What is a one-sentence summary of the following article?
Spring-flowering bulbs are most visually appealing when a variety of flowers are planted in an arrangement. Depending on your level of gardening experience, you may want to start out with only 2 or 3 types of spring bulbs. If you’re confident in your gardening skills, select a half dozen bulb varieties. Purchase at least 3 or 4 individual bulbs of each variety. Popular combinations of spring bulbs that can be planted together include:  Tulips, daffodils, and snowflakes. Bearded irises, Siberian irises, crocuses, and bluebells. Snowdrops, crocuses, and hyacinth. Note that the bulbs in each combination are roughly the same size and can be planted at the same depth in the same hole. Nearly all plant nurseries stock bulbs year-round. If you visit the nursery in the fall, around September or October in the Northern Hemisphere, their selection of spring-blooming bulbs will be at its largest.  Healthy, high quality bulbs will be rounded and firm, and not have any cracks or wrinkles on their surface. If there isn’t a nursery in your area, many large home-supply stores have an onsite gardening center. If you don’t live near a brick and mortar nursery or garden center—or if you prefer to shop online—you can find a wide variety of bulbs through seed catalogs. Search by flower name until you find the type of bulbs you’re looking for. If the bulbs are organized by growing season, search for “spring-blooming bulbs.” For example, look through the online bulb selection at Gurney’s, Park Seed, or FedCo Seeds.

Summary:
Select a variety of flowers. Purchase bulbs at a reputable nursery or gardening center. Order bulbs from an online seed catalog.
