Butterfly gardens require several things to be successful: plants, water, and the right gardening attitude.
We can easily create lists of plants that butterflies love. Consider planting Asters, Joe-Pye weed, Black-eyed Susans, Lantana, Butterfly Bush, Butterfly Weed, Liatris, Pentas, Coreopsis and Purple Coneflowers. These are gorgeous plants and butterflies will flock to them in large numbers.
Gardeners can easily provide water by soaking the ground in an area next to favourite plants or by having small dishes/birdbaths with water in the garden. By providing water, youll attract butterflies. If you have a small pond, lay a stick on the edge so one end is in the water and one end on the shore. This will provide an easy entranceway for both butterflies and frogs. It also looks more realistic than bare edged ponds.
And finally, we need to create a gardening attitude that says that in order to get those gorgeous butterflies, we need to feed the caterpillars that hatch out to be butterflies. It is OK to plant specific plants these immature insects require and it is OK if they chew them up. You have to have food in your garden for all phases of this...
