How to Design a Triangular Shaped Flower Bed

Measure the triangular space. Include every square inch, so you can experiment with planting designs. Transfer everything to graph paper for final spacing details. Plan to place taller bulbs in the center of the triangle, for example, if the triangular space is in an open yard. Place taller plants along the back side of a triangular flower bed, if it is against a building.

Create a well-organized look for a very formal garden. Incorporate mulch or small pebbles, for example, to separate and define greenery or bedding plants. Install ground cover between plants as another option. Plant four or five full-size rose bushes in the center of the triangle bed and add a border of dwarf rose bushes for a formal look. Don't add too many types of plants -- roses will provide a formal look from all angles.

Use two triangle-shaped flower beds together for contrast. Divide a large square bed with a board across the middle to form two trianglular spaces. Plant red petunias in one triangle bed and white petenuias in the other. Place coral tulips against bright yellow tulips. Install contrasting, triangle-shaped flower beds to add intense color in a condominium complex or along a poolside at an apartment building.

Plant flowers in neat rows to form a fan shape. Use a triangular flower bed to alternate rows of colors, making a pattern that spreads out like a fan. Create fun patterns such as this outside a retail shop or in a child's play area. Use one kind of flower, but two distinct colors, for the fan shape.

Incorporate garden art objects. Use a bird bath or a concrete statue at the center of large triangle flower bed. Plant lots of climbing vines at the center section to climb on the bird bath or statue. Add ground cover and shorter vines to cover the rest of the trianglular space. Place concrete planters of flowers spaced evenly among the shorter vines. Use identical planters, so the triangle bed looks like a well-organized garden from every angle.
