Care

Warning: Nodding lady's tresses is a land (or at most bog) plant, not a true aquatic plant. Kept fully underwater it slowly weakens and dies, often over several months, so it is best grown emersed in a paludarium or with only its roots in water. Spiranthes cernua is a North American ground orchid of wet meadows, mossy seeps and sphagnum at pond and lake edges. It grows up to 50 cm tall, with a few narrow upright basal leaves and a spike of nodding white flowers arranged in a spiral, from late summer to autumn. Although it appears on Wikipedia's aquarium plant list, it grows in damp ground, not under water. It is a temperate plant that needs a cool winter rest. Suitable only for a bog garden or a carefully managed paludarium with moist, acidic, mossy ground.

Breeding

Orchids of this genus are hard to propagate: established plants can sometimes be divided when dormant, and seed needs a specific soil fungus to germinate. Only buy nursery-raised plants; never collect them from the wild.

Compatibility and tank mates

Not an aquarium plant. Grow it in a bog garden or moist, mossy paludarium area above water; do not sell or buy it as a submerged aquarium plant.
