If you do choose to try your hand at growing Uebelmannia cacti, you can tend to them year-round indoors, where they’ll grow slowly, eventually reaching up to 3 feet over time when given the proper conditions.
Blooming season: Early Summer to Late Summer. Fruits: Ovoid, yellow, to 4 mm in diameter.
Uebelmannia buiningii 10 seeds Cacti Brazil – African Seeds.
The combination of low reproductive activity with gametophytic incompatibility, together with the reduced number of individuals in a population and low number of populations, makes the endemic cactus U. buiningii a critically endangered species.
Origin. Uebelmannia buiningii is endemic to Brazil. Its natural habitat is dry savanna.
Make sure to keep well watered, as well, and give them lots of light. Their roots need some space and really good drainage and keep an eye out for common pests that can damage them.
WATERING: From Spring and Summer water well allowing the soil in the pot to dry out before watering again. In Winter these cacti do not like to be kept totally dry for very long periods and I water my Uebelmannia once every 6 weeks.
Habitat and Ecology: Uebelmannia buiningii grows in south-eastern campo rupestre (Serra Negra) on slabs of quartzitic rock amongst quartz gravel.
Description: Uebelmannia buiningii is the most diminutive and also the most floriferous of the genus. It is a very pretty plant but tricky to cultivate and almost always grown grafted onto columnar cacti.
Uebelmannia buiningii has day-opening flowers that last three days. Anthesis begins at 7 a.m. and flowers stay open until closing time at 5 p.m., and this process is repeated over three days, with the flowers closing completely and wilting on the last day.
Blooming season: Early Summer to Late Summer.
