Rain Garden: Veronicastrum virginicum, eupatorium, and calamagrostis 'Karl Foerster'
Rain Gardens: A solution to moisture, poor drainage problems and increased precipitation
The idea behind rain gardens is to collect precipitation runoff from impervious surfaces and use it to help sustain nearby plantings that serve to absorb and purify excess water before it is slowly reabsorbed into our groundwater. The concept is surprisingly simple: a depression is created in the landscape where the plants are placed, and water from rooftops, driveways, walkways, etc. is collected and redirected to these depressions, typically with downspouts and other types of piping, or a river of rock leading to the garden; this will also help to prevent erosion in the garden when heavy rainfall occurs.

Hot and Dry Gardens: Beautifying a Barren Landscape
Lack of rainfall creates another set of challenges. These parched areas are just plain tough to manage when it comes to plantings. They are dry, sometimes gravely/sandy, and perhaps difficult to access on a regular basis. But there is a solution: plant a dry garden!
By selecting plants that, when mature, can easily tolerate these rather austere conditions, you’ll have a beautifully landscaped area rather than an aggravation. They do very well in regular soil, only require watering during especially hot/dry spells, and generally do not require much for fertilizer or other care, aside from maybe scratching in some compost or granular, slow-release fertilizer upon planting. Don’t forget to water perennials during the first season of establishment.

And yet there is still another condition that must be considered when adding new plants to the landscape. While some plants may be tolerant of wet soils, they might not tolerate humidity and heat very well, especially when they take place concurrently.
