FruitThe fruit is called a schizocarp. It consists of three segmented, wrinkled, green pods, each containing a single, wrinkled, large brown seed.
LeavesRounded (obicular), green, reminds me of a lily pad. The leaves contain mustard oil, used in salads along with the flowers and buds
StemsThey are long, smooth, and succulent, and herbaceous. The stems are typical of the plant's tender annual growth, as a trailing, spilling plant.
DimensionsAround 12" tall by equal spread, has a floppy growing habit
MaintenancePlants tend to flop; pruning is needed to maintain good form.
PropagationSeeds are very large; they can be planted "in situ" after the danger of frost has passed, or direct-seeded into a peat pot. Soaking may help germination.
Native SiteNative range is the cool highlands of Mexico and Central America.
Misc FactsTraeolum comes from the Latin word tropaeum, meaning “a trophy”. The leaves were thought to resemble the helmets and shields that were present at Roman triumphs. Nasturtium means bitter leaves.
Author's NotesI have grown many different Nasturium. I always liked the flowers, but they all have the same growth habit; they tend to flop. Work nicely in the garden where they can mingle and grow among the flowers. Works well as a spiller in containers.
