This is a bi-lobed species of the Conophytum bilobum complex that comprises many morphological and geographical variants, which have previously been classified as different species in their own right. These days they are all considered to be the same species, where each form is linked to others by populations of plants with intermediate characteristics.
It is an easy plant to grow providing the watering rules are followed (see below), and it will soon form a good-sized clump. It is a winter grower, meaning it is most active from the autumn until spring and it becomes dormant in summer, however in favourable growing conditions it can be kept going over the summer too.
As with most conophytums, it requires good drainage as it can be prone to root rot. Be careful with watering, as too much can result in unsightly scars from the epidermis cracking. Water regularly in winter after the previous year’s leaves have dried up. It can be fed once or twice during the growing season with a low-nitrogen fertiliser specifically formulated for cacti and succulents, which also includes micro nutrients and trace elements. This can be diluted to half the recommended strength. Do not overfeed as this will lead to bloated growth and make the plants more susceptible to pests and diseases.
Some other growing-tips to bear in mind include keeping it cool and shaded in summer, but otherwise it needs full sun or light shade. Reportedly hardy to -2°C but ensure good ventilation. Avoid repotting too often, and it can stay in the same pot for many years.
Conophytum bilobum can be propagated by cuttings and seeds. Take cuttings from a grown-up mother plant, and note that each cutting should contain one or more heads along with a fraction of root. It is also easily propagated by seed.
