I always wondered where these things grow wild, but it turns out that most of the cultivated varieties except one are hybrids. Some are ancient hybrids and others are more modern hybrids.
Questions:
Where do oranges, mandarin oranges, limes, grapefruits, tangerines and lemons ultimately come from for the most part (not including the modern hybrids)?
Which one of these – orange, mandarin orange, lime, grapefruit, tangerine, lemon – is actually a wild growing plant (and is actually one of the origin plants for the cultivated varieties)?
Name the four wild plants that all of the cultivated varieties derive from (hard question).
Name the two types of cultivated limes. Which is an ancient plant and which is a modern hybrid?
Which two are modern modern hybrids: orange, lemon, grapefruit, mandarin orange, or tangerine?
