Find a Solution: Gardening Questions

Darin Engh with Engh Gardens helps answer three big questions for planting flowers; what’s an annual, perennial, and biennial?


Annual plants complete their entire life cycle, from germination to seed formation, in a single season. This speed makes them ideal for many garden situations, especially if you want an instant garden. This tends to make them the showgirls of the flowering world, doing it up like nobody’s business before the lights go out.

Some of Darin Engh’s favorite annuals are Supertunia , Verbena, Impatiens, Cosmos, Nemesia, Osteospermum, Phlox , Cineraria.


Biennial plants complete their life cycle in two years. They grow leaves, generally in the form of a rosette or mound,during the first season. These leaves overwinter, and then early in the following spring, the plant sends up a flower stalk and dies.

Some of Darin Engh’s favorite biennials are Pansy, Snapdragon, Hollyhock, Dianthus, and Foxgloves


Perennials go the distance, coming back for more every year, often bigger and badder than ever. Most flowering perennials are tough, sturdy plants that tolerate a wide range of environmental conditions, are resistant to pests and diseases, and require very little coddling. You can divide them up to make more plants, like daisy and daylily. Perennials live more than one year.

Some of Darin Engh’s favorite perennials are Gaura, heliopsis, Scabiosa, Heuchera, Lamium, Daisy, Lysimachia, and Oxalis.
