Adenium, also referred to as Desert Rose or Sabi Star, is a succulent shrub that grows up to 5 feet in height. Relative of the plumeria, adeniums produce breath-taking, painted blooms in shades of red, pink and white amidst glossy, dark green foliage. Set on pachycaul, or swollen, gray branches, the glorious adenium blooms are an excellent addition to rock gardens or potted and used as a focal point in courtyards. Adeniums thrive in hot temperatures that remain below 100 degrees Fahrenheit and can survive winters when grown in containers that are properly maintained and stored.
Moisten two sheets of paper towel and place on a plate.
Lay 1 to 2 seeds between paper towel sheets, and soak for 2 to 4 hours. Do not allow the paper towel to dry out during this time.
Fill pot with cactus potting mix and thoroughly soak the mix with water. Allow water to drain completely from the pot before planting the adenium seed.
Insert seed, horizontally, into the soil, no deeper than 1/4 of an inch, then cover lightly with moistened soil.
Place pot in a location that gets direct sunlight, at least in the morning hours. You can also use a growing light, if you do not have a location that offers enough sunlight.
Keep soil moist, but not soggy, during germination and spray 1 to 2 times a day with a liquid fertilizer such as Spray-N-Grow until seeds sprout. Germination takes three to 20 days.
Transfer adenium seedlings to a larger container once they have sprouted and shed the seed coating. Continue repotting adeniums into larger containers as they grow to prevent interruption in growth.
Fertilize adeniums every other week after germination.
