Honeysong pink aster (aster novae-angliae ‘honeysong pink’) combined with Russian sage (perovskia atriplicifolia) works well in cut floral arrangements.

Bring a bit of your fall garden indoors. Many of your fall flowering perennials make great cut flowers to enjoy in arrangements for your home and bouquets to share with others.

Harvest your flowers early in the morning whenever possible. This is when they are fully hydrated, helping to extend their vase life. Early evening is the next best time, but any time you need to cut your flowers will work.

Take along a clean bucket of water and a sharp pair of bypass pruners or snips to the garden. Immediately place the flowers in the water to help prolong their vase life.

Picking flowers at the right stage for the variety you are cutting is important to ensure the flowers showcase their best display and will last the longest in your arrangements. In general, spike-type flowers should be harvested when one-fourth to one-half of the individual flowers on the spike are open. Daisy-type flowers like rudbeckias, coneflowers, heliopsis and helenium are harvested when the flowers are fully open.

Asters and golden rods make a great combination in the garden as well as a vase. Harvest the golden rod as soon as the flower color is visible with half of the individual flowers in the cluster open. Look for and pick asters when one-fourth of the flowers in the cluster are open to enjoy them for as many as seven to 12 days.

The native agastache, you may know as lavender or anise hyssop, is a pollinator favorite and makes an excellent addition to flower arrangements. Wait for one-half to two-thirds of the flowers on the spike to open before picking. With proper harvesting and care, these flowers can last six to 10 days in your arrangement.

Watch as the individual flowers on the liatris spike open from the top down. Harvest these when less than half of the flowers at the top of the spike are open and the remainder are in bud.

Once rudbeckias and coneflowers shed their petals, which are actually non-fertile ray flowers, the remaining seed heads still make an attractive addition to fall bouquets. Don’t overlook the wispy seed heads and foliage of ornamental and native grasses growing in the garden. These can be harvested at any time after the seed head emerges and last about a week.

Consider adding a few seed pods for added fall flare in your bouquets. The pods of native baptisia and milkweed as well as Siberian iris are a few to try.

Condition fresh flowers before arranging to further extend their vase life. Set the flowers in tepid water and place them in a cool place out of direct sunlight for at least several hours and preferably overnight before arranging.

Recut the stems on a 45-degree angle to the desired length when creating your arrangements. The angled cut prevents stems from sitting flat on the bottom of the vase, exposing more surface area to absorb water. Remove the lower leaves that would otherwise end up submerged in the water in the vase. Foliage in the water encourages microbial growth that can shorten the vase life of your cut flowers.

Always use a clean vase filled with fresh water. Add a floral preservative to the water to further extend the vase life of your flowers. Change the water often to keep flowers looking good for as long as possible. Remove individual flower stems as they fade and rearrange the remaining ones that still look fresh. Recut the stems as needed to keep the flowers absorbing water and lasting longer.

Add your own perennial flower favorites and evaluate how they perform as cut flowers. Make a few notes on those that worked well and do a bit of research to improve the vase life of those that did not. Even a short-lived arrangement will generate a smile and brighten your mood when bringing a bit of your garden indoors.
