i have no earthly idea what kind of seed/plant this is..a friend gave me several of them and told me to plant them in my aquarium. i'm a bit skeptic...she says they take about a month to sprout once in the water, and bloom into long thin-wire-y stems with leaves on top that spiral? have you seen this before? thanks!
