In many mountainous areas, depending on which side of the mountain range you are, you can have moist or dry climates. But cooler weather in general is in common to both. There are alpine succulents, like Delosperma, Orostachys and Sempervivum species along with cacti like Escobaria, Echinocereus and Pediocactus species. There may be some sedum species native to your area. Of course the other common climatic factor for all alpines is dry air, and windy. But most Penstemon and Agastache species will do well in dry, poor soil, and relatively hot climates.
