📦 Shipping & Live Plant Notes

Plants are carefully packaged to help ensure they arrive healthy and ready for planting. Some minor melting or leaf loss may occur as the plant adjusts to a new aquarium environment. This is normal and new growth should emerge as the plant acclimates.

⚠️ Due to the natural variation of live plants, each plant may differ slightly in size, color, and shape from the photos shown.
