Symphyotrichum novae-angliae 'Alma Pötschke'
Alma Pötschke blooms from September through October.
Months here are Northern Hemisphere months; in the Southern Hemisphere, shift them by six months.
Growing Alma Pötschke
Plant it in full sun. It prefers moderate water. It is hardy in USDA zones 4–8. Expect it to reach about 3 ft tall and 2 ft wide at maturity, in roughly 2 years (checked).
No toxicity note is on file for Alma Pötschke. That is not a clearance: check its safety for people and pets before planting.
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 Alma Pötschke
Plant Alma Pötschke 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 8, spring means March to May and fall means August or September. Once settled, it blooms from September to October.
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 Alma Pötschke
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Alma Pötschke about 2 ft apart, center to center, so each plant has room to reach its full width.
Add Alma Pötschke 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
Alma Pötschke'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 11 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.
