'Stardust' is a mat-forming, succulent, evergreen perennial with linear, fleshy, dark grey-green leaves and, from early summer into autumn, solitary, violet-blue flowers with white centres.
Seeds should be sown in a fine, sandy soil at 65-75 degrees. A commercial cactus potting mix with the larger debris strained out is ideal. Flatten out the soil and put a thin layer of loose soil above it. Sow the seeds on the surface. Mist the soil to keep it moist and cover with clear plastic. The soil should not be allowed to dry out while the plants are still seedlings. Use a mister if the soil does get dry. Place the seedlings in bright light. Placing the seedlings just a few inches from a fluorescent bulb is ideal, although natural light works too. Be sure to air out the seedlings once a day for best results. If germination procrastinates, refrigerate for 3-4 weeks and return to warmth.
