Arctostaphylos hookeri montana is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Arctostaphylos hookeri montana is also known as:

Arctostaphylos montana | USDA symbol: ARMO7
Arctostaphylos pungens Kunth var. montana | USDA symbol: ARPUM2
Arctostaphylos pungens Kunth ssp. montana | USDA symbol: ARPUM4

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.
