Elements and Principles of Design
Creating beautiful designs starts with an understanding of the elements and principles of design.
Elements of Design
Floral arrangements utilize the elements of design, including line, space, texture, pattern, form, color, and size, to create attractive designs. Each component (flowers, leaves, stems, ribbons, etc.) in the design can exhibit these characteristics.
- LINE is the visual path the eye follows through the arrangement. It can be straight, curving, horizontal, vertical, diagonal, delicate, or bold, among other things.
- SPACE is the area occupied by the arrangement. It is divided into positive and negative spaces. Positive space is the area occupied by materials. Negative space is the open space not occupied by materials.
- TEXTURE is the appearance or feel of the elements' surfaces in the design. It can be hard, soft, smooth, rough, glossy, dull, fuzzy, bumpy, prickly, or wrinkly, among other things.
- PATTERN is the repeated combination of any of the other design elements, such as color, form, or line.
- FORM is the shape or configuration of the overall arrangement as well as individual flowers within it. It can be circular, triangular, square, arched, linear, or fan-shaped, among other things.
- COLOR is the visual response of the eye to different reflected wavelengths of light. Color can be combined in different ways to achieve different effects or feelings. The primary colors (red, blue, yellow) can be used to create secondary colors (orange, green, purple) by mixing any two. Neutral colors (black, white, grey) can be used to change the value or tonal quality of any color.
- Monochromatic colors are different values or tones of one color (e.g., red, pink, maroon).
- Analogous colors are three or more colors next to each other on the color wheel (e.g., green, blue, violet).
- Complementary colors are across from each other on the color wheel (e.g,. blue & orange)
- SIZE is the amount of space something occupies. Both the individual components and the overall arrangement can be large or small.
Principles of Design
The principles of design are the guidelines or “tools” used to compose the arrangement. The primary principles of design to consider are proportion, balance, dominance, rhythm, harmony, unity, and contrast.
- PROPORTION is the relationship of the components within the design to each other. It is closely related to scale, which considers the relative size of the design to its surroundings.
- BALANCE is the stability achieved when the components of a design are in equilibrium. It can be either symmetrical or asymmetrical.
- DOMINANCE is the emphasis of one or more components in the design. It uses elements such as focal points or accents to draw attention to or enhance interest in specific areas of the design.
- RHYTHM is the visual movement through the design. It is exhibited in several ways, including repetition of design elements, the placement of components at different levels (called depth), and the gradual change or transition of design elements within the design (such as small to large, light to dark, or smooth to rough).
- HARMONY is a quality achieved when all the components of the design interact in a pleasing way.
- UNITY is the oneness that is created when the blend of components all have the same thought, purpose, style, and feeling.
- CONTRAST is the difference between components within a design. When used well, it provides excitement and interest. Contrast is achieved through variation (elements that are similar with minor differences), and opposition (elements that are in complete contradiction with each other), among other things.
Harvesting and Conditioning Flowers
By properly harvesting and preparing flowers, they can stay fresh and be enjoyed longer.
Select the Best
Choose high‑quality flowers, whether from your garden or a florist. When harvesting from your own garden, select blooms that are just beginning to open and cut the stem several inches longer than necessary to allow for later trimming. Use a clean, sharp knife to make a smooth, even cut. Scissors tend to pinch the ends of the stems and close off the water-conducting vessels.
Remove any leaves that would sit below the waterline, as submerged foliage rots, discolors the water, and clogs stems, preventing flowers from getting the moisture they need.
Condition and Store Flowers Appropriately
Conditioning, or hardening, helps extend the life of cut flowers. After bringing them home, re‑cut the stems to open the vessels for improved water uptake, then place them in a clean container. Store the flowers in a refrigerator at 35–40°F for 3–12 hours so they absorb more water than they lose, but never refrigerate them with fruits or vegetables, which release ethylene that reduces vase life. If possible, make fresh cuts on woody stems underwater to prevent air from entering and blocking the vessels. Adding a commercial floral preservative also helps extend vase life. Commercial preservatives are available from florist shops, hobby stores, or garden centers. Homemade options, such as placing an aspirin or a penny in the water, are ineffective as floral preservatives.

Needed Supplies
Find the Right Container
Almost any container can be used for a floral arrangement as long as it holds water. Containers are usually made of glass, ceramic, metal, or plastic, though other materials work as well.
The container should complement the design rather than distract from it, with the flowers remaining the main focus. Its size must also be in proportion to the plant material: low, oblong dishes suit short, wide centerpieces, while tall bottles or vases are better for upright entryway or foyer arrangements.
Holding Stems in Place
The container plays a key role in holding stems in place. Straight‑sided vases provide better support than rolled or flared rims, which allow stems to flare out more readily. Several aids can help secure stems: a simple grid of narrow, clear tape across the opening; pebbles, marbles, or sand in the base; or, in opaque containers, a crumpled 6‑inch square of chicken wire placed inside. More formal mechanics, such as needle‑type or pin‑point holders (often called frogs), come in various shapes and sizes and are adhered to the bottom of the container so stems can be inserted onto the pins.
Floral Foam
Floral foam (often referred to as Oasis® after the most widely used brand) is a lightweight, water‑absorbent material that securely anchors stems while providing consistent moisture, making it ideal for arrangements that require precise stem placement and long-lasting hydration. It’s easy to cut and shape to fit many containers and simplifies creating structured designs like centerpieces. However, floral foam is a single‑use product that can crumble if overhandled, and it cannot be composted. Despite these drawbacks, it can be a helpful tool for beginners learning the basics of floral arranging.
