You'd probably get better info from the medit-plants list, but here's what I
know...

--Here in Zone 9, the ones I have tried are very easy to grow. I can't
speak to hardiness in your area.

--They like lots of sun, which may be an issue in your area.

--Mine are slow-growing on my hill, which is south-facing, nutrient-poor
clay subsoil. The good news is that I've had no problems with root rot.

--They appreciate some summer water here, but I bet they would not need
supplemental water where you are.

--The clumps get crowded over time. I probably need to divide mine.

--The flowers are worth the (minimal) effort.
