Here is a species in which we can find many varieties, all equally beautiful and delicate;
personally, I love greatly the waterlilies and, if not against the most elementary rules of garden design, I would cover the entire surface of a lake, large or small, with these incredible flowers. As you know, the waterlilies can grow in conditions of high, medium and low deep of the water, but care must be taken to choose the right model of flower, suitable for each situation. All waterlilies have floating leaves and the flowers are all of great beauty and charm, closely resembling the lotus of the East regions. I love greatly the water plants, they are so incredible: most terrestrial plants cannot tolerate having their roots submerged in wet soil or in water, but, for these water plants, these conditions are beneficial, even vital, to their survival. The waterlilies have a wide range of colors, shapes and fragrances, they bloom from the early summer until the first frosts of winter, creating very pleasant spots of colorful flowers, floating gently on the water surface. The hardy waterlilies can survive a cold winter climate, their only requirement is that they must be protected from a hard freeze during winter. All waterlilies are day blooming, their flowers open in the early morning and then close in mid to late afternoon.

All waterlilies are widely used for decoration of garden ponds and, in my opinion, there are really necessary to create a water garden of great charm and grace. Most are white or pink, though a few are reddish in color, certain species are very small, miniature even, but others are very large and can be so rampant as to overtake a natural pond in few years. Some waterlilies even change color as the flower ages: most of these blossoms start light yellow, mature to a reddish-orange over the next few days and, finally, reach a darker red for the last day before fading completely.

All species of water lilies that I will mention in the article, have the following common features: all tolerate the climatic conditions of the zones 5-9, all require a position constantly exposed to sunlight and, above all, stagnant water.

-Plants for shallow-water

Because of their size, very small, dwarf or pygmy waterlilies are ideal for plants grown in shallow water (15-45 cm). Some of them are real pygmy waterlilies, other are smaller versions of traditional waterlilies. The dwarf and pygmy waterlilies should be grown in baskets or planted directly in the soil of the pond. Must have constant sunlight and the water, as for all species of waterlilies, is to be stagnant. The water depth varies by species, and then I show you the depth needed for every variety of flower. In most cases, the width of the plant corresponds to a time, or one and a half, the depth at which it grows.