Tools
A few simple tools make floral arranging much easier. A sharp pair of clean pruning shears or floral snips is essential for making fresh, angled cuts that improve water uptake. A small knife can also be handy for trimming leaves or shaping stems. Waterproof floral tape, available in green or clear, helps secure stems and mechanics in place. Floral wire. a thin, pliable, green wire that can be purchased in straight lengths or on a spool at different diameters (gauges), is used to secure stems and structural elements. Floral clay is also helpful for anchoring mechanics, such as floral frogs, in the container.
Constructing the Arrangement
Without Floral Foam
Creating a floral arrangement in a vase begins by filling a clean container with fresh water and floral preservative, then re-cutting the stems before placing them in the vase. Stems can be supported naturally by crossing them in the vase, or with mechanics like a floral frog or a grid of waterproof tape across the opening. After the mechanics are set, add greenery to establish the shape and form a supportive base. Place the focal flowers next, paying attention to proportion, balance, dominance, and other design principles. Finish by adding filler flowers and smaller accents to fill gaps and create a natural, balanced look. When the arrangement is complete, ensure the mechanics are hidden; foliage and fillers often cover them, but materials like marbles, stones, or moss can also be used if needed.
Alternatively, vase arrangements can be made as bouquets and then placed in the vase. Hold the first stems loosely in one hand and let them rest at a natural angle. Add greenery around the outside and base for structure. Then place focal flowers, paying attention to elements and principles of design, such as balance and proportion. Continue adding stems one at a time, angling them to create a gentle spiral that opens the bouquet evenly. Turn the bouquet as you work to keep it balanced from all sides. Finish by adding filler flowers and adjusting stems. Once complete, the entire bouquet can be trimmed level at the base and placed in the vase.
Using Floral Foam
To prepare floral foam, place the block on the surface of a basin of water and let it sink on its own so it absorbs evenly; forcing it underwater traps air and reduces water uptake. Trim the saturated foam with a knife to fit snugly in the container. Floral foam works well in many containers, especially bowls, trays, saucers, compotes, and short square or cylindrical vases. Wedge the foam firmly so it doesn’t shift, and if needed, secure it with waterproof floral tape in a grid or cross pattern. The container should be deep enough to hold at least one‑third of the foam for stability.
Insert stems firmly but gently. Start with greens (foliage or filler) to form a base and cover the mechanics, then add focal flowers with attention to design principles such as proportion, balance, dominance, line, and space. Finish by placing other blooms and fillers to fill gaps and create a balanced look. Because floral foam holds stems exactly where you place them, it works well for vertical, cascading, or radial designs. Avoid removing and reinserting stems, which loosens the foam; if you must reposition a stem, re‑cut it first so its vessels remain open for water uptake.
Tips
- Use high‑quality plant materials that show no wilting, fading, or damage.
- Always condition flowers properly before arranging to ensure maximum longevity.
- Remove any leaves that will sit below the waterline to prevent bacterial growth and cloudy water.
- Cut stems to an appropriate length; stems that are too long make arrangements loose and top‑heavy, while stems that are too short reduce water uptake and vase life.
- Build a solid base of greenery to support the flowers and prevent the arrangement from collapsing or flopping outward.
- Use floral frogs or tape/wire grids to hold stems in place. Using these aids is not "cheating." Mechanics like these are used by professionals and amateurs alike.
- Avoid overhandling stems, as repeatedly pulling them out and reinserting them damages the ends and shortens flower longevity.
- Choose containers that complement, not distract from, the plant materials.
- Ensure all mechanics, including floral foam, frogs, or grids, are concealed. Fill the back with foliage if the design is meant to be viewed from only one side.
- Styrofoam is not the same as floral foam and should only be used for dried arrangements.
- Keep the design visually balanced by considering the “weight” of individual flowers so neither side appears to tilt.
- Make sure plant materials are proportionate to each other and to the container; stem length, flower size, and foliage size all affect proportion.
- Practice regularly. Understanding and applying design principles becomes easier and more intuitive over time.
Care of Your Floral Arrangement
To maximize the life of a floral arrangement, begin with a clean container washed in hot, soapy water to remove bacteria and fungi. Keep all leaves and blooms out of the water, since submerged foliage decays quickly and shortens flower life. Fill the vase with fresh water mixed with a commercial floral preservative. Homemade substitutes such as sugar, aspirin, tea, bleach, or pennies are ineffective and can even shorten vase life.
Place the arrangement in a cool, bright spot away from heat and drafts, and check the water daily, topping it off or replacing it entirely if it becomes cloudy or develops an odor. When replacing the water, give stems a fresh cut if possible. Cut about ½ to 1 inch off the stem to improve water uptake. Designs secured in floral foam or held by a grid or frog should not be removed from the container, but benefit from water changes, if possible.

Rearranging the Design
Often, certain flower species naturally fade faster than others. Remove these stems as they fade to keep the overall design attractive. If the arrangement loses its artistic appeal after dead blooms are removed, consider using what remains to create a new, smaller arrangement. Always recut stems before placing them back into water or floral foam. Foam arrangements may require a new block, as it often falls apart when stems are pulled out and reinserted. Because the stems will be shorter, a smaller or shorter container may be needed.
