Hardiness guidance

USDA zones 5–9; especially dependable in cooler Valley and high-desert gardens

Before you plant

These conditions determine whether it will thrive.

Cold hardiness

Hardy here

Very cold hardy. It just goes dormant below about 10°F, which never happens in Phoenix.

Leaves and wood: damaged below 10°F

Heat tolerance

Shade from late-afternoon sun

Full sun is fine in winter and spring, but it struggles above about 105°F. In Phoenix give it afternoon shade and keep it away from reflected heat off walls, drives and sidewalks.

Right plant, right place

Will Angelita daisy grow at your Arizona property?

Best at path edges, between rocks, and in small masses where its fine scale remains visible.

Best regional fit: Valley suburbs · USDA 9a–9b, Desert outskirts · USDA 8b–9b, High desert · USDA 6a–8b.

Light

Sun exposure

Full sun; afternoon relief can prolong bloom in the hottest low-desert sites.

Water

Irrigation

Low. Deep watering every 10–14 days during hot weather can maintain flowering; avoid a wet crown.

Cultivars & selections

Usually sold as the species rather than named cultivars. Choose compact, densely crowned plants and local or regional nursery stock.

Plants vary slightly in leaf width and flower timing. Good crown density and healthy roots are more useful selection criteria than a cultivar label.

Planting & stewardship

How to help Angelita daisy thrive

1
Confirm the plant’s mature spread and underground conflicts before digging.
2
Place the root flare at finished grade and keep mulch away from the trunk.
3
Establish a wide, deep root zone instead of irrigating only at the trunk.
4
Observe seasonal growth, heat stress, and wildlife use before making major pruning changes.
