Because> They have small roots that can not stay in the ground!
Plants that grow best in sitting water are typically referred to as aquatic or marsh plants, such as water lilies, cattails, iris, and rushes. These plants have adapted to thrive in wet environments and are able to absorb nutrients and oxygen from the water. It is important to ensure that the water is not heavily polluted or stagnant to support healthy plant growth.
Algae do well in ecosystems with slow-moving water because it allows them to absorb nutrients and sunlight more effectively. Slow-moving water provides a stable environment for algae to grow and thrive, as it helps prevent them from being washed away. Additionally, slow-moving water promotes the development of diverse microhabitats where different types of algae can colonize and coexist.
Any plants that grow in the vicinity of moving water can have their seeds distributed this way for example Willow and Alder.
Water lilies do not eat algae. They extract nutrients from the water and sediment through their roots, but they do not consume algae as a food source. Algae can grow near water lilies in the same habitat, but they are not part of the water lily's diet.
Cattails typically grow in freshwater swamps, marshes, wetlands, and along the edges of lakes and ponds. They thrive in areas with slow-moving or still water where they can establish their roots in the muddy soil.
you water it and put it in a sunny place
They grow in eastern Asia
Nothing lasts forever.
There are several types of plants that grow in ponds some are lillies, and some green type of plants that grow flat on top of the water. Here is a web site I found. http://www.watergarden.org/Shade-Plants
I'm surprised that you wish to remove water lillies from a pond with fish. They do a great job using up poisons and providing shade. Most people pay a small fortune to get them to grow in their pond(s). The only way I know of to remove them is to actually get in the pond and physically lift them out.
Easter lillies are relatively easy to care for, by keeping them in a warm area and not leaving them in large amounts of water, as well as by removing dead lillies in order to promote new buds to grow. http://www.ehow.com/how_4857357_care-easter-lilies.html
Most Lillies grow from a bulb so they are perennial flowers.
All of them grow in Ontario. The Trillium is native as are water and "ditch" lilies (orange tiger lillies) and several varieties of daisies.
no they dont
There are so many varieties, it makes a direct answer difficult. There are daylillies, canna lillies, calli lillies, spider lillies and many many more. Of these listed, daylillies can be the size of a coffee cup, up to 4 feet tall and 2-4 feet in diameter (in groups). Cannas grow from 6 inches tall to almost 7 feet tall. Callis grow from 6 inches tall to 4 feet tall. Spider lillies, 3 feet tall with blooms to 4 feet and 3 feet in diameter. There are dwarf varieties which are smaller of course.
Lillies of the field toil not, neither do they spin. That is a Bible quote. Basically lilies grow with the grace of God and look beautiful.
