In the mid 1980s, isolated occurrences of Rigid Hornwort had established in the lake, and, by the mid 1990s, abundant quantities of other aquatic plants such as Ivy Duckweed and the liverwort Riccia Fluitans, were reported along open edges of the lake.

Plants with small leaves, such as Eleocharis acicularis, Glossostigma elatinoides, Hemianthus callitrichoides, Riccia fluitans, small aquatic ferns, and Java moss (Versicularia dubyana or Taxiphyllum barbieri) are usually emphasized, with more limited colors than in the Dutch style, and the hardscape is not completely covered.
