Give this plant bright, indirect light indoors or outdoors place it in part shade (morning sun for 4-6 hours).

Keep the soil consistently moist but not soggy.

Keep your plant around high-humidity

If this plant is grown outdoors as a groundcover, it will produce flowers in the fall.

Fall blooming outdoors

Fertilize every two weeks during the growing season (spring and summer) by diluting a liquid fertilizer by half strength.  Let the plant rest in the fall and winter. If the leaves get too droopy, increase the fertilizer a bit.

When receiving the plant, do not repot immediately but wait at least 6-12 months or if the roots are beginning to get crowded and growing through the drainage holes.
Repot in the spring, using a 2"" bigger pot to keep the roots drier. Use a well-draining indoor potting mix with perlite.
Water your plant in the old pot before transferring over and let it sit an hour. Place a piece of screening at the bottom of the container over the drainage hole to the soil and allow it to drain. Add soil to the bottom to elevate the root ball. Lift the plant and release the roots against the existing planter. Use a clean knife or garden trowel to wedge between the pot and the soil to loosen.
Inspect the root ball. Notice if there are any dead or rotting roots and trim off with sterile pruners. If the plant is rootbound, cut through the roots to alleviate continued encircling.
Ensure the plant is sitting about 1"" below the edge of the pot to avoid water spillage. Add more soil and backfill around the sides by tamping down. Fill up to the soil line but not over.
Water thoroughly, leaving the soil damp but not soggy. If settling occurs, add more soil. 

Pinch back the long branches to encourage bushy growth.

To propagate this plant during the growing season:
Take a 3-4 inch stem cutting at the tip of a branch.
Place the stems in rooting hormone and place the stem down into the rooting medium.
Tamp the soil around the stem gently and mist the soil.
Check the moisture of the soil each day.
Place the cuttings in bright, indirect light.
After the roots are six weeks old, they should be ready to transfer into the garden or container garden in part shade outdoors or an indoor plant. Transition the cuttings a few hours per day to help them acclimate to the new environment.
