Choosing the Right Shrub Rose
With the 2007 planting season soon to start, now is the time to start planning out any new shrub beds/borders to be installed this year. Or perhaps you have a too well established shrub bed that is in need of renovation. What better plants to use than shrub roses? As long as the space has good sunlight (3/4 of the day or more) then roses can successfully be grown and will provide some awesome color.
With so many shrub roses on the market it can be confusing which selections to use. What choice you make will depend on flower color desired, height considerations for your space & disease/hardiness issues for the area of the United Stated in which you reside.
Here at Johnson’s Nursery we offer shrub roses that are hardy for our climatic conditions and have good disease resistance. Hardiness is a relative term as some roses are fully hardy for our winters, yet others can be fully root hardy but sometimes suffer winter injury to the tops. Roses in this latter category are still considered hardy for our climate as the damaged portion can be pruned off in spring and the plant will push new growth from the roots. By late June they are fully recovered and blooming well. The key is to be patient and they will come back nicely.
A good example of this would be ‘Chuckles’ rose. I have Chuckles in my yard as it is one of my favorites. They are in a foundation planting along the west side of my house. Most years they have some tip-die back over the winter, but last spring mine were dead to the ground. After cutting the canes off at ground level, they eventually pushed new growth from the roots. By mid June they were so beautiful in bloom that I could not resist taking photos.
Here is a listing of roses we have for 2007 to help in your landscape planning:
This is a red climbing rose developed in Canada. It is completely top hardy and grows about 6’ tall.

These roses are fully top hardy in our climate.

Flower Carpet Roses:
These are a series. We carry them in Coral, Pink, Red, White and Yellow. Extremely low growing (2’) with very glossy foliage. Great repeat bloomer. While very beautiful, they are best used in somewhat protected sites (foundation plantings along south or east side of heated buildings).
An extremely disease resistant rose with bright raspberry red flowers. Great repeat bloomer. This rose can have winter die back.
From same breeder as Knockout. Has pink flowers.
A wonderful red rose. See previous article posted for full details. Red flowers.
Pink single-petaled flowers. Extremely floriferous to the extent that sometimes it seems like the plant is entirely covered with flowers so that no leaves are visible. Excellent repeat bloomer growing 3’-4’ tall. May have occasional winter dieback.
From the Parkland Series developed in Canada. Very pointed buds that open to a large pink flower that darkens with age. 3’ tall.
We also have a few rose varieties that are relatively new on the market and are “new” for us this year. Sunrise Sunset is supposed to get about 3’ tall with pink flowers that have an orange/yellow center. Yellow Brick Road is listed as a deep yellow shrub rose also growing 3’ tall. And the last one is Yellow Submarine which has yellow flowers fading to white. It is reported to have an upright growth habit. It is always a pleasure to test new varieties and see how they will perform under our conditions.
