Some of your plants are not as drought tolerant as others so placement of those and the ability to water as necessary is critical. In particular, the echinacea (coneflowers), penstemon and the May Night salvia are thirstier than the others. Also the kangaroo paws vary in their water needs - some species/cultivars are more DT than others.

The BeWaterWise or California Friendly Gardening programs are great resources for you. I've linked to one resource for Orange County that may be helpful. Be sure to take some time to go through the photo gallery........there are some stunning xeric gardens included that you can use for inspiration as well as to gather some tips for placement.

While you don't necessarily need to be restricted to natives, they are a great source of plant material to select from, being both ideally suited to climate as well as having low water needs. And they are generally colorful, attractive to wildlife and not much bothered by pests or disease issues.

Any lavender will work and they are pretty commonly found in most nurseries - both English and Spanish lavender are great xeric plants and put on a long lasting flower show but I wouldn't spend a lot of lime looking for so-called "colored" varieties (lemon lavender very blah in flower - hardly noticeable).

Other plants I would consider including are California fuchsia (Zauschneria californica, aka Epilobium canum), manzanita (Arctostaphylos species), California lilac (Ceanothus), Salvia greggii, S. jamensis and Justicia californica.

byw, Rogers Gardens in Corona del Mar is an excellent resource for this type of project. You might also get some very good feedback on your plans in the Californium Gardening forum.

Awesome - yes after not getting much responses here i moved the discussion over to the garden forum. But really do want to thank you for the advice with respect to the differing watering requirements - after reviewing the plants you mentioned Think i might take you up on your suggestion to axe a few of the plants listed and perhaps even suggest the creeping mountain lilac to be used a spotty groundcover to add interest. I also like your suggestion of the California fuchsia. I will update the other post to reflect this [here is a link to it [(https://www.houzz.com/discussions/xeriscape-front-lawn-design-seek-guidance-ca-orange-county-dsvw-vd~3482997).

But again want to thank you as as i find your suggestions very helpful as im having a hard time finding people here in the area that specialize in desert/xeriscape landscaping.

"im having a hard time finding people here in the area that specialize in desert/xeriscape landscaping."

I find that difficult to believe...........in the middle of a major, long lasting drought, SoCal homeowners (as well as in many other areas of CA) are frantically replacing 'traditional', water sucking landscapes with drought tolerant xeric ones. And getting rebates to do so!

The California Gardening forum here on GardenWeb has had numerous threads discussing this very subject, which is why I suggested you post there to get input from folks who have already gone through this traditional-to-xeric conversion. FWIW, if you want or need ANY info about plants, gardening or landscaping, the GardenWeb forums are the best place to find it, not on the regular Houzz design forums. They don't know poop about plants :-)

The jasmine doesn't seem to go with your other choices. For planting success, you should plant in hydrozones, grouping plants with similar water needs. The garden section of Bewaterwise has many examples of home landscapes that should give you ideas, as does the link below from Irvine Ranch Water District. You can also visit the Fullerton Arboretum and Coastkeepers garden in Orange.
