Verbena tapien/blue annual or perennial?

datura222October 6, 2012

I am wondering if blue/violet verbena tapien is actually a reliable perennial in San Jose (sunset zone 15 i think?, or zone 9) or should be thought of as an annual to be discarded after a season?

I am looking for a low growing groundcover and really like the way it looks.

Thanks for any input :)

Hardiness is supposed to be from 8a - 11b. I'm in zone 10 I think, and mine keeps growing all year.

In my opinion it isn't dependable as a long lived perennial ground cover here in northern California, especially if you want good appearance year round. I haven't grown it in areas with warmer summers, in Sunset zones 16/17 it generally lasted less than a year; some individual plants would live over, up to 50% would croak.

Thank for the replies I really appreciate the input :)

I bought some myoporum parvifolium 'pink' just in case the verbena doesn't pull through. It looks low growing, dense and seems to be evergreen. Do either of you know how much each plant will actually spred? I read on the tag 24", but on some websites I am seeing 5 feet....not sure what I should space these at.
I just wanted some negative space...so I need a plant that would make a nice spreading groundcover for the eyes to rest on when surrounded by other plants.

The Myoporum parvifolium 'Dwarf Pink form' is a great very low spreading ground cover, I use it a lot. I usually plant it at about a 12 to 18 inch spacing from flats or cell packs, as it is pretty fast growing, and after 2 or more years, yes, it can spread up to 4 feet across. Closer spacing isn't really a problem, but avoid planting it too close to edges of pavement or you'll need to trim it quite often. If you are planting it from one gallon cans, I'd space it more like 2 to 3 feet on center. Dymondia margaratae is another great low ground cover, and Dwarf Mondo Grass works well as well.
