Cultivated Plants in the Tucson Mountains. The vegetative and flowering cycles of more than 200 plant taxa have been recorded over the past two decades in order to determine their seasonality. Rather little is known about the specific triggers to leafing and flowering of desert plants. It is widely assumed from empirical observations that most are opportunistic and respond primarily to rain, but statistical analysis shows a number of unexpected differences and complexities. Horticulturists can use these data to plan seasonal flower displays in desert climates.
Scientists can use the phenology and weather data to search for the triggers of phenological events.
Propagation of Sonoran Region Plants. Most of the plants used to landscape ASDM exhibits are not commonly cultivated, so little is known about their propagation or cultural needs. A database contains detailed records of all or our attempts to grow regional plants from seeds or cuttings. Management of Cactus Borers in Cultivated Cacti. While they are usually not a threat to wild cactus populations, they can devastate cultivated collections.
