The Clog or Goldfish Plant, Nematanthus gregarius, had been successfully grown as a stopped pot plant at Kinsealy in 8–12 month schedules.
Then during 1983–85 3 species of Nematanthus and 23 cultivars were assessed unstopped as mini-pot plants using some 6 cuttings per pot.
Results showed that plants propagated from late spring to early autumn were saleable as neat mini-flowering plants within 3 months.
Those propagated under low light conditions took some 6 months to mature.
Shoot-tipping reduced plant height and spread effectively when growing conditions were poor, but it also reduced flower number.
Cultivar recommendations are made according to flowering season.
