Impatiens are usually purchased from a nursery or as liners (small starter plants) from an online vendor. Most impatiens thrive in filtered or partial shade. Protection from the hot afternoon sun will help to maintain their colors. Some newer varieties grow well in sunny areas. Where to Plant...
Infection is distributed by thrips adults or budding of plants. Economic significance: INSV is widespread in Europe, America, Asia, and recently in Iran; in roses, this leads to reduce the quality of flowers and amount of essential oil. Disease symptoms: Disease symptoms are similar to tomato ...
Urbanization is changing the conditions in which many species live, forcing them to adjust to these novel environments. Floral size and shape are critical traits for the reproduction of plants pollinated by animals as they are involved in the attraction of pollinators and in efficient...
In Europe, a significant proportion of entomophilous alien plants are ornamentals with long flowering seasons, appealing scent or showy flowers [73] and so facilitate interactions with native bees. However, the positive effects of alien plants might be limited to generalist pollinators, and ...

After 90 days of incubation, results revealed a higher concentration of total Hg in the leaves than in the flowers or the stems. Plants that were grown in the soils with higher Hg concentrations showed significantly higher Hg uptake and translocation in the aboveground plant-biomass, and the ...
Petunia plants that experienced both competition from other plants in the container and lower irrigation rates had enhanced efficiency of flower production (i.e., more flowers per unit biomass). For Impatiens, however, the growing of single plants at "25% ETp" was plausible, but the addition ...
Visual observation of the four groups of plants at different time points suggests that in control W plants the number of open flowers is somewhat higher at later time points (T3, T4) than at the beginning of the experiment, in contrast to stressed D plants, where drought stress (T3) clearl...
