Hybrid Tea Rose Compendium

Hybrid  Tea Roses

The hybrid tea is one of the most popular form of the modern rose after 1945. 
It is the classic, single-long stem cut flower.  It is a vase-shaped bush with upright stems; each topped with usually just one flower. The average hybrid tea repeats its bloom on each stem every 6 weeks and grows 4-5 feet tall and 3-4 feet wide.  There are some varieties that don’t produce a superior flower until their second year.  There are some hybrid tea roses can produce multiple flowers per stem when growing vigorously.  These extra buds may be removed (when first noticed) for best flower quality (a technique called dis-budding).  A few varieties that require extensive dis-budding are noted in the list.  Some heavily petaled varieties tend to “ball” in early spring.  The bud enlarges but won’t open because the moisture from drizzle, mist or dew is making the petals stick together.  Removing “balled” buds encourages the next round of blooms.  This affect is more common near the coast, than inland areas.

Rose  Rating  Scale: 
Ratings are based on color, fragrance, form, lasting quality, disease resistance, and abundance of bloom. 
Roses are scored from 1 to 10; 10 being nearly perfect.
Roses with a rating of 8 or higher are a reflection of superior characteristics.  

Mildew is the single most commonly encountered problem, therefore resistance to it is an important attribute when selecting roses. 
Mildew is a fungus that looks like a thin white or gray coating on the surface of developing foliage, stems and buds.  Mildew can distort or even halt further growth. 
No rose is totally immune to fungus. Blackspot is another common problem with some roses.

Mildew Ratings - aka (MR)
MR=10, 9 have the strongest resistance.
MR=8, 7, 6 have good resistance, but may get some mildew as the ratings go lower.
MR=5, 4, 3 will get mildew if not treated. 
Descriptions are no substitute for a good photograph.  Be aware that rose colors do change during different weather conditions and that photos on the internet are generally more accurate than coloring shown in a printed catalog. 

Exhibition Roses have classic upward facing blooms with spirally arranged petals tightly wound with a high center, while the outer petals are wide open and slightly reflexed.  The stems are long and straight.  

Fragrance is normally strongest on a sunny day with little air movement and moderate temperatures.  Be aware that old noses don’t detect fragrances as well as younger noses.   Fragrance is difficult to quantify.
