What a name for a really beautiful groundcover. Veronica pectinata only grows about two inches high, tolerates doughty soils, stays green long into the fall, and is hardy to zone 3. Here’s the real treasure of the plant:
Veronica pectinata in spring
The plants cover themselves with these beautiful true-blue flowers that last a week or so. They look beautiful under crocus, tulips and daffodils.
Looking up information about this veronica, I learned it is a source for ehrenoside, a phenylpropanoid glycoside.

Here’s a bit of gleaned information from Wikipedia about phenylpropanoids: Phenylpropanoids are a class of plant-derived organic compounds that are biosynthesized from the amino acid phenylalanine. They have a wide variety of functions, including defense against herbivores, microbial attack, or other sources of injury; as structural components of cell walls; as protection from ultraviolet light; as pigments; and as signaling molecules.

So who knows? Veronica pectinata might become one of those herbs important beyond their garden functions and beauty!
