Marmalade
Echinacea 'Marmalade'
Marmalade blooms from July through September.
Months here are Northern Hemisphere months; in the Southern Hemisphere, shift them by six months.
Growing Marmalade
Plant it in full sun. It prefers low water. It is hardy in USDA zones 4–9. Expect it to reach about 2.5 ft tall and 1.5 ft wide at maturity, in roughly 2 years (not yet checked).
No toxicity note is on file for Marmalade. That is not a clearance: check its safety for people and pets before planting.
What was checked
Mature height and spread, hardiness zones, sun and the trait tags were checked against named botanical sources for this plant. The bloom months and water need on this page were not, and each fact above says which. 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 Marmalade
Plant Marmalade 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 6, the middle of its hardy zones 4 to 9, spring means March to May and fall means August or September. Once settled, it blooms from July to September.
Month-by-month timing for your zone is on the planting calendar; if you garden near zone 6, the middle of this plant's hardy range, start with zone 6 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 Marmalade
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Marmalade about 1.5 ft apart, center to center, so each plant has room to reach its full width.
Add Marmalade 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
Marmalade's height, spread, hardiness zones, sun and trait tags were checked against 8 published sources on July 30, 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.
