Plectranthus australis is a member of the mint family, and it's not an ivy, which is rather odd, since it's called Swedish Ivy. It's actually related to coleus. It needs direct, but filtered light, or indirect bright light.

One of the major things I learned in growing a nice plant, is to pinch it back on a regular basis so that it becomes nice and full. It also needs to be turned daily so that all sides receive equal sunlight. I hung mine on the porch in the warm weather where it really did well in the fresh air and sunlight. Be sure you give it good light and air circulation.

Swedish Ivy do tend to get woody as they get older and eventually need to be replaced. Take a nice section of cutting and root it in water, and you will have a young plant to start over with. They need to be kept evenly moist, but not too dry or wet. If they start looking spindly you need to move it to a sunnier spot, and keep pinching it back to help promote new growth. Again, the pinching is a crucial thing in keeping your Swedish Ivy looking nice.
