Origins & Description

The American arborvitae (Thuja occidentalis) is native to North America, thriving naturally in the upper Midwest and Northeast. Over time, plant breeders have developed cultivars to suit modern landscapes. North Pole® is a Proven Winners® selection prized for its dense, upright growth and cold hardiness.

The foliage is lush, dark green, and retains its color throughout winter, even in Wisconsin’s cold, snowy conditions where some evergreens may bronze. Its natural columnar form means it typically needs little to no pruning to stay neat and narrow. This makes it a fantastic option for low-maintenance hedges, natural fences, or focal-point plantings.

Ideal Growing Conditions (Southeast Wisconsin Focus)

• Light: Full sun to part sun. Grows best with at least 6 hours of direct sun daily.

• Soil: Prefers moist, well-drained soils, but tolerates clay and sandy conditions with adequate care.

• Moisture: Consistent moisture is important, especially in the first 1–2 years. Once established, it is moderately drought tolerant.

• pH: Neutral to slightly alkaline soils are ideal.

• Hardiness: Extremely cold-hardy, thriving in Zone 3 winters. Perfectly suited to Wisconsin’s climate.

Planting & Establishment

When to Plant:

• Spring (April–May): Gives roots the longest time to settle before winter.

• Early Fall (September): Also effective, as roots will continue to grow while the soil is warm.

How to Plant:

1. Dig a hole twice as wide as the root ball and equal in depth.

2. Place the plant so the crown is level with the soil surface.

3. Backfill with native soil, firm gently, and water thoroughly.

4. Apply a 2–3 inch mulch ring around the base to conserve moisture, keeping mulch a few inches away from the trunk.

Spacing: For privacy screens, plant 3–5 feet apart. For stand-alone specimens, allow full width (about 5 feet) to let the natural shape shine.

Care & Maintenance

• Watering: Water deeply and regularly during the first two years. Established plants can handle some drought, but occasional deep watering keeps them healthiest.

• Fertilizer: Apply a balanced, slow-release fertilizer in spring for optimal growth. Avoid excessive nitrogen.

• Pruning: Minimal. Naturally narrow, but can be lightly trimmed in late spring if needed. Avoid heavy pruning into old wood.

• Winter Care: In windy or exposed sites, burlap wraps can prevent winter burn in the first few years. Avoid piling snow directly against plants.

• Longevity: With proper care, North Pole® can thrive for decades as a structural anchor in the landscape.

Landscape Uses & Companions

• Privacy Screens: Narrow footprint makes it excellent for hedges along property lines.

• Windbreaks: Plant in rows to reduce wind around patios or gardens.

• Focal Points: Use as vertical accents in mixed borders or near entryways.

Grape Lollipop Phlox (Phlox paniculata ‘Ditomsur’ PP21,109)

Common Name: Grape Lollipop Garden Phlox
Bloom Time: Mid-summer through early fall (July–September)
USDA Zones: 3–8 (reliably hardy in Southeast Wisconsin)
Mature Size: 18–24 in. tall × 18–24 in. wide
Habit: Compact, upright clump with rounded flower heads
Fragrance: Sweet, classic phlox scent

Introduction

Just when many perennials are starting to slow down, Grape Lollipop Phlox shifts into high gear with dome-shaped clusters of saturated, grape-purple flowers. Its compact habit, excellent color retention, and improved disease performance make it a go-to choice for late summer color in Southeast Wisconsin. Whether you’re refreshing a cottage border, brightening a pollinator bed, or planting a mixed container for the patio, this cultivar brings reliable, high-impact bloom with far less fuss than older phlox varieties.

Looking to plant this season? Heritage Hill Nursery carries Phlox paniculata ‘Grape Lollipop’—see it here:
https://heritagehillnurseryinc.com/product/phlox-paniculata-grape-lollipop/

Origins & Description

Phlox paniculata is the classic “garden phlox,” valued for tall stems topped with fragrant flower panicles that attract butterflies, bees, and hummingbirds. The ‘Grape Lollipop’ selection (botanical name ‘Ditomsur’) refines that formula: it stays neatly compact (generally under two feet), holds rounded, lollipop-like flower heads, and colors up in a deep grape-purple that reads vividly from a distance. Individual florets are five-petaled and can show a faintly lighter halo or small eye toward the center, adding dimension. Sturdy, medium-green foliage forms a dense mound that helps the plant look tidy even between bloom flushes.

Another advantage of this cultivar is its improved garden performance relative to older tall phlox—especially in regard to foliar diseases when given proper spacing and air flow. For home gardeners, that translates to a plant that maintains attractive leaves while pumping out blooms for weeks.

Ideal Growing Conditions (Southeast Wisconsin Focus)

• Light: Full sun (6+ hours) yields the strongest stems, tightest habit, and most abundant flowers. In very hot exposures, a touch of afternoon shade is fine and can extend bloom.

• Soil: Best in moist, well-drained, fertile soils. Work in 2–3 inches of compost before planting to boost structure and water-holding capacity, particularly in sandy or heavy clay sites common in our region.

