Miniature water plants fill these ceramic cache pots. The largest pot (5 1/2 in. diameter, 5 in. tall) features a dwarf papyrus (submerged in its nursery pot) and duckweed.
The midsize pot (4 1/2 in. diameter, 4 in. tall) holds frogbit with duckweed (both are invasive; keep them away from natural waters).
The small pot (2 1/2 by 2 1/2 in.) contains duckweed.
