'Blonde Ambition' Blue Grama Grass

Bouteloua gracilis 'Blonde Ambition'

 

This little North American native prairie grass is a true performer.  Many ornamental grasses don't start blooming until late summer, but this variety of Blue Grama Grass, produces it's blonde, eyebrow-like blooms in the early summer and persist into winter.   It also performs well in various garden locations, from clay to a more well draining or sandy soil.  At a super useful size of 2-1/2'-3' tall to 3' wide, you can use it on masse or as a single specimen to contrast with flowering perennials.   Everyone who comes into the nursery notices it, because of it's unusual horizontal bloom and that it always looks good.    It is very cold hardy, to Zone 4. and is drought tolerant but can also handle regular watering.  Like most ornamtental grasses it's fine textured, gray-green foliage is deer resistant.  We like to leave it up all winter as the stiff stems can hold up to snow and provide interest and texture in the winter garden.  In mid spring, when you see new growth emerging you can cut back the old stems to about 3" above the soil line and scratch out any old growth.   Bouteloua is also reported to tolerate being near Walnut trees, where most plants cannot thrive.

 

Osmanthus heterophyllus 'Rotundifolius'

Rounded Hollyleaf Osmanthus (False Holly)

osmanthus_rotundifolia

This evergreen shrub is being highlighted because it looks good all year round. No leaf spot, no diseases or weird pests, no old brown leaves, just glossy, thick leaves that start out light green and darken to a beautiful holly-like blue green.  The Holly Tea Olive or Rounded Hollyleaf Osmanthus is very easy to grow and seems to be happy in any location.  We have one planted on the east, west, and north sides of buildings and all seem to be thriving.  It may not be the first choice for a hot spot against a south wall but they seem to acclimate to where they are placed and will even tolerate clay soil.  They will be more drought tolerant in a shadier location but our established ones are rudely ignored and haven't complained.  A thick mulch layer will help any evergreen shrub, or any plant for that matter, retain moisture and withstand the changes in temperature.  This Osmanthus is hardy to Zone 6 and has shown no winter damage through Rogue Valley winters.  Like most Osmanthus it produces small, white, fragrant flowers, typically in the fall.  This variety will get about 4'x4' but can be pruned a bit tighter.  It is not fast growing but puts on steady growth each year and won't overrun it's location.  It is a great foundation plant or background for showier perennials. If the spines of Hollies are not your favorite this could be a good substitute since the rounded leaves only have slight spines- nothing to cause damage to the pruning gardener.   It can be deer resistant once established since it has thick, leathery leaves.  But in heavy deer country it can have a hard time getting settled if the deer constantly eat the new growth.  So cage it until it can get big enough to withstand the occasional deer browsing or test it out first- it seems to depend on the deer population on this one.

Sarcococca spp.

Fragrant Sweetbox

Sarcococca ruscifolia

Dark and shady places such as the north walls of a home can be challenging sites to plant.  Sarcococca is an ideal shrub for lowlight situations like these.  Thriving in everything from part sun to deep shade, Sweetbox is an attractive and glossy broad-leaf evergreen providing a good backdrop for airier ferns and 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 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 fragrance that is sure to get attention.  Add red to black berries that lend a festive quality later in the year and you've got a 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. 

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.   It's growth is slow to moderate and can easily be kept at 3’.  Sarcococca hookeriana v. humilis has narrower, more elongated leaves and spreads slowly by stolons from 4-8' wide with stems reaching 18" tall.  Also called Himalayan Sweetbox, it is a great companion under trees or at the base of more colorful deciduous shrubs due to it's colonizing nature and tolerance of root competition.  There are a few newer hybrids of this Himalayan species that bridge the gap between the two aforementioned Sarcococcas.  'Fragrant Valley' is a compact yet vigorous selection growing to 18-24" tall and 3-4' wide.  'Fragrant Mountain' attains a slightly larger size at 2-3' tall and 3-4' wide, making it a great alternative to Skimmia japonica.  Both cultivars 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.

Pinus thunbergii 'Thunderhead'

Thunderhead Dwarf Japanese Black Pine

thunderhead-pine-plant-of-t

'Thunderhead' Japanese Black Pine is a wonderful compact specimen conifer.  Like most pines it is drought tolerant and deer resistant but what sets it apart from other pines is it's tight, dense form and handsome white candles in spring that stand out from the dark green needles.  It is a slow to medium grower ranging from 5-10' tall and 5-8' wide but keeps it's dense form over time.  This Japanese Black Pine will tolerate drier, sandy soils or moister soil as long as it's well drained and requires full sun. They look striking in trios or as a specimen in a smaller garden.  Makes a great pairing with the white bark of birches, or yellow Spirea 'Ogon', or purple Smokebush.

Geranium x cantabrigiense 'Biokovo'

'Biokovo' Hardy Geranium (Cranesbill)

geranium-biokovo

This versatile and easy hardy geranium is a great choice for an evergreen perennial that is deer resistant, drought tolerant in part shade, and even gets fall color.  When looking for deer resistant plants it's always imortant to seek out scented plants, especially leaves with a strong smell.  'Biokovo' Geranium is one of the rare perennials to have a strong, spicy scent that is not Meditteranean or needing lots of sun. It performs best in a cool location with morning sun or at least protection from the hottest part of the day.  The broad, lobed leaves provide striking contrast to finer leafed perennials and grasses. 'Biokovo' spreads by rhizomes to make a nice spreading mound about 6-10" tall and 2-3' wide and can be a bit aggressive so make sure it's neighbors can hold its own.  Dainty, pale pink to white flowers with pink stamens emerge in late spring through summer, but this perennial remains interesting all year.  The variety 'Cambridge Blue' is similar except with a lavender-blue flower.  We usually have at least 10 or so varieties of hardy Geranium in stock, great tough, long-blooming perennials!
