String of beads

Triggered by the most thoughtful surprise gift from Husband, I am researching plants to put in the front south-facing flowerbeds. The tulips and grape hyacinth were beautiful and lush in the spring, but now there is nothing but dirt. After the a failed hydrangea experiment, I am thinking of using lavender as the main focus shrub. MIL has also generously offered a harvest from her flowerbeds.
I love our neighbor's yard. Even though it is completely under kept, the plants fascinate me, and it's actually part of my inspiration. (Maybe it's the fact that they never do anything to it and the flowers and plants are thriving that excites me.) The plan so far includes lavender, daisies and ground-cover succulents, and enchanting flowers like the echinops.
My search for plants lead me to the little number pictured above, called String of Beads (Senecio). I am officially coveting this little plant. While I first though I would put it in a bed that drops off so it could hang over next to our driveway, the plant is actually toxic when ingested. It sounds scary, but then again, people keep lilies which are toxic as well, especially to cats. I wouldn't think of planting this in reach of animals or small children, but I definitely have plenty of unreachable spots for a pot in the house. Is it worth it? . . .
