What is the difference between a shrub rose and a grandiflora rose or a floribunda rose?

Crossing polyanthas with hybrid teas produced the floribunda class. These roses are shorter than the average hybrid tea and produce blooms in clusters. The grandifloras are crosses between hybrid teas and floribundas. Most of them resemble tall floribundas with high-centered blooms. Shrub is a "catch-all" term for roses that don't fit into any other category, such as David Austin's roses, the Meilland and Kordes landscape roses, and the hybrid rugosas.

A shrub rose looks shrubby. They usually have "single" roses (roses with 5 petals) (I think) and are usually shorter plants. A grandiflora rose has blooms that are usually a single bloom to a cane and are tall & leggy. Think of a florist rose. A floribunda has LOTS of blooms on a single cane, kinda like an instant bouquet.

Grandiflora - "Octoberfest"

Floribunda - "RedGold"

Shrub - "Kordes Brillant"

Of course I could be 100% wrong with all of this, too. Smiling But that's how *I* remember them.

Grandifloras actually bloom in small clusters of 3-5 blooms. Roses with one bloom per stem, such as florists roses, usually are hybrid teas.

Shrub roses can be short because the class includes patio roses that are too big to be classified as miniatures, but many are quite tall (the Meilland and Kordes landscape roses, the David Austin roses, and the roses produced by Clements, Buck, and Shoup in this country). Petal count varies in the shrub class. Some are single roses, but others, such as the Austin roses, can have up to 100 petals.

Speaking ONLY for myself, here's how I remember it:
The hybrid teas are the ones that are mostly dead in the spring.
The floribundas are the ones that have too many green canes for me to prune.
Grandifloras have one big tall thick stick in the spring. Might or might not be green.
Shrub roses are the ones I don't prune, that I can plant anywhere in the yard, that hardly ever spring a Dr. Huey shoot, and stay clean of disease without any action on my part.

I would say your rule of thumb for rose classification would apply quite well here too.

The shrub class can get confusing. For example the Buck rose Honey Sweet, my favorite rose is classified as a shrub, but has single hybrid tea type blooms. I wish that I could grow hybrid tea roses as hardy and disease resistant as Honey Sweet.

Another thing that I wished that I knew when starting to grow roses - miniature roses have tiny leaves and flowers. Many of them are also tiny plants. Some, however, can get really tall but still have tiny leaves and flowers. Best to do research. Also, many of the grocery store minis are very hardy. I have some that survived for years in my garden and are still alive!

Another think that I learned the hard way, rugosa roses HATE being sprayed. They are happiest fending for themselves away from their fussy, well fed cousins.

A floribunda is a rose that bears blooms in bunches on a moderate sized bush. It is a cross between a hybrid tea and a polyantha. A grandiflora tends to be a tall plant resulting from a cross of floribunda and hybrid tea. Shrub roses are a mixed lot that are generally tough landscape roses of various lineages.

While technically true, I feel you may have gone a bit far in the opposite direction. The leaves and flowers are smaller yes but the range is significant. I mean I have a moon river (or Gra's Blue...have both, very similar just slightly different colour and very different scent) next to Friesia (aka sun sprite) the difference in size is not that significant, blooms about 3/4 the size, plant height close to a meter, leaves by no means tiny.

On the other hand if I compared it to Rise N Shine then the blooms and leaves are around half the size of Friesia.

There are really tiny minatures out there but they aren't the norm. Most of my rose garden is minatures (and a few hybrid tea's and floribunda) and most are close to 2 foot tall with blooms around half the size of floribunda....but often many more blooms happening at the same time.
Anyone with oryzalin (aka Surflan, Embargo), am looking for a small amount rather than 5litres from manufacturer (min size in Australia....)
