Creepers are plants that spread horizontally along the ground. What helps creepers anchor themselves to the soil as they spread?
Adventitious roots at nodes
Creepers grow horizontally along the ground and develop adventitious roots at their nodes, the points along the stem where leaves attach.
These adventitious roots grow downward into the soil at intervals along the stem, anchoring the plant firmly as it continues to spread outward.
Aerial roots gripping walls and tendrils coiling around supports describe climbers rather than ground creepers, and hooks on stem tips are not the anchoring mechanism used by typical creeping plants.
