Marginal Plants for the Pond III

Isolepsis cernua (syn. Scirpus cernuus) – Fiber optic Grass features graceful arching fine green stems that are each tipped on the end with tiny flowers, giving the appearance of one of those 1970’s fiber optic lamps. It is treated as annual here in coastal BC although it often self-seeds and can also be overwintered as a houseplant. Grows 10-14″ high by 12″. 0-2″ water depth. Z8.

Schoenoplectus lacustris sub. tabernaemontani ‘Zebrinus’ (syn. Scirpus zebrinus) – Zebra Rush has very upright hollow stems of bright green irregularly banded with horizontal pale yellow bars that fade later in summer. The small brown flowers are insignificant and it can be divided in early spring. Grows 3 to 4′ high by 12-18″ wide. Water depth 3 to 12″. Hardy to zone 4.

Typha latifolia ‘Variegata’ – Variegated Cattail is a vigorous marginal plant suitable for larger ponds or lake-side plantings (where it can’t escape). It also makes an excellent specimen feature in large tubs. The strap-like green leaves are generously striped in creamy white and it bears your typical cinnamon brown cattails. Grows 4-5′ high. 0-12″ water depth. Hardy to zone 5.

Schoenoplectus lacustris sub. tabernaemontani ‘Albescens’ (syn. Scirpus albescens) – White Rush has very upright hollow stems that are heavily streaked in creamy-white, darkening to green with age. This is not a good choice for exposed or windy sites as the stems are easily blown over. The tiny brown flowers are insignificant. Grows 3-4′ high by 18″ wide. 6-12″ water depth. Z4.

Juncus effusus f. spiralis (syn. Juncus effusus ‘Spiralis’) –  Spiral Rush is reliably evergreen here in coastal BC with stems (up to 1/4″ thick) shaped like malformed springs that spiral out in all directions. The stems can also be used as greens in cut flower arrangements but the small brown flowers are not very showy. Grows 12-18″ high by 9-12″ wide. Water depth 0-2″. Zone 4.
