I've read that there are roses that bloom all year in warm climat. Would such a rose bloom inside the house in winter? Which one? Do they need rest? Often, nice blooming is interrupted by frost, could it go on for my pleasure inside?
Many thanks

Blooming is not only affected by temperature, but also by light. In our winters, sunlight intensity is too low for blooming. Also, roses in the house are susceptible to mildew and thrips.
On the other hand, you might get an earlier bloom if you take in a potted rose into a cool room in February.

If you do a search of the Q & Forum archives (click the SEARCH POSTS tab at the top and put "indoors" in the SEARCH field.), you will see several posts about growing roses indoors.

Greenhouse growers grow roses for cut flowers year round. A flyover of the Netherlands at night will show you what it takes at your latitude -- a glass greenhouse and lots and lots of extra metal halide lights operating for several hours at night (and during cloudy days as well.) Without the required lux or footcandle hours each day, rose plants won't bloom well or at all.
