Just recently, the Asclepias genus was found to contain chemical compounds that double the number of cancer fighting agents. Sunshine is of foremost consideration to butterflies. If possible, make sure your butterfly garden has southern exposure. Butterflies use early morning sun for basking on warm rocks, bricks or paths. As the morning temperatures rise, butterflies commence visiting their favorite nectar sources, but always in sunlit areas, as they try to avoid shade.
Butterflies cherish an area where they can fly without being beat in the air.
That is why, it is recommended to choose a garden spot that is protected from prevailing winds. Trellised wisteria and passion vine can also be used to serve the same purpose. A willow tree barrier may even be suitable for some. Sunny areas that are sheltered from wind and contain such amenities as leaf compost, rock crevices, brush, or even weeds are great places to place your butterfly garden. In addition to planting host and nectar plants around your borders, include them in front of any foundation shrubs, meadow plantings, or woodland edges.
