Hello Mr. Botanist aka @ctrl-alt-nwo :)
Impatiens hawkeri, the New Guinea impatiens, is a species of flowering plant in the family Balsaminaceae. It is native to Papua New Guinea and the Solomon Islands. It has been bred and hybridized in cultivation to produce a line of garden plants.
The plants have a neat, mounded shape, to a height of 20 to 30 cm. They are perfect for containers - in a big pot, three plants will grow together to form an impressive mass. They are self-cleaning - so no dead-heading is required.
If they are grown in a pot set on paving, wooden decking or tiles, it is advisable to sweep away fallen flowers regularly, as these can adhere annoyingly to the surface after a while.
Colors range from bright hot colors of reds and oranges, to cooler hues of white, pinks, cerise and purples. Some of them have interesting foliage as well.
Note that when growing plants in outdoor containers and baskets, they may require more frequent watering than they would in the yard or garden.
