Mesembryanthemum haeckelianum, formerly known as Aptenia haeckeliana or Platythyra haeckeliana, is a succulent plant with 4-angled stems and flat, green leaves. It grows flat onto the ground. Flowers are pale yellow and appear in spring and summer.
USDA hardiness zones 8a to 11b: from 10 °F (−12.2 °C) to 50 °F (+10 °C).
How to Grow and Care
Water Aptenia only when the soil is completely dry and then provide enough to drench the soil to a depth of about 6 inches (15 cm). To check for dryness, poke your finger into the soil. Never water if the soil feels damp or cool, as Aptenia, like all succulents, is prone to rot in soggy, waterlogged soil. Water Aptenia lightly during the winter if the leaves begin to look shriveled. Provide only enough water to moisten the soil as the plant deteriorates quickly in cool, damp soil.
Withhold fertilizer, which isn't needed and often results in a weak, floppy plant. Trim the plant as needed throughout the growing season, using pruners or garden shears to keep the plant tidy. Pot the plant and bring it indoors for the winter when nighttime temperatures drop below 50 °F (10 °C).
