Hardiness of a plant may be divided into two categories: tender, and hardy. Tender plants are those killed by freezing temperatures, while hardy plants survive freezing—at least down to certain temperatures, depending on the plant. "Half-hardy" is a term used sometimes in horticulture to describe bedding plants
Hardiness may refer to: Hardiness (plants), the ability of plants to survive adverse growing conditions Hardiness zone, area in which a category of plants is capable of growing, as defined by the minimum temperature of that area; Psychological resilience or mental resilience, positive capacity of people to cope with stress and catastrophe
A plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 to 40 °F (−1.1 to 4.4 °C). Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale.
The plant is readily grown from seeds, which are abundant (100 to 300 in each fruit), but with low germination rates, requiring thousands of seeds to sow a hectare. [2] Plants grown from year-old stem cuttings will flower early and yield well, but are less vigorous than those grown from seed.

Plant growth and development are mediated by specific plant hormones and plant growth regulators (PGRs) (Ross et al. 1983). [9] Endogenous hormone levels are influenced by plant age, cold hardiness, dormancy, and other metabolic conditions; photoperiod, drought, temperature, and other external environmental conditions; and exogenous sources of ...
