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 Ivy Geranium
Wait until all danger of frost has passed, then plant out Ivy Geranium into warm soil; in most zones that means late spring. Planted then, it flowers from May to October.
Month-by-month timing for your zone is on the planting calendar. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

How far apart to plant Ivy Geranium
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Ivy Geranium about 20 in apart, center to center, so each plant has room to reach its full width.
Add Ivy Geranium 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
Ivy Geranium's height, spread, hardiness zones, sun, water, bloom months and color and trait tags were checked against 4 published sources on October 27, 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.
