title_body: Is it possible to grow plants in used coffee ground so that they get coffee flavor?
upvoted_answer: Adding coffee grounds to a planting medium (e.g. soil) adds fatty acids, essential oils and nutrients that enrich soil which can help the growth of the plant and it may also affect the colour. One thing to be careful of is that some coffee grounds increase the acidity of the soil. However, I can't find anything indicating that it will affect the flavour of the plant. So, by all means, grow your plants in coffee grounds, but don't expect any difference in flavour.
