more frost and freezes: minimizing damage

Living and working in northwestern Oregon, garden designer Wesley Younie is no stranger to dealing with challenging environments. When presented with this garden’s elevation changes, drainage management, and extreme climate conditions, he devised a plan that addresses it all—along with a specific functional wish list from the homeowners. Want to know which plants he used? Here are the plant IDs for this beautiful, sustainable landscape.

While flowering trees are what you want, drought tolerant trees are what you need. Fortunately, there are a number of drought resistant flowering trees that will adorn your garden while requiring minimal water. These types of plants can form the bones of a water wise landscape.

This species of plants originate in central China. The closely related species R. molle japonicum come from Japan. Both these deciduous varieties are relatives of the popular Ghent and Knapp Hill hybrids.

Ornamental Japanese Maples are widely available for planting in your garden. The autumn colouring makes these trees spectacular when planted en mass in a woodland or Japanese garden setting.

You only need subtle shade changes to achieve a striking effect with well chosen plants. Good companions complement one another in a range of ways.

Arduaine Garden in Scotland is well-known in international Rhododendron circles for the number of wonderful species grown here, many of which are considered tender elsewhere and grow unusually under a canopy of mature Japanese larch. To some people, rhododendrons are those unpleasant purple-flowered objects which clog up our native woodlands. This is but one species, Rhododendron ponticum or a hybrid of it which spreads rapidly both by seed and sucker. Arduaine’s collection is extensive containing about 400 distinct species. The rhododendrons range from the large-leaved giants such as Rhododendron protistum, Rhododendron sinogrande and Rhododendron macabeanum to the small-leaved, high altitude plants which are often classed as rock plants, a sample of which would include Rhododendron fastigiatum, impeditum and orthocladum. In between these two extremes sit the majority of species of differing sizes with a variety of foliage shapes and an astonishing range of flower colour and form. One of the specialities is the only Rhododendron from Ceylon – Rhododendron arboreum subsp. zeylanicum.

Arisaema sikokianum is a herbaceous perennial plant with vertically patterned  flowers.

Modern tea gardens may seem to be a contradiction but since the 15th century the wabi tea ceremony has influenced the tea gardens purpose and design. Originally when tea plants (Camellia sensi) were introduced into Japan from China in the 6th century they were the prerogative of the ruling classes and used expensive ingredients and equipment.

Holland Park has some Zen like features but fails my Zen test. The classic elements of a successful Zen are stone, sand or gravel, water, plants and space. Then there is a question of balance between yin and yang. Cramped or cluttered gardens inhibit the flow of spirit so space is potentially the key ingredient of a Zen garden.

I will use Shangri-la as an all encompassing name for spiritually based gardens and areas of harmonious natural beauty stealing a name from James Hilton in his novel Lost Horizon.

At the heart of the Judas tree is an ornamental flowering tree with rich, pink to red, pea shaped flowers in May followed by long pods.

My name is John Rohde. My garden is located 15 miles north of Baltimore in Towson, Maryland, in Zone 7b. This is the second full year for this pandemic garden. I enjoy mixing annuals and perennials with trees and tropicals in containers. There is a water feature, tubs of lotus, a patio, and a vegetable garden at the rear of my house.
