Vanderwold's Pyramid Limber Pine

vanderwolf_pine

The 'Vanderwolf' Pine has proven itself a good conifer choice for a hot, dry spot; that won't get too large and has soft, two-toned needles.  This western North American native Pine can tolerate our dry, hot summers and wet winters.  Well draining soil, including dry, rocky hillsides, will help it tolerate those conditions even better.  We have especially been attracted to it because it doesn't have the scratchy quality of most conifers, you can get close to it and enjoy the blue and green needles.  The 'Vanderwolf' has a more open habit than some other sheared looking conifers when young but gets denser with age and can be used as an effective screen, a specimen position, or looks great in groups of three.  'Vanderwolf' is more pyramidal than the species- Pinus flexilis.  It is difficult to pin down a mature size on the 'Vanderwolf' but it is slower growing so it is useful in smaller spaces.  It can get 20-25' tall and 10-15' wide but it seems to get taller more quickly than it gets wide.   Like most pines, it only needs occasional watering once established and this variety is more disease and pest resistant than some other pine species.   Also like most pines, it is deer resistant.

Vitex agnus-castus

Chaste tree

vitex-plant-of-the-week

Our hot summers allow us to enjoy this Mediterranean native that is drought tolerant and deer resistant.  Heat is neccessary for profuse blooms, and profuse it is once it gets going in July and August.  The blooms slowly open from the base to the tips eventually reaching up to 12 inches long and last at least 4 to 5 weeks.  The color can vary from pale lavender to a darker purple and attract bees and hummingbirds from far and wide.  The fragrant leaves are very attractive on their own- they are divided similar to a laceleaf Japanese Maple and are a very pleasant shade of soft blue-green and gray-green underneath.  Chaste tree is late to leaf out in the spring, helping it avoid damage from our late spring frosts; but makes a good small shade tree in the heat of summer.  One of the fun things about Vitex is that you can grow it into whatever form you like, multi-trunk or single trunk tree or a large, broad shrub.   We have seen older specimens around the valley that are 10' tall by about 12-15' wide, meaning they are cold hardy once established and can get quite large.  However, they can be maintained at 6' tall and wide or trained up as a small shade tree. They take very well to a severe pruning, even all the way back to the ground if needed.  We have also seen them be used successfully in large containers against hot walls and parking lots.  Vitex grow slower with drought conditions and grow fairly rapidly with regular water and richer soil but will tolerate both conditions well.   We have been very impressed with the cold hardiness and drought tolerance of these shrubs as well as their many uses.  Vitex are one of the few choices for a small tree or large shrub that thrives in the heat and have lovely blooms late in the season.  

Caryopteris x clandonensis 'Dark Knight'

Dark Knight Bluebeard

caryopteris-closeup-plant-o

This late summer bloomer goes by several common names, Bluebeard, Blue Spirea, or Blue Mist so we usually stick to calling it Caryopteris. It is indispensible for an easy, deer resistant, drought tolerant (but also tolerant of moist soils), and long blooming addition to your garden border. The plant in the photo is 'Dark Knight' which is a darker shade of periwinkle-blue from the common 'Blue Mist' variety. Both varieties put on a show with hundreds of flowers from July to frost, attracting honeybees and butterflies from all around. A low maintenance plant, Caryopteris can be kept at 2-3' tall and wide with a spring pruning but will get larger if left unpruned. We find that our winters do some tip pruning anyways so it is best to clean them up in spring when you see new leaves emerge and pruning right above them, which can sometimes be as low as 6" from the base. They quickly recover into a nice mounded shape, looking dense and uniform. So they are great for the maintenance person that loves to come in and hedge trim everything! With its aromatic, lance shaped leaves, this shrub has proven to be deer resistant. The leaves have a blue/silver tinge that look great with other silvers like Artemesia or contrast with purple foliage like smokebush. We find Caryopteris to be drought tolerant because of its very deep taproot but can look lusher with regular water in well draining soil. Full sun is best and they will tolerate reflected heat.

Agave neomexicana

Hardy Agave

Hardy Agaves capture us like no other plant.  Their almost mathematical geometry is mesmerizing and they are tough as nails.  One of the true survivors on our property- managing the dips in temp to 0 degrees Fahrenheit in 2013 and the foot of snow in 2017 with not a speck of damage.  The two main hardy Agaves that we enjoy growing are Agave parryi which is a bit more pinecone shaped and Agave neomexicana which is a bit more open.  They both are blue in tone and have decorative, but nasty thorns.  They require sharp drainage and seem to do best planted in a mound.  We amend the soil with 1/4" gravel or larger decomposed granite and use it for a mulch as well to keep soil away from the crown of the plant.  Agaves do best in full sun and can look striking in a container.  They require little water once established, their fleshy roots are good at growing deeply into the soil.  One sharp poke to the nose and deer will know to leave these desert plants alone.  These two species are hardy to at least zone 7, if not zone 6.  Once they get into the 2' wide range there is the possibility of them making a flower spike and then dying, but they have usually made pups by then which will carry on the Agave torch.  You'll want to make room for these gems in your drought tolerant garden.

Ilex meserveae 'Blue Girl'

Blue Girl Holly

photoIlexBlueGirl250x376

Holly may seem a bit pedestrian of a choice for a plant of the week, but it fits the season and the red berries brighten up these gray fall days. Plus 'Blue Girl' Holly is deer resistant (although in Ashland, the deer are ignoring this advice), drought tolerant, tough, and can tolerate sun or shade.  The glossy dark green leaves do have spines but they are not as sharp as many other holly types or even barberry.  The leaves look fresh and clean and are complimented by purple stems and bright clusters of red berries.  You can keep this holly around 3'-4' if you like with occasional pruning or let it get 5-6' tall and 3-6' wide for a dense hedge.  You do need a  'Blue Boy' to keep the berry production up, but it seems that there is usually a holly bush in the neighborhood to assist with pollination.   This species is especially cold hardy and can handle clay soils, appreciating the typically acidic ph of clay soils.  Keep watering to the drier side of the spectrum, and prune back if needed in the winter.   'Blue Girl' Holly is not a fast grower so it is suitable in a container paired with other festive-colored plants, like Heuchera, Nandina, and ornamental grasses.
