On Wikipedia Gravel has a short entry. However, it includes a section titled ‘Relationship to plant life.’ It says: “In locales where gravelly soil is predominant, plant life is generally more sparse. This outcome derives from the inferior ability of gravels to retain moisture, as well as the corresponding paucity of mineral nutrients, since finer soils that contain such minerals are present in smaller amounts.”
Well, we have Exhibits A through E over here of what happens when one is a negligent seed planter. It appears seeds can grow as well (possibly better), when mistakenly dropped on the ground. Behold the following gravel plants, which might be borderline miraculous!
