It sounds like 'Little Gem' needs special placement then. By a path so you can look closely at the tiny blooms, but a height of 2m says back or middle of the border to me. The description on the 'Little Gem' page says short, compact and 3 to 4 feet high. I hesitate to increase this to 2m in case your soil is extra specially good, and 2m is not a normal height. Patricia
The place in my garden it stood, had no particularly good soil: Boulder-clay. And wasn't fertilized extra. It stood in front of the bed, but wasn't at it's place. I replanted it in the middle of a group of Virginiana shrubs. It differs in height (maybe it likes that kind of alkaline, rich on trace elements, soil), but the other characteristics match.
Replanted and relocated under the oaks it even gets bigger. It is not really a monster, but catches the eye(-sight) of people interested in unusual roses.
At my place, it reached a height of 7 feet in just two seasons! A lot higher than expected (and mentioned at HMF); it will be replanted at another spot in the garden. It stands in almost pure boulder-clay. The ground is covered with rotted manure and compost.
