It would make sense. Fig trees are so easy to plant and require little to no maintenance so hunter-gatherers could plant the seeds and move on, coming back over the years to gather. Wheat/spelt would require some rather advanced agricultural advances for hunter-gatherers and would probably mean they had to be in a relatively fixed location.
If someone buried a cache of fruit or grains for later, and they sprouted, then it wouldn't take much to figure it out.
