Duckweed : Lemna minor
$4.00
Plant type: aquatic plant
Height: 1-3mm
Light: full sun
Soil: none! fully aquatic
PPL: YES
Appropriately nicknamed 'water lentil', each with 1-4 leaves and a single inch-long root hanging down. Helps to keep your pond shaded during hot summer days, and give cover to the chorus frogs.
Spreads rapidly, but easily managed with some removal with a small rake (dump on your land plants for added nutrients!).
Comes in a small cup? Bag? We haven't decided...
