Vigorous and floriferous perennial Verbena for tough areas. Spreading by underground stolons in rich to average well drained soil this deep purple flowering perennial covers ground in short order. Full sun and light summer water when established to lengthen bloom time. Even then it begins flowering in June and continue unabated for two months. To 2′ tall and 4′ wide. Give it room to spread and do not pair with delicate neighbors. Hellstrips, Insanely hot and dry south facing hillsides. Freezes to the ground in winter- returns from the ground when truly warm weather arrives. Moderately deer resistant. Water twice weekly to establish and once growing you can taper off. It is important to do this for the first season, un-established plants may not make it through winter.
Vitex agnus-castus ‘Sensational’
Excellent California selection of Chaste tree with thicker, bluer flowers. Large growing shrub with aromatic finely divided leaves in mid-July in PDX spires of blue flowers erupt from each branch tip. It remains in bloom for 3-4 weeks. And if you remove spent flowers more will appear. Full sun and poor to average well drained soil. No summer water when established. Attains tree-like status with great age. May be pruned back hard in spring to contain the ultimate size. Blooms on new wood. Long lived and hardy below 0ºF. Leaves appear late in spring- often not until mid-May. Be patient. Loved by pollinators and bumble bees specifically. A shrub in full bloom will be a haze of drunken bumbles who after a day of working will often fall asleep in the flowers of this shrub. Tolerates the hottest sites and is very long lived.
Watsonia latifolia
A very large flowered Watsonia and one of the hardiest of the genus. Wide green spikey leaves rise to 2′ tall in spring. In late spring to early summer 5′ tall spikes of tubular red opening to orange flowers line the stems. Loved by hummingbirds and cut flower aficionados alike. Rich soil in full sun in a protected position- a south or west facing wall is ideal. Freezes to the ground below 20ºF- re-sprouts in spring. Forms an expanding clump to several feet across. A fun genus to experiment with in our climate. Rated as zone 7 in its native high elevation South Africa. We think its more like 10ºF in our climate. Plant with royal red Lobelia tupa and Rosa ‘Bengal Fire’ for a red extravaganza. Excellent performance at the Oregon Coast. Somewhat deer resistant. Mulch for the first few years. Nearly evergreen for the first several years. Established clumps can go dormant with summeer drought. Resist the urge to remove these dead leaves until spring. It will resprout with spring warmth.
