These are neat plants. They somewhat look like a mini walleriana. The flowers may be small but the plant can get about 3ft wide and about a foot tall when well grown. They can set seed in a zone 10 with out any problems for you I'm not real sure. They will be tender for you as they are for me. I grow mine in a 10inch pot in a sheltered area and it barelly survived the winter. They start by cuttings like any other bedding type though. I would grow them like you would any other balsam. A nice humusy soil in bright shade will do them just fine. I really suprised to see a company like that selling them. Hmmmm maybe my work is paying off. I would like to hear from others as well.
