If the garden is to be viewed from all sides, the tallest plants should be grouped in the middle, with plants tapering toward the edges of the bed all the way around. Avoid plants that require staking. Perennial plants are best planted in odd numbers for a natural look. For a more refined look, try using fewer varieties and planting in larger groups. Repeating color unifies any design.
Monocultures invite pests, disease, and the potential for failure on a large scale.
Plant cherry tomatoes, plum tomatoes, and beefsteak tomatoes. Look for heirloom varieties that have not been overhybridized for uniformity. And include some native species in your flower garden. With woodland wildflowers it is extremely important to buy from a reputable source that has not pillaged its plants from the forests. Good soil is essential to the success of all gardens, so before planting anything, be sure to tend to your soil.
