Water Garden Plantlist, hardiness and cultivation tips

Water Lily Root rot | Water Garden Construction | In Brief | Invasive Tips...

Availability, varieties vary for access through the season. Large clumps of many varieties are available throughout the year, in a wide range outside of frosty conditions. Vulnerable flowering types are encouraged to be planted outside of their blooming period. When your plant arrives you may wonder, what shall I do with them? This simple guide will help you avoid disappointment I hope. Later in Summer, you will wonder, is this frost hardy, or is this a tender plant, here's a list to look up hardiness with size and growing information... bookmark for future reference!

*Available in numbers, otherwise, limited availabilty • Choice plants, slow growing, forming clumps.....Hardy Plants with the exception of those marked: < Dies in Frost, protect rhisome or corm o<< Tropical, dies below 5°cooooooo

Water Lilies

The Nymphaea~ Growing water lilies prefer a minimum of 8 hours sun, 2 sq.ft of fertile soil, active treatment against lily root rot.... Vigorous flowering should occur from May to September. The crowns of all water lilies must not freeze in Winter

A more complete list of waterlilies currently being cultivated

Water lilies require a special note. Where lilies have failed, clean out and disinfect pools to eliminate the endemic disease lily root rot.

Treat a growing water lily with a range of systemic fungicides, as you would roses, taking care to follow the makers guidelines, reducing to a minimum water contamination.

If a water lily dies off, either it needs better sun or soil, or water lily root rot is taking a hold. This fungus is poorly documented, always check that your lily is from a supplier who actively treats it.

Infected rhizomes and roots slowly turn purple-black and have a pungent odour, a healthy rhizome is always odourless. The fungus will remain dormant long after the lily has died, so never put a new lily in a doubtful pond!

A new lily may be slow to flower in the first year, while it establishes new roots, then flower for following seasons.

Deep Water Marginals

Similar habits to water lilies, needing 6" water depth for Winter protection, useful in positions too shady for water lilies.

Aponogeton distachyus* (Water Hawthorn) < winter below ice in pond

Hydrocleys Nymphoides (Water Poppy) <

Nuphar Pumila minima (Brandy Bottle)

Nuphar Sagittaria (Cape Fear Spatterdock)

Villarsia Nymphoides (Water Fringe)


Floaters Free floating, roots of larger varieties are useful for collecting fish spawn making collecting and isolating hatchlings much easier

 Marginals

Require saturated soil conditions, with water over their roots. While many can cope with grazing from fish, it is best to start them in a solid sided container. Allow for future growth when potting, many marginals can blow over in a strong wind if the plant is not potted securely. Starting marginals that are complimentary in groups is effective, where they merge together to form attractive stable groups

Bog plants are usually supplied as potted plants where possible they will be supplied bare rooted ( Marginal plants are usually quite tolerant of being in a bare root condition)

Bog Plants

Require moist soil conditions, but not completely wet, the soil surface must be clearly above any water level. Many of the marginals and bog types can adapt and blur the water margin.

Prefer to be underwater, usually anchored by their roots. In large numbers, they reduce algae by competing for nutrients. Elodea Canadensis is invasive and difficult to control.
