*Leuenbergerioideae and Maihuenioideae are basal cactus lineages that diverged before the main groups (Opuntioideae and Cactoideae). They retain more “ancestral” traits (persistent leaves, tree/shrub habit), distinct from most other cacti.
❄️ Climate / hardiness traits:
HARDY
– tolerates short frost (−5 °C or lower)
SEMI-HARDY
– tolerates light and short frost (0 °C to −5 °C)
SENSITIVE
– cannot tolerate frost; must be kept above 5–10 °C
TROPICAL
– requires warm conditions year-round
HEAT-TOLERANT
– tolerates extreme sun and desert heat
🌍 Growth type:
GLOBULAR – spherical form
COLUMNAR – tall column cactus
SLOW-GROWING
FAST-GROWING
DWARF - very small cacti.
GIANT - very large cacti.
🌵Conservation / availability:
RARE
- naturally rare or limited distribution, very limited habitat or cultivation
ENDANGERED
– officially threatened or habitat decline
