There is nothing as inspiring as sitting in your garden looking at your flowers and watching the face of a child light up when they see a butterfly flit over the Pentas or a hummingbird hover by the Salvia or bees busily buzzing from Alyssum to Nepeta blooms. Even as an adult, watching pollinators at work is fascinating!
If you are serious about attracting these lovely creatures, a garden that includes plants for the entire life cycles of the pollinator will be best. There are several parts to the cycle (depending on which pollinator we are talking about) but, food (nectar source), shelter, water and in some cases host plants are what you need. Plant with intention for these needs.
