Larger rock. Not suitable for large box and small pot planters, but good for ground garden for an exotic, bumpy feel. Choose only one file.

Smaller model with a trimmed rock to better fit into large box planters. Small pot planters will still clip. Choose only one file. (updated to stick a bit more above the soil)

The smallest model, adjusted for the small pot planter. Easy to harvest from pot and box planters, but in the ground garden the harvest prompt is above - though easily pinpointed because it's wide. Choose only one file.
