Sept Sale Trees and Shrubs
The flowers start as small buds, opening to full petalled, wide open rosettes of a bright crimson-red. As the flowers age, the blooms becomes dome-shaped while the colour – unusually for the English Roses – gradually intensifies. It forms a very bushy, neatly rounded shrub with slightly arching growth. Named after the well-known writer, journalist and broadcaster.
David Austin Roses were not developed for Zone 3. BUT it is possible to have success here in Manitoba by following a few key tips.
Choose a location that is not in line with strong north winds
Plant the crown (this is where the roots end and the woody shrub begins) of your rose 6”-12” below the surface of the soil. As your shrub will be in full leaf at time of purchase clean off leaves that will get buried.
In the fall you will need to cover with a deep layer of mulch. Wood mulch, straw, leaves or a combination of all. Use a burlap tarp (Not Plastic) to cover and hold down with rocks or stakes. This will ensure the mulch is not blown away. A full wheelbarrow or more per rose is not out of the question. Throughout the winter direct your snow clearing efforts to cover your roses as well. The more insulation the better.
Don’t remove the tarp and mulch until night temperatures are consistently hovering about zero to +3 with no threat of deep freeze, as we sometimes see in April.
We hope you enjoy growing your David Austin Rose.
‘Roundabout’ is a compact, green garden orb. Perhaps its color is better described as viridian, a sort of bluish green. Whatever color you perceive, it is a super hardy, symmetrical addition to the garden, like a spherical topiary that never needs shearing. Slow growing with needles in perfect scale to its small size, ‘Roundabout’ is a winner for today’s smaller landscapes. Loves full sun and well drained soil. ‘Roundabout’ was discovered at Iseli Nursery as a witch’s broom growing on Picea pungens ‘Green Spire’.

Larix gmelinii ‘Romberg Park’ is a superb dwarf, deciduous conifer that will develop tufts of short branches giving it appeal in all seasons. In early spring, it is one of the first to push growth, programmed from its cold native habitat and short growing season to take full advantage of warming temperatures. The softly textured, light green needles change to yellow in fall, and then drop to reveal the plant’s many short stems for winter interest. Plant in light, well-drained soil in a sunny garden.

Delicate, green needles and short, slender branches give Larix decidua ‘Prag’ a soft, airy texture. Newer branches sweep gently upward and then spill down as they mature, giving ‘Prag’ a low, mounding form. Super cold hardy, this deciduous conifer is a great choice in some challenging garden conditions.

Larix decidua ‘Puli’ is an elegant alternative to the common L.d. ‘Pendula’. When staked, its slender branches create a narrow silhouette that is more dense and lighter green than ‘Pendula’. If unstaked, ‘Puli’ branches spread out slowly along the ground and make an effective ground-cover. Very attractive in gardens with an Asian aesthetic.

Pinus sylvestris ‘Hillside Creeper’ is a classy creeper that spreads out and forms a flat mesa of layered branches that are covered with thick, green needles. The vigorous, hardy pine, lighter green in winter, makes an excellent ground-covering option for banks or walls or tucked in and around boulders. Found as a seedling by Layne Ziegenfus of Hillside Gardens, Lehighton, Pennsylvania.

For longer needles, a more natural, open look and a consistent habit, the versatile Pinus mugo ‘Palouse’ is perfect for a casual landscape where a larger Mugo Pine is warranted. The robust green selection grows into a bushy, rounded mound, or with annual candle pruning, it can be kept smaller and more refined. A reliable and hardy addition to the sunny mixed border, it also works well as a divider or to fill a corner.
