Deutschland
Astilbe japonica 'Deutschland'
Deutschland blooms from June through July.
Months here are Northern Hemisphere months; in the Southern Hemisphere, shift them by six months.
Growing Deutschland
Plant it in part shade. It prefers high water. It is hardy in USDA zones 4–9. Expect it to reach about 20 in tall and 16 in wide at maturity, in roughly 2 years (a house reading).
No toxicity note is on file for Deutschland. That is not a clearance: check its safety for people and pets before planting.
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 Deutschland
Plant Deutschland 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 June to July.
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 Deutschland
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Deutschland about 16 in apart, center to center, so each plant has room to reach its full width.
Add Deutschland 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
Deutschland's height, spread, hardiness zones, sun, water, bloom months and color, trait tags, soil, diseases, pests and toxicity were checked against 20 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.
