It grows in an upright, clustering habit, forming a compact sculptural mound. The leaves are fleshy, rounded, and stacked closely together in a dense, almost geometric pattern, with a bright green, waxy appearance that stays attractive year-round. A single plant gradually clusters and fills in, becoming a full specimen over time.
It produces small cheerful blooms typical of the Portulaca genus, adding seasonal color to its form. One of its most useful traits is that it shows you when it needs water through gentle wilting. Note that it does produce pollen and allergens, so it is worth knowing if you have sensitivities.
You can leave it up to ten days without water. Move it outside in summer to soak up natural sun, but always shelter it from rain, as excess moisture causes rot. Keep it on a high shelf well out of reach of cats, dogs, and toddlers. Its rarity, upright clustering form, and Hawaiian origin make it a conversation piece in any succulent collection.
Water it every 10 to 14 days, allowing the soil to dry completely between waterings.
Portulaca Molokiniensis does best in a gritty, fast-draining cactus and succulent mix amended with extra perlite.
It prefers temperatures between 65 and 95 degrees Fahrenheit and is not frost hardy.
Portulaca Molokiniensis is a slow to moderate grower that benefits from diluted balanced fertilizer once monthly during spring and summer.
It is hardy in USDA zones 9 through 11, where temperatures rarely drop below 20 degrees Fahrenheit. It grows outdoors year-round in Hawaii, Florida, Southern California, coastal and Southern Texas, Arizona, Nevada, Louisiana, Alabama, Mississippi, Georgia, and South Carolina.