• pH: Slightly acidic to neutral (approx. 6.0–7.0) is ideal, but this phlox is adaptable if drainage and fertility are good.

• Water: Keep evenly moist during active growth; aim for about 1 inch of water per week from rain or irrigation. Consistency helps maximize flower size and longevity.

• Airflow: Good air circulation is essential. Space plants 18–24 inches apart and avoid crowding with bulky neighbors; this dramatically reduces mildew pressure.

• Hardiness: Winter hardy across Southeastern Wisconsin. A light mulch after the ground freezes (late fall) helps moderate freeze-thaw cycles.

Planting & Establishment

Timing: Plant in spring after the last hard frost or in early fall (late August–September) so roots can establish while the soil is warm. Early fall planting is particularly effective here; roots keep growing into October even as tops slow down.

How to Plant:

1. Dig a hole twice as wide as the root ball and as deep as the pot.

2. Set the crown level with the surrounding soil—don’t bury the stems.

3. Backfill with native soil amended with compost, firm gently, and water thoroughly.

4. Top with 2–3 inches of organic mulch, keeping mulch 1 inch off the stems.

Aftercare, Year 1: Water deeply whenever the top couple inches of soil dry out. Consistent moisture in the first season sets the stage for a fuller plant and heavier bloom the following summer.

Care & Maintenance

• Watering: Once established, water during dry spells to maintain steady growth and prevent stress-related leaf issues. Morning watering at the soil line (soaker hose or drip) is ideal.

• Feeding: In early spring, scratch in a balanced, slow-release fertilizer or a thin layer of compost. Avoid high-nitrogen spikes midseason, which can push soft foliage at the expense of flowers.

• Deadheading: Clip away spent flower heads to encourage a lighter rebloom and keep the plant looking tidy.

• Cutback: In late fall after a hard frost or in early spring, cut stems back to 2–4 inches. Removing old stems improves airflow around the new shoots.

• Division: Every 3–4 years, divide clumps in early spring to maintain vigor and produce additional plants. Replant divisions at original depth and water well.

• Pests & Disease: Modern selections like ‘Grape Lollipop’ hold foliage well when spaced correctly. Still, practice good hygiene—clean up fallen leaves in autumn and water at soil level. If deer or rabbits are active in your area, consider a repellent during tender spring growth.

Design Ideas & Companions

• Front-to-Mid Border Color: The smaller size of ‘Grape Lollipop’ fits perfectly at the front or mid border where traditional tall phlox might loom.

• Pollinator Beds: Its nectar-rich blooms are excellent for butterflies, bees, and hummingbirds. Place near Echinacea, Monarda, Agastache, or Rudbeckia to build a succession of summer-to-fall food sources.

• Texture Pairings: Contrast the rounded flower heads against fine grasses like Panicum ‘Northwind’ or Schizachyrium scoparium; the airy blades frame the bold color and extend interest into autumn.

• Containers: In a 16–20″ patio pot, combine ‘Grape Lollipop’ with a mounded silver foliage plant (like Artemisia or Helichrysum) and a trailing accent (such as Calibrachoa) for long-season impact.

• Color Palettes:

  • Monochrome: Pair with salvias and purple coneflowers for a cool violet scheme.

  • Complementary: Add golden yellows (e.g., Coreopsis, Helenium) for high-contrast pop in late summer.

  • Soft Pastels: Soften with pale pinks and whites (e.g., Phlox ‘David’, Shasta daisy) to create an evening-friendly border.

Seasonal Calendar (Southeast Wisconsin)

• March–April: Clean up old stems; top-dress with compost; apply slow-release fertilizer.

• May–June: Monitor moisture as growth accelerates; ensure spacing remains open around the plant.

• July–September: Peak bloom. Deadhead spent clusters to neaten and extend the show.

• October: Continue watering until the ground starts to freeze if rainfall is scarce—roots still grow in warm soil.

• Late Fall: After a killing frost, cut back and mulch lightly once the ground has cooled.

Troubleshooting Tips

• Powdery Mildew: Most often a spacing/airflow issue. Widen spacing, thin nearby plant bulk, water at soil level, and avoid overhead irrigation late in the day.

• Flop/Lean: Rare with this compact cultivar. If it occurs after storms, a low, unobtrusive hoop support added early in the season can help.

• Sparse Bloom: Typically from insufficient sun or over-rich nitrogen. Move to a brighter spot and use balanced feeding next spring.

• Short Bloom Window: Deadhead promptly, maintain even moisture, and avoid severe drought stress to keep flowers coming.

Ecological & Garden Value

‘Grape Lollipop’ is a pollinator powerhouse at a time of year when fresh nectar is essential. Its continuous, fragrant bloom supports a range of beneficial insects, while the compact habit allows gardeners with smaller spaces to contribute meaningfully to backyard biodiversity. Because this cultivar holds foliage well, it also provides a more attractive, low-maintenance presence in ornamental beds through late season.

