This form of micranthum grows and flowers more easily than the type. It does not require as much of a winter chill to set buds. We grow them along with out Maudiae type Paphs. We do give them a better drained potting mix as this species does not like wet feet. Our care page has plenty of cultural tips to help you grow better Paphs.
