Higher latitude ( but not too high) makes for a longer growing season, such as in the Prairie Provinces of Canada : https://en.m.wikipedia.org/wiki/Palliser%27s_Triangle

<p>Is the length of time, say months, for each season the same all over the world or can it vary? </p>

It depends of what you call a season: http://earthscience.stackexchange.com/a/2603/111

If one defines seasons by the equinoxes and solstices, then they are identical worldwide.

As has been noted in a comment, it depends on how you define seasons (see <https://earthscience.stackexchange.com/a/2603/111>).

If seasons are defined in astronomical terms, then they have the same length everywhere on the planet. This is simply down to geometry.

However, the *effects* of astronomical seasons vary geographically in a number of ways. The magnitude of seasonal changes, for example changes in day/night lengths, is more pronounced in higher latitudes, so the effect of (for example) winter might be noticeable for a shorter time period in the tropics than the arctic, and hence some people might reasonably consider winter to be shorter there. There are other, less systematic variations that depend on local climate and weather.
