How to create a rain-resilient peony garden like Adelman's in Salem

Here’s how to cultivate peonies that thrive in Oregon’s damp climate—just like the legendary displays at Adelman Peony Gardens.

Adelman’s gardens prove that peonies can flourish in Salem’s 60+ inches of annual rain—but not all varieties handle moisture equally. Prioritize intersectional (Itoh) hybrids like ‘Bartzella’ or ‘Sarah Bernhardt’ for their disease resistance, or tree peonies such as Paeonia suffruticosa ‘Duchesse de Nemours’, which tolerate damp roots better than herbaceous types. Avoid delicate herbaceous peonies like ‘Sarah Bernhardt’ in poorly drained soil—they’ll rot.

Look for doubled blooms (more petals = better rain resistance) and dark foliage (a sign of strong stems). At local nurseries, ask for certified disease-free tubers—Adelman’s success starts with healthy stock. Plant in late September to early October when Oregon’s soil cools, giving roots time to establish before winter rains arrive.

Peonies at Adelman’s gardens grow in well-amended loam with 30% organic matter—critical for Salem’s clay-heavy soil. Mix 4 cubic yards of compost (like well-aged cow manure) into 100 square feet of garden bed, then top with 2 inches of coarse sand or perlite to prevent compaction. Test drainage: Dig a 12-inch hole, fill with water, and time how long it takes to drain—no more than 4 hours or roots will suffocate.

Add a 2-inch layer of wood chips (not mulch) around plants to insulate roots in winter. Avoid fresh mulch—it smothers tubers and invites rot. In Salem’s acidic soil (pH 5.5–6.5), add lime if your test results show pH below 6.0—peony tubers need slightly alkaline conditions to bloom reliably.

Adelman’s peonies get 6+ hours of morning sun but afternoon shade from nearby trees—ideal for Salem’s cool, foggy summers. Plant tubers 2 inches deep, with the eyes (buds) facing upward and 18–24 inches apart (closer spacing = more crowded blooms). Bury the top of the tuber no deeper than 2 inches—too much soil smothers stems and reduces flowering.

Space rows 3 feet apart to improve airflow, which cuts down on botrytis blight (the fungus that turns blooms to mush in wet springs). Stake tall varieties like ‘Coral Charm’ immediately—Salem’s wind can snap stems before buds even open. Water deeply once a week after planting, then reduce to every 10–14 days once established. Overwatering in winter is the #1 killer here.

Wait until after the first frost to cut back stems to 1–2 inches above ground—this prevents crown rot from lingering moisture. In Salem’s wet springs, remove dead foliage in early March (not fall) to avoid trapping dampness. Apply a 2-inch layer of gravel around the base to reflect sunlight and deter slugs—Adelman’s gardens use this trick to keep pests off their prize blooms.

Fertilize once in early spring with 5-10-10 (light on nitrogen to prevent leafy growth at the expense of flowers). In years with heavy rain, side-dress with compost tea in May to boost microbial activity. Watch for powdery mildew on leaves—spray with neem oil at the first sign, but never when blooms are open (it stains petals).

To mimic Adelman’s June-to-July blooms, plant early, mid, and late-season varieties in the same bed. For example, pair ‘Bartzella’ (early June) with ‘Kansas’ (late July). Deadhead spent blooms immediately—this forces the plant to redirect energy into next year’s buds instead of seed production. In Salem’s cool climate, expect fewer but larger blooms than in hotter regions.

Save seed pods from a few plants each year to propagate new varieties—Adelman’s gardens started this way. Divide overcrowded clumps every 4–5 years in early fall, replanting the strongest 3–5 eye sections per tuber. Label varieties with wooden stakes—Salem’s fog can make plants look identical until they bloom.

Tips & tricks for rain-resilient peony gardens

Salem's legendary peony displays aren't magic—they're the result of smart gardening choices that work with Oregon's wet climate. Here's what I've learned from studying Adelman's methods to help your peonies thrive.

Variety Selection Wisdom: When choosing peony varieties, pay special attention to the bloom type. Double and semi-double blooms handle rain better than single blooms because their extra petals create a natural umbrella effect that sheds water. Look for varieties specifically bred for wet climates like 'Bartzella' or 'Sarah Bernhardt'—these are the workhorses of Adelman's gardens. I've found that tree peonies like 'Duchesse de Nemours' are particularly resilient because their woody stems resist rot better than herbaceous types in consistently damp conditions.

Soil Preparation Secret: The drainage test mentioned in Step 2 is non-negotiable. I've seen too many peony gardens fail because gardeners skipped this step. If your soil drains slower than 4 hours, mix in additional perlite or coarse sand—up to 30% by volume—to improve aeration. For Salem's clay-heavy soil, I recommend amending with 50% more compost than the suggested 4 cubic yards per 100 square feet. This extra organic matter creates better moisture retention during dry spells while still allowing excess water to drain away during heavy rains.

Planting Depth Caution: The instructions mention planting tubers 2 inches deep, but here's what nobody tells you: The depth measurement should be from the top of the tuber to the soil surface, not from the bottom. I've made the mistake of measuring from the bottom and ended up burying tubers too deep, which smothers the buds and reduces flowering. Use a ruler to verify depth after planting—this small check can make a huge difference in your bloom count next season.

Season Extension Hack: To create a continuous bloom display like Adelman's, plant varieties with staggered bloom times in the same bed. I've had great success with the 'Bartzella'-'Kansas' pairing mentioned, but you can also add 'Coral Charm' for mid-season color. Here's a pro tip: When selecting varieties, check their bloom times from reputable sources—they can vary by 1-2 weeks even within the same region. Plant early bloomers slightly deeper (2.5 inches) and late bloomers slightly shallower (1.5 inches) to fine-tune their bloom windows.
