Nymphaea Rosanna Slip

Nymphaea Rosanna Slip


A beautiful solid candy pink colour makes up the gorgeous Nymphaea Rosanna Slip. This multi-petalled hardy waterlily is a medium sized plant with the flower sitting slightly above the waterline. Best suited to medium to large ponds or watergardens. 

  • Origin

    The Nymphaea Rosanna Supreme is a Randig creation, one of the few Hardies created by Randig who usually specialised in Tropical Waterlilies. It was hybridised in 1957.

  • Planting out

    When planting out your waterlily rhizome, we suggest planting out in a normal squat pot, which can sit comfortably in your pond or waterbowl. Half fill your pot with a good quality top soil and a half a handful of nutricote or your preferred waterlily fertiliser (ensure that the fertiliser has no added wetting agents). Plant your lily and gently cover with top soil until the pot is filled about an inch from the top of the pot. The cover the surface with a small washed rock, approximately 5-10mm in size. Submerge the pot into your pond or waterbowl so that the longest leaf can float comfortably on the surface.

  • Placement in the Pond or Watergarden

    Hardy Waterlilies will need somewhere between 5-6 hours of sun at a minimum per day, and a growing space of approximately 25cm - 1m deep. (or 20-30cm for miniature waterlilies).

    When deciding where to place your pot in the water feature - pond, pot or dam - ensure to pick a place with no waterfalls or fountains. Waterlilies and many other water plants of not like to have their leaves splashed continuously. Gentle moving water will be ok for most, but try to pick quiet area in the water garden.

    Also when picking a place for your nymphaea in the watergarden, be aware of what may fall into it. Waterlilies and many other water plants will not do well with an excess of tannins, especially from gum trees, in the water. If the levels are too high it could damage your water plant or even cause the death of the plant.

    Once you have chosen an appropriate spot, place your pot into your water garden with the longest leaf floating above the water. It is essential that some of the leaves are floating on the top of the water so that the plant can photosynthesize and grow.

  • Seasonal Notes

    The colder the climate, the more sun you waterlily will require. In the top end of Australia, you nymphaea may need only 4-5 hours of sun per day, whilst in southern Australia, it is suggested that at least 5-6 hours are required as a minimum. As a general rule, keep them in as much sun as possible!

    Growing seasons are also dependent on climate. Here in the top end of Australia, with more hot and humid climates, waterlilies will grow all year round! This is why Territory Exotics and Watergardens has waterlilies for sale all year!

    In colder climates, such as Southern Australia, you must be prepared that your waterlily will go dormant during the winter months, and may lose its leaves. You can expect growth seasons to be around October to April, and this is where your waterlily will produce its stunning flowers! This continues during warmer months, usually finishing up around April for hardy waterlillies.

  • Ongoing Care and Fertiliser

    Feed your waterlily with 2 agriform tablets every 6 weeks throughout its growth season. In warmer climates, where nymphaea grows all year around, this means keeping up to date with your fertiliser all year also! However in colder climates, start your fertilisation just before the growth season begins, around August, and continue adding fertiliser until February or March.


    As always, keep green algae to a minimum in your pond by simply scooping it out of the water when there is excessive build up. Continue to scoop the algae out until your pond finds its natural balance as your waterplant continues to grow. We suggest avoiding the use of chemicals or cleaners, however if you are concerned about the health of your pond, consult with a pond specialist in your area.
