Gumpo Pink
Rhododendron 'Gumpo Pink'
Gumpo Pink blooms from May through June.
Months here are Northern Hemisphere months; in the Southern Hemisphere, shift them by six months.
Growing Gumpo Pink
Plant it in part shade. It prefers moderate water. It is hardy in USDA zones 6–9. Expect it to reach about 1.5 ft tall and 2.5 ft wide at maturity, in roughly 4 years (a house reading).
What was checked
Fifteen fields were checked against named botanical sources, each recorded beside the sources that carried it, with every unsettled point written down and decided: mature height and spread, hardiness zones, sun, water, bloom months and color, the trait tags, soil, diseases, pests, toxicity, the plant's own names, and years to mature size, which rests on a recorded house rule where no publisher states one and is marked so. 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 Gumpo Pink
Plant Gumpo Pink 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 7, the middle of its hardy zones 6 to 9, spring means March to May and fall means September or October. Once settled, it blooms from May to June.
Month-by-month timing for your zone is on the planting calendar; if you garden near zone 7, the middle of this plant's hardy range, start with zone 7 in March. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

How far apart to plant Gumpo Pink
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Gumpo Pink about 2.5 ft apart, center to center, so each plant has room to reach its full width.
Add Gumpo Pink 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
Gumpo Pink's height, spread, hardiness zones, sun, water, bloom months and color, trait tags, soil, diseases, pests and toxicity were checked against 15 published sources on August 24, 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.
