For sale is one rhyzome of Water Lily – Karleen Harder Nymphaea spp.
This water plant will come bare/loose rooted and you will need to plant it when you recieve it.
Water lilies go dormant for the cold winter, so please remember that they may not look like the photos if you order during Melbourne's winter. They may have little or no leaves. They will just be a dormant rhyzome. Plant it as per our instructions, and watch it grow as spring warms up.
Karleen Harder is a very hardy water lily. Green leaves are heavily speckled with purple blotches becoming green as leaves mature.
Provides shelter for fish and frogs from sun and predators.
FLOWERING: Attractive sunset coloured flowers with star shaped two toned petals that change from peachy to yellow. Flowers late spring into summer and early autumn. Flowers sit just above the surface of the water.
HEIGHT: The plant will grow to a width of one metre.
POSITION: Grow in full sun in ponds, around the edge of dams and wetlands 30 – 120cm deep. Can also be grown in decorative pot with no hole. Plant at bottom of pond and new leaves will grow to surface. They require at least 4-6 hours of direct sun light per day to produce flowers.
FROST: Frost hardy.
Karleen Harder is likely to retain leaves over the cooler seasons in temperate to tropical climates.
During the winter period in cooler climates, it will have smaller winter leaves.
CARE: Fertilise in spring with one of Triffid Park’s water plant fertiliser tablets to encourage new growth and flowers at the start of the growing season. Then again at the start of summer and at the start of autumn to encourage healthy growth and green foliage.
Water lilies do not like splashing fountains, so still or slow moving water is best. Anything from small tubs with no holes, to ponds, lakes and dams.
In a decorative pot, think of them as a potted plant, growing in water, and then you can grow it on your patio, verandah, balcony etc.
FERTILISER: Triffid Park's Water Plant Fertiliser Tablets are available on our Water Plant Sundries page. There are no nutrients in a plastic pond or tub, so these are a definate must when potting your water plants, and for fertilising 3 times per year.
