Yellow Slipper Flower
Repot it to a container about 50% wider than its current pot. Repot gently to avoid letting the soil ball break apart.
Use well-draining soil. I use a mix of 1 part coco fiber to 1 part perlite (use small- or medium-grade perlite, not coarse-grade). An alternate mix is 2 parts quality potting soil to 1 part perlite.
Watering -- Aim to keep the soil evenly moist (but not constantly saturated). Don't let it dry out.
Climate - The Slipper Flower prefers mild temperatures and cool nights. It might not thrive if temperatures regularly get above 84°F (28°C), especially if nights are above 65°F (18°C). I don't think it can handle frost. It prefers dappled sun or bright shade, and needs protection from strong afternoon sun. Over about 40% humidity is best. If it seems to suffer from low humidity indoors, consider using an ultrasonic humidifier, sold at home improvement stores or some thrift shops.
Your plant was grown in filtered light, so it should be acclimated to direct sun slowly, over a period of a few weeks. Remember that this plant does not need a lot of direct sun to be happy.
The shoots may be tied to a trellis, or allowed to trail along the ground or climb over other plants. You can also grow it in a hanging planter. You may prune any shoots that grow too long. Side shoots will then sprout from the nodes below the cut, making it bushier.
Fertilizing -- Calceolaria has average fertilizing needs.
Bugs to watch for -- Aphids, spider mites. Look for any pests that can affect your other plants.
