USDA Plant Hardiness Zone Map

Close

Roldana petasitis, or Velvet Groundsel, is a small shrub native to Mexico that typically grows between 2 and 5 feet tall. It has large round leaves tinged in purple and are hairy to the touch. When in bloom, the shrub produces bunches of yellow and orange daisy looking flowers. The flowers will then produce seeds in profusion which will be wind borne and can make it invasive if not properly managed.

When caring for Roldana petasitis, it needs to be situated in full sun or semi-shade and receive regular water. It is recommended to prune it hard after it blooms to maintain its shape and size. It is grown in USDA Zone 9-11 and can survive in cold regions when planted in a pot. If grown in a pot, it should be positioned in full sun and watered regularly as to not let the soil dry out. It should also be fertilized on a monthly basis to ensure healthy growth.
