- Flowers that grow well in containers usually require at least six hours of sunlight per day. Place abundant plants into the container to give it a full appearance. Choose plants that complement each other. Ensure each variety planted in the container receives the required water, fertilizer and lighting to coexist. Container flowers benefit from a slow-release fertilizer applied during the summer months. Comprise each container of a variety of annuals or perennials. Coordinate flower colors to complement each other.
- A large tub or half-whiskey barrel provides the perfect container choice for large-growing flowers, such as celosia or zinnias. Both flowers grow well in a small container, but provide a truly impressive visual appeal when planted en masse in a large tub. Dwarf celosia rarely exceed 4 to 6 inches in height, but other celosia varieties tower 3 feet. The larger varieties benefit from the added weight and growth area that a large pot provides. Consider establishing five zinnia plants in a pot that measures 14 inches in diameter to offer a multitude of nonstop blooms.
- Creating a flowering hanging basket helps conserve valuable floor and railing space in a limited area. Consider a deep, wide basket to provide ample space for the flowering plants. Ensure the container has drainage holes in the bottom -- so the water can flow freely out during irrigation or a rain storm. Both the tuberous and wax begonia grow well in hanging baskets. Also, consider planting the annual browallia in a hanging basket. Place approximately six seedlings in a 6-inch hanging basket. The plant produces blue and white flowers virtually nonstop during the summer months.
- Even a small container that only measures 4 to 6 inches in diameter provides ample space for a small, flowering plant. The tiny pot usually rests with ease on a window sill or along a porch rail. Consider planting a petunia or a pansy in a small container. Available in a wide selection of bloom colors, the annual plants provide continuous blossoms throughout the spring and summer months. The annual vinca grows to form a mound of dark green foliage topped by small flowers in shades of pink, red or white. Flowers appear from spring to fall. The vinca averages only 6 to 13 inches in height and grows in a small container. This plant is drought tolerant.
