ROCK GARDEN AND RARE PLANT LIST

 

                       The purpose of this list of “Companion Plants” is to provide you with the structural

                       and filler plants to bring year-around beauty to your garden.     

 

                       Each season has its special charm.  Cyclamen and trillium are first to appear in

                       very early spring followed by perennials and shrubs throughout the summer.

 

                       Bright and blazing fall color then ushers the garden into winter where the texture

                       of conifers and evergreen shrubs against the bare bones of deciduous trees

                       give promise of the coming of spring again.

SHORTIA:  Shortia are one of our most popular plants.  They are attractive through all seasons, having glossy, deep green leaves that often turn red in fall and winter, in addition to the early spring flowers, white or pink and ruffled.

The literature about their culture stresses that they grow best in areas with cool, damp summers, in neutral to acid soil, humus-rich and well drained. In Portland, Oregon our summers tend to be mostly dry with often low humidity, 20 to 30%, and extended periods of 80ºF occasionally in the 90ºs F. Night temperatures are much lower. Our established clump of Shortia galacifolia is thriving with a south west exposure under tall conifers which give some dappled shade. We do provide our woodland landscape with a nightly 20 minute micro-mist. We use no fertilizer except in the sales growing area where all of the plants get two or three applications of 1/4 strength 20-20-20 each spring into summer.

                DWARF SHRUBS   
Includes creeping sub-shrubs

(
Ericaceae is a word you will see after the name of many of the shrubs and dwarf shrubs in this list.  The following paragraph is an attempt to explain the word).

The family Ericaceae ( the heath family) are mostly plants that thrive in acid soils comprising about 125 genera and 3,500 species.  Many of the Ericaceae live in temperate climates, such as; azaleas, cranberry, blueberry, heath, heather, huckleberry, and rhododendron. The family also contains many tropical species.  The Ericaceae family consists of shrubs, herbs, and trees with leaves that are usually alternate. The leaves are simple and alternate or sometimes opposite or whorled. The flowers are bisexual. The flowers show considerable variability. There is a calyx orffour or five sepals joined at the base. The flower has four or five petals, usually joined to form a tube or trumpet. There are usually twice as many stamens as petals, and they are not attached to the corolla. There is a single style. The flowers are usually in clusters or spikes, but may be solitary.  The petals are often fused with shapes ranging from narrowly tubular to funnel-form or widely bowl-shaped.

AGAPETES: (Ericaceae)

A small group of evergreen, mostly epiphytic shrubs, usually distinguished by a visibly swollen rootstock.  Their range extends from the E. Himalayas through SW China and Indochina to SE Asia. The majority of species are closely related to the SE Asian - Malesian species of Vaccinium (huckleberry/blueberry family).  (Species of Agapetes from New Guinea and the SW Pacific are now placed in the Paphia genus). 

Agapetes are valued especially for their pendant flowers, usually red and rarely white or yellow, solid colors or with darker chevron horizontal bands.  The flowers mostly hang from the underside of the arching stems.  In borderline climates the hanging branches make a beautiful basket plant which can be sheltered in cold weather.  We had a very big plant die back to the swollen rootstock (caudex), but then it made a quick comeback that spring.  Cold hardiness is listed as +15F (Zone 8b) but we like to protect ours a little.

 

  Agapetes buxifolium.  Collected around 1855 on the border between Assam and Bhutan.  An arching plant to three feet, suitable for a hanging basket, or in the ground in acid compost.  The hanging flowers are red flaring sharply at the end of the long corolla tube.  The fruit is a fleshy white berry.  MB $9.50 and TB @ $12.50

NOTE, the whole Menziesia genus has been moved into Rhododendron.  Because there already was a Rhododendron ciliicalyx, this plant had to have a new species name.  It was named after Dr. Ben Hall at the U of Washington in Seattle.  Dr. Hall runs the lab that has done much of the genetic work on Rhododendrons.  Dr. Hall has also been very generous to the Rhododendron Species Foundation over the years. 

 

VACCINIUM: [all are in the Ericaceae family]  A large genus of over 450 species, evergreen and deciduous shrubs and small trees distributed world wide from near the Arctic Circle into the tropical and neo-tropical regions. There are many species native to S. America and the tropical islands of the S. Pacific including three species native to Hawaii. The commercial, culinary and medical importance of these plants is well known, but it wasn't until the late 1990s that the ornamental value of many of the Vacciniums became truly appreciated. Many are still not available in any significant numbers but we are doing what we can to propagate and promote some of the best. The genus vaccinium is usually found growing in acidic soils, either sandy or peaty, humus-rich. They can be used horticulturally in woodland settings, rock gardens, partially shaded borders and as container plants which suits them very well.  One reference book says that only one species is not edible. 

We obtained much of our information from an excellent book:  'Blueberries, Cranberries and other Vacciniums' by Jennifer Trehane, published in association with the Royal Horticulture Society as part of their Plant Collectors Guide Series and Timber Press.  Also from Hillier's and Beans excellent reference books.

SYRINGA: Lilac  These magnificent flowering shrubs or trees are delightful additions to our gardens during their blooming period.  Lilacs make great border plants while several of the more compact types, if planted in containers, can be placed where their rich fragrance is more readily enjoyed.  As a group they prefer well-drained, near neutral soils, although acid soil is tolerated.  To maintain the best shape and a succession of vigorous, flower-producing shoots, prune out some of the older branches after blooming and remove the current year's spent flowers. 

Syringa patula var. kamibayshii.  (Nakai) K. Kim (Lilac). This lovely variety of the species patula - the Manchurian Lilac, grows into a tall graceful shrub with arching branches.  Richly colored clusters of small fragrant blossoms appear in late May, in various shades of lavender-pink.  As with all lilacs, pruning of old flowering wood should be done immediately after flowering to maintain a desirable size and shape.  (We could not have given you the correct name of this species without the help of Freek Vrugtman, Curator Emeritus of the Royal Botanical Gardens, Hamilton, Ontario, Canada).        Z3-8/S      Gal $10.00


Trochodendron aralioides.  (Wheel Tree), bush form.  Selected by Polly Hill. This native to Japan, Taiwan and Korea is sometimes found growing as an epiphyte on Cryptomeria tree trunks, but usually can be seen as a tree, 60 to 80 feet tall in the wild.  In cultivation 20 to 30 feet is more common.  The form listed here has stayed at 3 to 4 feet for us and makes a striking specimen in a tub.  Its spirally arranged leathery leaves are bright apple-green with scalloped margins.  Its common name "Wheel Tree" comes from the way the stamens radiate from the center of the flower like the spokes of a wheel.   Z6-10/S-pt    TB  $13.00     Gal  $15.00
