. Table 1. Succulent and cactus plant material evaluated for variation in temperature effects [10 to 25 °C (50.0 to 77.0 °F)] on leaf/tubercle-unfolding rate per day and the indigenous habitat that each plant is from. Nine succulent species/cultivars with
; however, this is not the case. Erwin et al. (p. 65) grew 17 succulents and one cactus species at temperatures ranging from 50-82 o F and found that optimal temperatures for leaf/tubercle unfolding rate ranged from 61-72 o F to ≥82 o F for different
