Where do you buy your roses?

Roses can be bought anywhere if you know what to look for. Roses can be mail ordered, bought over the internet, or purchased in local nurseries and stores. Most mail order or internet suppliers sell very good quality bushes and will ship them to you at the proper time for planting. They also usually come with good planting instructions. Most suppliers are very good if you have problems with your order. The number of varieties available is usually greater than local suppliers. 

If you buy your roses locally in a nursery or store, be sure they are healthy. Early in the season (late March or April in this area) roses are sold bagged or in boxes. These are fine to purchase when they arrive fresh. The bagged roses are very hard to keep watered and tend to dry out after a few weeks. This is not good and will not lead to success with new rose. After they are in the store and the weather warms the buds begin to grow. This is also not desirable, avoid these plants. The roots in most of these bagged or boxed roses are short and will not support a lot of new growth that has already sprouted. These types of roses should be plant before the new growth has started. Also if the rose canes are brown, black and or shriveled, do not purchase them, they are dead or dying. Usually around May, potted roses appear in the stores or nurseries. These are usually more expensive because of growing and shipping cost, but you can see the blooms and foliage on these bushes. Look for nice healthy green plants with lush foliage and no signs of disease or pests.

You can have success with your new roses if you start with plants and give them good care. If you have questions regarding suppliers, varieties, or cultural practices, feel free to call one of our Consulting Rosarians listed on the home page under the Consulting Rosarians heading. They are knowledgeable growers who have volunteered to assist others in growing good roses.

Where to buy roses

There are many sources to buy new roses. I will list ones that I am familiar with or have had recommendations on.

 Pickering Nurseries (pickeringnurseries.com)-This is my favorite source for large roses, as they are grown on multiflora rootstock, have a great website, good prices, and are very customer friendly. I have had excellent experiences.
Hortico Nurseries (hortico.com)-They have a good informative website, grow on multiflora, and have a large selection. I personally have not had good results with ordering from them and have heard others having problems, but have also heard good reports about them.
Edmunds Roses (eroses.com)-I have been happy with the quality of the plants and service.
Wisconsin Roses (wiroses.com)- The newest exhibition varieties are available here on multiflora as maidens(newly budded that haven’t been growing in the fields). Order early for the best selection. I have only heard good reviews on them.
Almost Heaven Roses (almostheavenroses.com) Newer varieties available as own-root. Good quality, some harder to find and Vernon Rickard’s own varieties, good service have been my experience. Order for spring delivery as own roots are greenhouse grown like miniatures and will not like our weather if they arrive too early.
Roses Unlimited (rosesunlimitedownroot.com)- Also own root with hard to find varieties. Have heard very good reports.
Heirloom Roses (heirloomroses.com)- Also own root with hard to find and John Clement’s own varieties.
Ashdown Roses (ashdownroses.com)- Old Garden and landscape own root roses. Have heard only good reports.
Wayside Gardens (waysidegardens.com)- Good supplier.
Sequoia Nurseries (sequoianursery.biz)- Ralph Moore’s own root nursery sells minis and many other types on their supplemental list.
Rosemania (rosemania.com)- Some of the newest show and Robbie Tucker’s own mini and miniflora roses. Good quality and service.
Nor’East Miniatures (noreast-miniroses.com)- good mini supplier.
Bridges Roses (bridgesroses.com)- Good exhibition mini supplier.
Many Dennis Bridges and Michael Williams roses.

 

Why did my yellow rose turn white or red?

Most roses are budded plants. The desired rose variety is bud grafted onto a different rootstock. This is a variety that is very vigorous and will do well in most parts of the country. Budding plants allows growers to produce larger plants quickly to sell with less time in the growing fields. The budded portion is the bud union, the round portion coming off the roots that the green canes emerge from. If this section dies, sometimes the rootstock will still grow, producing small non-descript red (Dr. Huey) or white (rosa  Multiflora) flowers. Both of these varieties will only bloom once a season, as opposed to the continued flowering of the variety that was grafted to the rootstock. This will make it seem that the rose has changed color.

Budded roses can also send up suckers, which are canes coming off of the rootstock. These will be thinner more pliable canes, usually lighter green in color and usually with more leaves on each leaflet. They will also flower white or red, giving the appearance of having two different color flowers on one plant. These should be removed, because if not, the root stock may eventually take over and the budded portion of the rose will die off. This will leave you with a rose that blooms once with small red or white flowers. To remove these gently remove soil where they emerge and break or cut off the sucker as close the roots as possible.

If the rose is completely changed over to one of these rootstocks you can not reverse it. You must purchase a new rose or grow the remaining rose that will only bloom once a year.
