Perennial daisies should be chosen for the garden based on the type of sunlight the area receives, how much water reaches the plants, and the wildlife indigenous to the region. Dozens of varieties of these types of flowers may be purchased to brighten and add interest to any flower bed. Each type of plant produces a different color of blossom, can grow to varying heights, and requires a unique formulation of sunlight, shade, and moisture. With proper care, these flowers are guaranteed to come back each year and bloom again, often reproducing during the colder months to create a fuller display of blooms in the summer.
The gardener can begin considering which type of perennial daisies are best for his flower beds by first determining the amount of sunlight they receive throughout the day. Most varieties of daisies prefer full sun to partial shade, and do not grow well in full shade conditions. Traditional black-eyed susans and gerbera daisies are among the more hearty of these flowers, and can tolerate more shade than other more hybrid versions, such as the coreopsis.
Second, the gardener should decide how much water the portions of the garden under consideration are capable of receiving. Certain varieties of perennial daisies, such as the Stoke's Aster and Coneflowers, require moist, well drained soil. These daisies will not thrive if planted in acidic, clay based soil, which typically retains water after rains and becomes dry and hard once drained. A mixture of sand and loam or organic compost can be used to create an ideal home for such plants. More hardy daisies, like the Shasta and the Painted versions, are semi-drought tolerant and can be planted in less ideal soil and water conditions.
Once the gardener is confident of the amount of sunlight his garden receives and how much water he can provide, he may finally consider the type of wildlife in his area. Gardeners in regions that are prone to high populations of deer may benefit from purchasing perennial daisies that are deer resistant, and will not be eaten away out of their flower beds days after planting. Those who wish to create a haven for butterflies and hummingbirds may enjoy the types of wildlife attracted by the Stoke's Aster and Azure Fairy Aspen daisies. The benefits to each type of plant are typically listed on seed packaging, or can be listed in detail by local garden shop owners.
