The nursery trade continually comes up with new and better varieties of some of your old favorites. Sometimes the plants are more disease resistant or drought tolerant. Sometimes the colors are brand new and the blooms long-lasting. Each year Linnaeus Teaching Garden features one annual in its trial beds so that gardeners can see new and different varieties and follow how well they do in Tulsa.

Our 2019 variety will be chosen and planted sometime in May.

Here’s a look at 2018’s featured plant, sun coleus.

Hot New Annuals for 2018 – Sun ColeuS

Traditionally gardeners have used coleus with its stunning foliage to brighten shady areas. However, in recent years growers have developed new varieties of coleus that grow well in medium shade to full sun. In 2018 Linneaus Teaching Garden spotlighted coleus that thrive in the sun.

Sun coleus come in a wide range of colors with both single and multi-colored varieties. Most are upright, but trailing varieties are also available. These tend to have smaller leaves and can be used in containers or to soften the front edge of a bed.

Sun coleus do require frequent watering, especially in windy conditions. Keep the soil moist, but not saturated, and you can enjoy their colorful foliage all summer until late fall.

Our hot new annuals are displayed in 15 trial beds located along the drive that parallels the entry walkway.
