Abelia (Linnaea) mosanensis

Fragrant hardy Abelia is just that- not only is it ultra cold hardy, it possesses as far as we can surmise, the best fragrance of an already fragrant genus and basically a spot on redux of citrus blossom sweetness. A long procession of pink buds that open in clusters to powerfully fragrant white flowers. The fragrance carries for quite a distance on the summer air. Blooms June-Sept. Full sun to very light shade in rich soil with regular summer water. Not entirely drought adapted pair with other summer water cohorts. Forms a vase shaped twiggy deciduous shrub to 4′ x 4′ in time. Blooms on wood from the previous season prune after flowering if needed. Usually pruning is limited to tired non blooming wood which is self evident.  Cold hardy to below -20ºF Fall color is often dark red with pink tints and often lacking  Beware this shrub if drought stressed goes straight to crispy. Establish well before  setting it free. One of the most fantastic floral fragrances. Deciduous shrubs are not a hot category for several reasons but the fragrance of this ultra hardy shrub should be enjoyed everywhere. Delicious flower fragrance.

Abutilon (Callianthe) ‘Nabob’

Odd name for a wonderful flowering maple. This Abutilon has earned its fame with large deep red/black red pendant flowers for months on end. In one season it will form a substantial sub-shrub and bloom continuously as it grows.  Rounded habit to 4’x 3′. Its best home is in containers where you can inspect the intensity of the flower color up close. Each globe shaped flower is 1 1/2″ wide and they occur in a huge display for months. Loved by hummingbirds and pollinators as well. Rich soil with regular irrigation. In spring if the winter has been normal to mild it will often resprout from the base when warm weather returns. Mulch in autumn to protect the base. The early spring appearance is pretty awful the solution  is to water, water, water, and add a 1/2 cup of all purpose organic fertilizer. Recovery is rapid as the weather warms. If in a mobile container it may be moved into an unheated garage and watered once a month through winter. Bring out, fertilize and water when all threat of frost has passed. Classic flowering maple.

Abutilon (Callianthe) megapotamicum (a) ‘Red’

Everything about this form of hardy flowering maple is identical  to the species except the molten red flowers with deeper veins shot through. The 2″ pendant flowers appear from May to October on a large growing sub-shrub. To 6′ in a single season It makes rapid growth as temperature rise above 70ºF. Full sun, in a protected location in rich soil with regular summer irrigation. Abutilons look absolutely horrific in spring even after a normal winter. Expect this. The solution is to water, water, water especially as the temperatures rise. It blooms on new wood and flowers are continuous as the shrub grows. Mostly deciduous but it can be evergreen at the coast or in protected places in mild winters. Loved  by hummingbirds who are lured by the lurid red flowers filled with nectar. Cut back by 1/2 after all danger of frost has passed. Supply a handful of all organic fertilizer and water faithfully. Excellent performance at the Oregon coast. Inland it is best with the protection of a shrub covering its roots so that the soil does not freeze. In this situations it can live even thrive for many many years. Mulch with compost. Native to the mountains of Brazil. Root hardy to about 10ºF. Long lithe stems can be woven through a fence or a lattice.

This is a very handsome and dependable hardy Agapanthus bred in Ireland.  It forms a spreading clump and in mid summer 3′ tall stems support multiple pendant midnight blue flowers.. Full sun and rich soil. Add a handful of lime to the planting hole. Our soils are acidic and this perennial likes neutral (7) Alkaline (sweet) soils to perform at its best. You can also plant it next to a concrete sidewalk which will also give it the alkalinity that is craves. The clump of scrappy mid green leaves is shorter than most varieties and maintains a tidy plant both before and AFTER bloom so it makes an exemplary garden and landscape perennial. Regular water is crucial through the bloom period, July /August when flowering ends and you cut away the dead stalks it remains good looking until it totally disappears in mid autumn. Irish and UK Agapanthus appear to have much greater cold tolerance than American selections,  they wait to emerge until all threat of a freeze has passed. Very cold hardy easy to grow wonderful pendant tower of cobalt blue. The truss of flowers is very large and showy. Good cut flower, loved by pollinators too. Limited quantities. One of the finest lily of the niles for our gardens.

Agastache ‘Berry Princess’

We believe this to be a cross inheriting some of the coloration of A. auranticus as well as A. cana. To 28″ tall this clump forming, everblooming perennial brings bright red buds that open to purple flowers. The colorful combination lasts all summer into autumn. New flowers are born on the same spikes so do not remove. Moderate consistent water through the first summer to establish. Double dig soil to incorporate oxygen into the soil and aid in irrigation to the roots. Established plants get by with a little less. Loved by hummers and  pretty decent cutfower as well. Full all day sun for best performance, will not be quite as floriferous in part shade. Sweetly scented foliage is an extra benefit. To 18″ wide and slowly increasing. Excellent on berms as well as slopes. Mulch in fall.  Small rosette of winter foliage is protected by the previous years defunct stems. Prune these away after all threat of a hard freeze has passed.

Aloiampelos (Aloe) striatula

We’ve grown a lot of Aloes with purported cold and wet hardiness and this is the one that has been the most successful. A large succulent shrubby plant with rosettes of deep green succulent foliage. In late summer to autumn a showy display of large yellow flower spikes can occur. Very pretty and loved by all nectar seeking folks. Give this South African perennial VERY GOOD DRAINAGE in full sun and a warm position.  A slope is always helpful. Amend the soil with plenty of gravel and sand as well as compost- these guys do need to eat- so a little handful of organic fertilizer is recommended. Capable of freezing to the ground (below 15ºF) and resprouting from the base when truly warm weather arrives. Plant on a south or west facing slope preferably against a warm wall or boulder for added reflected heat. Easy, if large, container plant that you should protect from temperatures in the teens. To 3′ x 3′ on average in our climate. Mostly evergreen here. Combine with Agave, Cactus which will also increase their growth rate if you provide light, consistent water during hot weather.

Anchusa azurea 'Dropmore'

Anchusa azurea ‘Dropmore’

Alkanet, Italian Bugloss- neither name is very appealing but I’m here to testify that if you are a connoisseur of the color blue this big showy perennial is for you. To 4′ tall multiple spikes bear rich, deep, true blue flowers in one bodacious cloud. This form is not only a superior blue, but its a more reliable perennial. Most live 2-3 years but this often persists for longer. This borage forms a basal rosette of rough leaves- this is important to identify the inevitable seedlings- they are dark, dark green and spiny. Blooms first year from seed. A Spectacular plant for a young garden, a dry garden, wild border or in its most classic home the cottage garden. Full sun and average to enriched soil that drains quickly. Light consistent water to establish then drought adapted. Long, long blooming plant that often has bumble bees fast asleep in the cup shaped flowers. Very cool. Obvious pollinator gem. Very climate adapted plant.

Anemone nemorosa 'Alba Plena'

Anemone nemorosa ‘Alba Plena’

Excellently climate adapted, there are many forms of Anemone nemorosa but this is by far our favorite. Pure white flowers with a congested bunch of petals in the center. Natures pin cushion. Blooms late March to early May. Spreads  to form large colonies in rich well-drained soil with ample irrigation. The whole plant goes completely dormant by summer, cleanly disappearing before you have time to notice it. Part shade to full sun. Not bothered by pests or animals. Even though it goes summer dormant it’s still beneficial for these plants to receive regular water. You’ll notice the difference the following spring.
