There is no count of the type of roses that adorn gardens. Some roses have dense petals, some open up slowly as the one you see in the photo. This rose took several days to fully bloom.
I have seen roses growing on creepers with clusters loaded. Some roses have a great scent but noticeably ordinary looking.
They all have names – tea roses, floribunda, grandiflora, hybrid, polyantha ………the list is endless. This link has more details
And finally is there anyone on earth who does not like roses?
Do you have roses in your garden?
