Home Depot has return policy on sold potted plants - 1 year, with store refund issued for the paid amount. If you bought bulbs and planted them - there is no refund. You only could return bulbs in unopened package. Just wait a little bit longer, may be they just need more time.

The bulbs usually don't emerge until it begins to warm up and stay warmer for a little while. I'm in Zone 7a and my Callas and tuberoses have only been peeping out for a couple of weeks. Clematis are different to me than any other plant. I've planted about 7 or 8 and finally got 3 to grow. One I planted last year is just about a foot long and my other two have been blooming for weeks already. It takes them sometimes 2 or more years to really get to going. If it doesn't come up at all that will be different. For more information on bulbs there is a Bulb Forum on GW which would be really helpful to you.

Oh, Thank you both so much for all the info. I will definitely go and check it out. And I'll be a bit more patient. I didn't know HD doesn't give refunds for bulbs. Rats, but only if they don't come up. I'll keep hoping!
