Types of Water Lilies Beginners! Go for the hardy lilies due to the fact they may be easy to plant and keep. They will bloom even in winters if planted under the freezing line of the pond. Tropical water lilies, then grow extra inches again, need a touch more care and interest. But, the wait is really worth the effort due to the fact they have more potent fragrance and their plant life bloom even in colourful colours of pink and blues.
