GROWTH RATE: Vigorous

USDA ZONE: 3b-10b

EXPOSURE: Full sun; 4-6 hours of direct sun per day, ideally in the morning

WATER & SOIL: Medium, consistent water; avoid wetting leaves when possible. Prefers well-drained, neutral to slightly acidic soil with plenty of organic matter.

BLOOM TIME: Spring, summer, fall; reblooming in flushes throughout the season

REBLOOMING: Yes

FLOWER ARRANGEMENT: Clusters

FRAGRANCE: Moderate to strong fragrance

PLANT ORIGIN: Indigenous to Asia and Europe, but hybridized all over the world for thousands of years

WILDLIFE SUPPORT: Limited - Most roses have little utility as hosts for local insects and wildlife, since they are heavily hybridized plants from other parts of the world. Flowers may provide food for pollinators while blooming.

FERTILIZING: Fertilize monthly during spring and summer by top-dressing with compost or applying any nitrogen-rich fertilizer. Stop fertilizing in fall to allow the plant to go dormant for winter.

PRUNING: Climbing roses tend to require less pruning than other roses, especially if you want your climber to grow tall. Prune reblooming varieties in late winter or early spring while dormant, and remove spent blooms during the growing season to encourage reblooming. For single blooming varieties, prune just after flowering to avoid removing next year’s flower buds. When pruning, remove dead branches and older canes that no longer produce flowers. Keep in mind that climbing roses don’t naturally cling to walls, so you'll need to fasten the canes to a support structure such as a trellis or arbor. Place supports at least a few inches away from walls to promote airflow. For more detailed advice on pruning and shaping roses, many helpful resources are available online.

TOXICITY FLAGS: Roses are non-toxic to dogs, cats, and horses. Ingesting too much plant matter may cause mild gastrointestinal symptoms. Thorns can create small cuts if your pet rubs against them, and can damage the digestive tract if eaten. Remember to also check the safety of any fertilizers or pesticides used on your roses.

USES: Ornamental specimen that climbs arbors, trellises, and walls; Cut flowers

DISEASE PREVENTION: Fungal diseases like black spot and powdery mildew can be a persistent nuisance for Middle Tennessee rose growers. Here are some tips to limit fungal infections:

Avoid letting water sit on the leaves when possible. Water around the base of the plant rather than getting the leaves wet (though nature sometimes has its own plans).

Always use clean tools. Disinfect pruners between every cut using rubbing alcohol or a 10% bleach solution (i.e. 1 ounce bleach + 9 ounces water).

Space roses to promote good airflow and reduce the risk of disease transmission from one plant to the next.

Regularly remove fallen leaves and debris from around the base of the plant. Replace winter mulch in spring.

In late winter, coat the entire plant with dormant oil to suffocate pests and control diseases.

If you have persistent problems with fungal diseases, consider regular applications of an anti-fungal spray like copper fungicide or neem oil as a preventative measure.

Another rose pathogen to keep on your radar is Rose Rosette Disease. Caused by a virus and spread by microscopic mites, it currently has no known cure. Symptoms include deformed, reddish new leaves, excessive thorn production, and stunted growth. If your rose bush is infected, immediately remove, bag, and dispose of the entire plant to contain the spread of infection.

PARENTAGE: Sport of Blaze

HISTORY: This rose's history begins in the United States and journeys to Czechoslovakia and back again. The original Blaze climbing rose was bred in the U.S. in 1932 by Joseph Kallay. Shortly after, Czech rose grower Jan Böhm planted Blaze roses in his hillside garden, and in 1935 he discovered the sport that became Blaze Improved. A decade and a half later, Blaze Improved was introduced back to the United States in 1950, where it is grown to this day, a testament to the international nature of rose breeding.
