Adromischus cristatus - Crinkle Leaf Plant
Long emerald green leaves with wavy ends. This one grows on the faster side for Adromischus, but it's still fairly slow growing and is great if you are short on space. You can propagate it by leaf - just stick the end of the leaf that was attached to the plant into some soil.
Your plant will be similar to the one in the photos.
Part sun, protect from hot afternoon sun
Let dry between watering, water deeply
Not as picky about soil
Ships in a plastic pot with soil.
Adromischus are fairly easy plants that generally grow slowly and stay compact, so its easy to have a big collection in a small space. Plant them in well draining soil and water them after they dry out. They like lots of sun, and develop their best colors if they have enough. Some types develop a thick base known as a caudex as they age. All can be propagated easily from the leaves, just stick the end that was attached to the stem into soil and wait. It can take quite a long time, but eventually little leaves will pop up and you will have a new plant. They grow long, sometimes twisty flower stems with tiny flowers.
