A first flower bed does not need a complicated shape. It needs a place where you can reach plants without repeatedly stepping on the growing soil.
Plan from the edge inward
Mark out the bed with a hose or string before digging. Check whether you can comfortably reach its center from a path or lawn. Adjust the width to your reach rather than copying a photograph.
Observe sunlight and drainage after rain. Do not choose flowers first and then try to force the ground to meet every conflicting requirement. Remove persistent weeds thoughtfully and identify anything unfamiliar before spreading fragments through the bed.
Start with a readable planting
Choose a small number of suitable varieties, using mature size to plan spacing. Repeat plants where possible so you can compare their growth. A bed with twenty unrelated species gives a beginner twenty sets of care requirements at once.
Water new plants at the root zone and keep mulch away from their crowns. Leave room to inspect the ground between them as they establish. Photograph the bed from the same place occasionally. You will soon see which spaces fill, where a taller plant casts shade, and what needs adjusting before buying more plants to solve a problem that is really about layout.
