Select Coleus varieties for the long haul. Coleus often last as perennials in Florida if the winters are not extreme. One key is to grow varieties that are extremely late to flower. The second key is to find varieties that are not susceptible to leaf diseases. The leaf disease that is a problem is Downy Mildew. Chartreuse or yellow leaved varieties are most susceptible.
We sell varieties at The Home Depot in gallon pots that are late to bloom and disease resistant with vibrant colors. Below are just a few of our best varieties. All our varieties are suited to sun or shade.
Coleus Rustic Orange and Finger Paint in production.
Coleus Finger Paint sports red, yellow and a mosaic of red & yellow. Pinch out the color you desire the least of and customize the color patterns of your Finger Paint. The yellow in Finger Paint is not prone to disease.
Coleus Mariposa is a very large growing big leaved coleus. Pinch Mariposa before it gets too big and falls over in a windstorm. Mariposa becomes variegated in the fall with wide hot pink edges against dark red centers.
Coleus Peter's Wonder is very strong and very popular too.
Defiance is one of the all time best performing mildew resistant gold edged reds.
This is the new Versa Crimson Gold that is also downy mildew resistant. It flowers quicker than the vigorous growers we supply to The Home Depot but pinching the flowers is not much more trouble than pinching non-flowering tips of the vigorous varieties to keep them compact so the windstorms don't topple them. This Versa series upgrades the quick blooming and mildew prone Wizard Coleus series that has been so widely used for many years. We are trialing the other colors of Versa to see if they are mildew resistant too. We sure need a chartreuse that won't get mildew like the one pictured at the top of the page. The Versa implies versatility for use in sun or shade. When pinching you should not remove more than 1/3 the length of any of the stems of the plant. Pinch often and you will enjoy your coleus more. Experiment with staggering where and when you pinch parts of a plant so it always looks full and stays relatively compact and windstorm resistant. Another problem with coleus is that they eventually succumb to nematodes, microscopic parasitic root feeding worms. You can grow coleus in containers and they will remain nematode free. A good deterrent in your flower beds is organic soil. The good bugs (bacteria, fungus and other microorganisms) in organic soils kill nematodes. Consider growing coleus and other annuals in our Pot-in-Pot method and you will be able to keep them longer and lift them to protect from frost or while mulching and getting rid of weeds in the garden. With this method you can better focus the water and fertilizer to the plant and waste much less while saving time.
Growing coleus in containers is very popular. Here is a window box with gallon containers featuring Coleus Peter's Wonder, Sweet Potato Vine, a great Spiller, and the most beautiful and popular grass, Red Fountain Grass which is also commonly called Purple Fountain Grass. Pennesetum setaceum 'Rubrum'. Such a Thriller!
