What was checked
Mature height and spread, hardiness zones, sun, water, bloom months and color and the trait tags were checked against named botanical sources for this plant, with what the sources could not settle written down; years to mature size rests on a recorded house rule where no publisher states one, and is marked so; its common name and alternate names have not been checked yet. 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 Coral Fountain
Wait until all danger of frost has passed, then plant out Coral Fountain into warm soil; in most zones that means late spring. Planted then, it flowers from July to October.
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 February. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

How far apart to plant Coral Fountain
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Coral Fountain about 1.5 ft apart, center to center, so each plant has room to reach its full width.
Add Coral Fountain 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
Coral Fountain's height, spread, hardiness zones, sun, water, bloom months and color, years to mature size, trait tags, soil, diseases, pests and toxicity were checked against 10 published sources on August 23, 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.
