tarev: Very good advice you have offered. I like the idea of shallow pots for plants with shallow roots. When I purchase a new plant of any type or transplant any plant to a new container I always use the garden hose and gently spray off all of the old potting medium and re-plant in fresh medium ... better to be safe than sorry. A few years ago I was at Home Depot and got to talking to a commercial nursery person (who was checking their inventory that had been delivered to the store) and learned that most nurseries use a very heavy, water retentive soil to keep the plants alive for the time they may sit on the shelves at the stores. If the consumer leaves the plant in that soil and waters a lot, the plant will surely not be happy unless it's a bog plant.
Here's the link to the All Things Plants Database where you can see Jade photo's with those pretty flowers:
