This succulent has narrow stems, and small growths along the edges of the leaves.
Can anybody tell me what succulent it is?
This is Kalanchoe daigremontiana tubifolia (Mother of Thousands) plant. You have the photograph of a beautiful specimen.
One thing that makes it unique among all succulents is that it has little "plantlets" along the leaves. They are exact duplicates of the original plant. As they grow, they drop off into the soil and root themselves. You can also pop them off and root them separately if you'd like. This process is part of where it got the nickname "Mother of Thousands." Some even call it "Mother of Millions."
It grows up to 2-1/2 ft (75 cm) tall.
it originated in Madagascar, so it likes the heat. In fact, it will tolerate even extreme heat, but frost will kill it quickly. It's hardy in zones 9-11, so in most areas it grows better as a houseplant. Indoors it prefers average room temperatures of 60-75°F/16-24°C. Keep it in bright to full sun outdoors, or a sunny window inside. You can also alternate between outside and inside as the weather changes.
When potted, it grows best in soil made for cactus and other succulents. Water it thoroughly, and let the top 2 inches or so dry out before watering again. In the winter, cut back on watering, but never let the soil completely dry out.
It's important to note that this is a very poisonous plant when ingested. All parts are poisonous, to both pets and children.
The flowers are unusual too,
