Mystery Astilbe Relative: Astilboides tabularis (Shieldleaf)

You and your mom (Zone 4/5 NY) sell perennials and have a plant labeled "Astilbicide Tubularis" — likely Astilboides tabularis (Shieldleaf, formerly Astilbe tabularis). Not a true astilbe, but a stunning foliage perennial.

What It Is

• Huge, round, parasol-like leaves (2–3 ft across).
• White astilbe-like plumes in early summer (3–4 ft).
• Slow-spreading rhizomes. Long-lived.
• Native to Manchuria/Korea. Zone 3–7 hardy.
• Swedish nurseries sell it as "Parasollblad" (parasol leaf).

Culture

• Moist, rich, woodland soil. Part to full shade.
• Consistent moisture critical — no drought.
• Morning sun OK if soil stays wet.

Division = Easy Propagation

1. Early fall or early spring.
2. Dig clump; cut rhizomes into sections with 1+ bud + roots.
3. Replant with bone meal (no nitrogen).
4. Water well; mulch after frost.

Why It's Not in USDA Databases

Uncommon in US trade. More popular in Scandinavia/UK. But perfectly hardy for you.
