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 Smooth Rose. That is not a clearance: check its safety for people and pets before planting.
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 Smooth Rose
Plant Smooth Rose 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 4, the middle of its hardy zones 3 to 6, spring means April to June and fall means July or August. Once settled, it blooms from June to July.
Month-by-month timing for your zone is on the planting calendar; if you garden near zone 4, the middle of this plant's hardy range, start with zone 4 in April. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

How far apart to plant Smooth Rose
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Smooth Rose about 5 ft apart, center to center, so each plant has room to reach its full width.
Add Smooth Rose to a garden plan and the planner draws it at its full width, so you see the spacing before you buy.
Where these facts come from
Smooth Rose's height, spread, hardiness zones, sun, water, bloom months and color and trait tags were checked against 8 published sources on October 25, 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.
