This native beauty might just be the answer to your prayers if you’re looking for a low-maintenance plant that can handle whatever Mother Nature throws at it – especially if what she’s throwing is blazing sunshine and very little rain!

What Makes Nevada Rockdaisy Special?

This delightful native plant is a true survivor of the American Southwest, calling California and Nevada home. As a perennial member of the sunflower family, it brings those cheerful daisy-like blooms we all love, but with the added bonus of being perfectly adapted to harsh desert conditions.

The Nevada rockdaisy stays refreshingly compact, typically growing as a low shrub under 1.5 feet tall and never exceeding 3 feet at maturity. Its small, lobed leaves create a neat, mounded appearance that works beautifully as a groundcover or accent plant. When it blooms – primarily in spring and fall – it produces clusters of small yellow flowers with delicate white petals that seem to dance in the desert breeze.

Perityle megalocephala var. megalocephala 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. Perityle megalocephala var. megalocephala is also known as:

Laphamia megalocephala | USDA symbol: LAME3

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.
