My Flower Bed

My Flower Bed

Well I finally started gardeing again.  I decided to plant the flower bed in my front yard. *Again* Sigh. I  planted some Easter Lillies in this bed back in May but to no avail. They all died! Some of my friends offer me free clippings from their gardens. I'm all about free so I decided to try again. So far so good. They are going on their second week they are still green! 
Here's what's in the bed

The last picture is of my yucca plant. I have no idea what the names of above the plants are. If you have any idea please let me know! Do you have any garden tips, ticks, advice?I'd love to hear them!
