Abstract: A modular plant support system for aquatic environments assembled from a plurality of elements to facilitate varying configurations. The modular plant support system generally includes a generally planar platform, a base or basket, and at least one platform support member extending between the generally planar platform and the base to operably couple the platform and the base. The platform is capable of receiving a potted plant thereon, and the base has a bottom portion, a top portion, and at least one peripheral side portion providing an interior cavity. The modularity and flexible connectivity coupled with the structural stability of the system enables the respective aquatic plant to be selectively placed at the optimal aquatic elevation.
