"Easy" Cut Flowers for North Florida Gardens

David A. Dinkins, County Extension Director
Bradford County Cooperative Extension Service

Cut flowers are experiencing increased popularity among gardeners and home decorators throughout the United States. Due to this increased interest, county extension faculty and master gardeners have conducted cut flower field trials in several locations throughout north Florida. Some of the counties conducting these trials include Baker, Bradford, Columbia (Research Center), Duval, Santa Rosa and Taylor.

This publication provides a listing of cut flower species and cultivars that are relatively "easy" to grow in north Florida.

Cut Flower Species And Cultivars Showing Good Performance in
Various Demonstration Trials in North Florida

Botanical Name  Common Name  Cultivar  Field Notes
Ageratum houstonianum Blue Flossflower Blue Horizon Spring planted. Flowered for 2 months, with peak in June. Heavy production, but 12-inch stems were shorter than desired.
Ammi majus False Queen Anne's Lace   Spring planted. Flowered heavily four weeks, mostly in May. A vigorous grower that produced 5 inch flower clusters of 32-inch stems.
Antirrhinum majus Snapdragon  Rocket Mixed Fall planted. Long flower spikes on 26 inch stems during spring. Caterpillars sometimes infested buds and flowers.
Asclepias tuberosa Butterfly Weed   Direct seeded during the spring. Flowered on 20-inch stems and was very heat tolerant.
Caryopteris incana Blue Spiraea Blue Mist Spring planted. The most surprising of all the trials. It flowered consistently on 20-inch stems. The unusual flower arrangement could make it a unique floral display.
Celosia argentea spicata Spired Celosia 

Flamingo; Feather Pink; Feather Purple

Outstanding performers. Both cultivars flowered for 3 months on Flamingo 36-inch stems. Flower heads are  small, and florists considered them as "filler" material. Spring planted.
Celosia plumosa Plumed Celosia Century Mixed Spring planted and very heat tolerant.
    Century Cream Flowering occurred during the entire summer. Flower heads were large, but stems averaged only 16  inches in length. Most cultivars exhibited increased length when planted in late spring and early summer.
Celosia spp.   Cramer's Amazon   
Delphinium sp. Delphinium Pacific Giants; Mix; Magic Fountains  Both cultivars of Delphinium were fall planted and flowered well during April and May. The Pacific Mix Giant cultivar was very productive, stems were too large for use by local florists.
Dianthus barbatue Sweet William Tall Double Mix Fall planted Dianthus was productive, but succumbed to heat in early May.  Stem length averaged 16-inches.
Eustoma grandiflorum Lisianthus Echo Blue; Echo Mixed; Heidi Deep Blue; Heidi Pink Rim All cultivars of Lisianthus performed well. "Echo Blue" was the most popular cultivar  produced in the trials.  Spring planted.
Gladiolus sp. Gladiolus Mixed Colors  Produced 30 inch stems and high quality flowers,  but a browning of the calyx was noted.  This condition is believed to be heat related. Spring planted corms.
Gomphrena globosa Globe Amaranth  Strawberry Fields Spring planted. Heat tolerant and  very productive. Good for both fresh and dried flowers.
Helianthus annuas Sunflower Sunbright; Velvet; Tapestry; Ring of Fire; Moulin Rouge; Valentine Spring and summer planted. Most require pinching to encourage multiple branching and smaller flowers desired by florists. Can be direct seeded or transplanted and  subsequential planting for continuous  harvest is possible.
Helichrysum bracteatum Strawflower Monstrosum; Mixed Spring planted. Flowered profusely, but the stem length was only 12 inches. Late spring or early summer plantings should be considered.
Limonium sinuatum Statice Fortress Mix; Suworowii; Bright Rose Fall planted and flowered heavily  into July. The "Fortress Mix" cultivar produced 30 inch stems. One planting of statice died due to cold injury during the winter of 1995 - 1996.
Matthiola incanata Stock Miracle White; Cheerful White Fall planted and flowered on 18- inch stems for 6 weeks during the following spring. Flower heads were extremely large, unlike any that local florists had seen before.
Monarda citriodora Lemon Mint   Spring planted. Produces tiered flower clusters on 26- inch stems.
Monarda didyma Bee Balm Panorama Spring planted. Colorful flowers on 14-inch stems.
Tagetes erecta Marigold Gold Coins Very vigorous 30 inch plants with many large blooms. Blooms up to 5 inches across and nearly as deep.
Verbens bonariensis Verbena   Spring planted. Continuous flowering during the spring and summer. Sturdy 36-inch stems do not required staking.
Zinnia elegans  Zinnia Big Red; Ruffles; Giant Blue Point; Mixed Berry's; Giant Series Spring planted. Provided continuous flowering on 18-inch stems. Cultivar selection is critical. Diseases can be a problem.  Flower petals show at temperatures below 60 degrees.
