I've seen this beautiful specimen online once before while browsing interesting-looking plants, but have forgotten its name. This one I purchased about three weeks back. What is its name and how do growers usually care for it?
This is a houseleek - you can read more about it here. It is quite varied in its appearance as a group of plants, often with a pointed tip to the leaf and with red tinge to the extremity of the leaf. Yours is a round leaf type with little or no red. Water sparingly, provide sharp drainage and give good light.
