Pets

  • Not yet checked for pets.

Lists differ and none is complete. If a pet eats a plant and seems unwell, call a veterinarian or a pet poison helpline.

No toxicity note is on file for Catalina Cherry. That is not a clearance: check its safety for people and pets before planting.

Verification
What was checked

Nine facts were checked against named botanical sources, each recorded beside the sources that carried it: mature height and spread, hardiness zones, sun, water, bloom months and color, the trait tags, and years to mature size, which rests on a recorded house rule where no publisher states one and is marked so. Soil, diseases, pests, toxicity and the plant's own names have not yet been read for this plant, and its trait tags are the ones a feature uses rather than every word a page prints. Each fact above carries its own mark. The planting, spacing and size sections are derived from these checked facts by a fixed rule, not checked separately, and the plant type is the library's own classification.

When to plant Catalina Cherry

Plant Catalina Cherry in early spring as soon as the soil is workable, or in early fall at least six weeks before your first frost, so roots establish in cool weather. In zone 9, the middle of its hardy zones 9 to 10, spring means January to March and fall means October or November. Once settled, it blooms from April to May.

Month-by-month timing for your zone is on the planting calendar; if you garden near zone 9, the middle of this plant's hardy range, start with zone 9 in January. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

How big does Catalina Cherry get?

See Catalina Cherry in a garden plan: the planner shows it in 3D beside everything else you add, growing toward this size over the years.

How far apart to plant Catalina Cherry

Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.

Give Catalina Cherry about 16 ft of clear ground in every direction, measured from its center. It is one plant with room around it, not a row, and a raised bed is too small for it.

Where these facts come from

Catalina Cherry's height, spread, hardiness zones, sun, water, bloom months and color and trait tags were checked against 5 published sources on November 5, 2026. Each one is linked below with every fact it carried, which can include a fact this page still marks as not yet checked, because a source carrying a value is not the same as the value being held to the standard. Facts not in that list, and the planting, spacing and size sections, are not covered by these sources.
