I'm afraid there's none that is large enough to give as wedding favours in that short time. At best you'd probably produce seedlings that are too fragile at only 2 weeks. Most plants need 2 weekds to germinate.

My suggestions it to head to the garden centre to purchase young plants. Or to get someone to share plants by division which will provide a good enough size - or go to garden to look for young seedlings for transplanting.
