Adromischus trigynus is a dwarf, compact succulent plant with grey-green leaves mottled and often with a purplish-maroon marginal tinge. It grows up to 1.8 inches (4.5 cm) tall and up to 5 inches (12.5 cm) in diameter. Leaves are compactly arranged, obovate to nearly orbicular, convex both above and beneath and up to 1.4 inches (3.5 cm) long. Small, white or tinged pink flowers emerge on up to 14 inches (35 cm) long stalks in late spring. They are not particularly showy.


USDA hardiness zones 9b to 10b: from 25 °F (−3.9 °C) to 40 °F (+4.4 °C).

How to Grow and Care

Many species are easy to grow in any free-draining, gritty compost. Their compact habit allows a collection to be maintained in a small space and they grow well on any sunny window ledge or the top shelf of the greenhouse. Water mostly from spring to fall and let them dry out between waterings. Adromischus tolerates cool, frost-free conditions during the winter if kept dry. It is as well to keep water off the foliage during the winter. Mealybugs and vine weevils can be discouraged with a systemic insecticide.

Adromischus can be propagated from a single leaf, which should be placed against the side of the pot so that the stem end is just touching the compost. Some species drop their leaves easily and although each leaf will form a new plant it can be a challenge to grow a large specimen. In other cases, leaves for propagation must be carefully detached with a sharp knife.

About Adromischus Maculatus

  • Their scientific name comes from Greek and describes them perfectly. While the word “adrosmischos” means “thick stems”, “maculatus” is the specific epithet that means “spotted”.
  • They are quite fragile, so you should avoid touching them very often. Moreover, with their shallow root system, these plants are susceptible to root rot.
  • Calico Hearts succulents enjoy warm and dry environments. Protect them from freezing temperatures and cold drafts, as they will not survive in cooler conditions.
  • In their natural habitat, these plants are used to semi-arid climates. They are very tolerant of drought and will not respond well to over-watering.
  • They are easy-going plants that prefer bright light, but will also do well in full sun, light shade, or partial shade. The best time of their life is during the summer.
  • Like all succulents, A. Maculatus requires a well-draining potting soil that is suitable for cacti and succulents. Depending on the growing conditions, they may need occasional fertilizing.
  • Their foliage will be visited by intruders from time to time. Keep your Calico Hearts clean and watch out for pests while caring for them.
  • These succulents have no popular use in traditional medicine or other purposes. They can be pretty toxic to pets and humans if ingested, so make sure you place them in a “secret” location.
