Topic: Groundcovers, Shade Tolerant
Title: Salt-tolerant groundcover for shade with no water supply
Answered by: Nan Hampton
QUESTION:
We have a home in Neptune Beach (Jacksonville) Florida (NE Florida). We have a large area outside our ground floor master bedroom that is completely covered (there is a large solid deck above it). It has total shade and no watering system. Right now it is just dirt. We would like to be able to make it look more inviting and beautiful. Instead of using pavers or stones, can we use a ground cover and/or plantings? Is that possible? If so, what would you suggest that would thrive? We are also 2 houses from the ocean so the plantings would need to be somewhat salt resistant? Any help would be greatly appreciated to make this area attractive and welcoming. Best Regards, PamANSWER:
That's really a triple whammy—salt tolerant, no moisture and completely shaded! I could find you lots of beach groundcover (salt tolerant) that grow well in full sun, but plants that thrive in full shade is the hard part! Here, however, are a few that could work.
- Phyla nodiflora (Texas frogfruit) grows well in part shade and sun. Here is more information from Florida Native Plant Society.
- Salvia coccinea (Scarlet sage) grows in shade, part shade and sun. Here's more information from the Florida Native Plant Society.
- Pachysandra procumbens (Allegheny spurge) is evergreen and grows in shade and part shade. Here is more information from Floridata and Missouri Botanical Garden. The Growing Place says that it is able to handle "environmental salt".
- Pteridium aquilinum (Western bracken fern) grows in shade or part shade. Here is more information from Floridata. It is listed as NOT salt tolerant by the Florida Native Plant Society.
There are two evergreen vines that are moderately salt tolerant and will function as groundcovers.
- Gelsemium sempervirens (Carolina jessamine) grows in part shade and sun. Here is more information from Floridata and Florida Native Plant Society. It is listed as moderately salt tolerant by University of Georgia Marine Extension Service CoastScapes.
- Lonicera sempervirens (Coral honeysuckle) grows in part shade and sun and is listed as moderately salt tolerant by University of Georgia Marine Extension Service CoastScapes.
If you would like to put some small shrubs under your deck, Morella cerifera [synonym = Myrica cerifera] (Wax myrtle) is listed by University of Georgia Marine Extension Service CoastScapes as being highly salt tolerant. There are dwarf cultivars available and they will do well in part shade.
All of the plants above will grow in relatively dry conditions, but they are going to need frequent watering to become established. You could do this by hand or with water sprinklers attached to hoses.
