If you live in Whisper Mountain, this is the only plant list you need.

Whisper Mountain enforces a specific approved plant palette — getting it wrong means rework, fines, or a rejected ACC application. We pulled the official guidelines, extracted every plant, and matched it against our nursery catalog. 78 of Whisper Mountain's approved species are carried by Three Timbers — organized below by the same categories the ACC uses.

Every plant below is clickable. Click any plant to see sizes, current pricing, and our 30-day plant warranty terms. Free delivery to Mesa on orders over $150.

Planting & Watering Guide for the Phoenix Valley

Best time to plant

• Trees & shrubs: October through March. Avoid June, July, August.
• Cacti, agaves & ocotillo: April through October. They need warm soil to root in.
• Groundcovers & perennials: Spring (Feb–April) or fall (Sep–Nov).

Watering schedule

• Year 1, summer (June–September): Every 3–4 days, deep soak (run drip for 90 minutes per zone).
• Year 1, winter (Nov–Feb): Every 10–14 days, light watering.
• After year 1, established: Every 10–14 days in summer, every 3–4 weeks in winter. Cacti, agaves, and ocotillo need far less.

Frequently Asked Questions

Are all these plants approved at every Whisper Mountain property?

These are the species permitted under Whisper Mountain's current landscape guidelines. Some sub-villages or front-yard-vs-backyard restrictions may apply — always check your specific lot's design package or submit an ACC application before installing.

Does Three Timbers handle the ACC submittal?

Yes — if you use our professional install service, we handle the ACC paperwork, plant list, and submittal for you. Just provide your homeowner contact info and we'll do the rest.