Ironweed

Common Name: Prairie Ironweed
Bloom Time: Late summer (August–September)
USDA Zones: 3–9
Mature Size: 4–6 ft tall × 2–3 ft wide

Introduction

As summer wanes and many garden perennials begin to fade, Prairie Ironweed emerges in glorious purples, casting tall, wispy plumes of nectar-rich flowerheads atop sturdy stems. A true native of Midwestern prairies, Vernonia fasciculata brings vertical interest, wildlife value, and late-season drama to South East Wisconsin landscapes. In this spotlight, we’ll delve into its natural history, cultural needs, care guidelines, and inspiring landscape uses—everything you need to showcase Ironweed at Heritage Hill Nursery from August 22 through August 31.

Origins and Description

Native to prairies, meadows, and streambanks of the central and eastern United States, Prairie Ironweed has long been prized for its hardiness and bold form. Unlike its cousin, Vernonia noveboracensis, which often nods its heads, V. fasciculata maintains an upright, saxophone-like posture. Narrow, lance-shaped leaves cluster along stiff, reddish stems. In late summer, terminal clusters of tiny, tubular florets—each only ⅓″ across—collectively form airy corymbs measuring 3–5″ across. The intense magenta-purple hue unfolds in waves, attracting bees, butterflies (notably Monarchs and Swallowtails), and even hummingbirds.

Ideal Growing Conditions

• Light: Full sun (at least 6–8 hours daily) ensures robust flowering and strong stem development.

• Soil: Adaptable to a variety of soils—from sandy loams to heavier clays—as long as it’s well-drained. Ironweed tolerates occasional wet feet, making it suitable for rain gardens and bioswales.

• pH: Prefers neutral to slightly acidic soils (pH 6.0–7.0).

• Moisture: Consistent moisture throughout the growing season promotes larger blooms; however, established plants withstand short droughts.

• Hardiness: Withstands Wisconsin’s winter lows (down to –40°F in Zone 3) once established. A late-fall mulch helps protect crowns from freeze–thaw cycles.

Planting and Establishment

1. Timing: Plant in spring after danger of frost has passed (mid-April–May) or in early fall (late September–early October).

2. Site Preparation: Clear the area of weeds and grass competition. Amend heavy soils with compost (up to 25% by volume) to improve structure.

3. Planting: Dig a hole twice as wide as the root ball and of equal depth. Position the crown level with surrounding soil. Backfill gently, firming soil to eliminate air pockets.

4. Mulching & Watering: Apply a 2″–3″ layer of organic mulch, keeping it an inch from the stem base. Water deeply at planting, then about 1″ per week until established (two growing seasons).

Care and Maintenance

• Watering: Use drip irrigation or soaker hoses to maintain even soil moisture in summer. Reduce watering once plants mature.

• Fertilization: Ironweed rarely needs fertilization if planted in average soils. If growth is slow, a light spring application of a balanced, slow-release fertilizer encourages vigor.

• Staking: In windy sites or if crowded, consider discreetly staking stems to prevent lodging.

• Pest & Disease: Generally pest-free. Good spacing (2–3′ apart) and air circulation reduce the risk of powdery mildew.

Pruning and Propagation

• Pruning: Cut back spent flower stalks after bloom to tidy the garden and potentially encourage a light rebloom. In late fall or early spring, cut stems to 6″ above ground to encourage fresh growth.

• Division: Every 3–4 years, divide large clumps in early spring. This refreshes vigor and provides additional plants for the landscape.

• Seed: Ironweed self-seeds readily—collect seeds in autumn for sowing in flats or direct sow in prepared beds. Stratification for 60–90 days improves germination.

Landscape Uses and Companions

Whether you’re planting a compact border or seeking a reliable garden performer, FlowerFull® brings a blend of form, function, and hardiness that’s ideal for South East Wisconsin landscapes.

Origins and Description

Hydrangea arborescens—commonly called smooth hydrangea—is native to the woodlands of the eastern United States. Traditional varieties like ‘Annabelle’ set the stage, but FlowerFull® takes performance to the next level. Bred by Bailey Nurseries (PP35,613), FlowerFull® was selected for its exceptional bloom count, disease-resistant foliage, and superior stem strength. Each dome-shaped flowerhead measures up to 8″ across, composed of hundreds of four-petaled florets that emerge crisp white and gradually age to a creamy green. The foliage stays clean and glossy throughout the season, providing a lush backdrop to the stunning blooms.

Ideal Growing Conditions

• Light: FlowerFull® thrives in full sun to partial shade. In South East Wisconsin, provide at least four hours of morning sun, with afternoon shade helping preserve bloom quality on the hottest days.

• Soil: Prefers rich, well-drained soil with good moisture retention. Amend heavy clay with compost to improve aeration, or add organic matter to sandy soils to boost water-holding capacity.

• Moisture: Consistent moisture is key, especially during bloom development. Once established, FlowerFull® tolerates brief dry spells, but regular irrigation will maximize flower size and longevity.

• Hardiness: Rated for USDA Zones 3–8, this smooth hydrangea stands up to -30°F winter lows. A light layer of mulch in late fall helps protect roots and moderates soil temperature.

Planting and Establishment

1. Timing: Plant in spring after soil warms (mid-April to early May) or in fall (late September) at least six weeks before the first frost.

2. Site Preparation: Clear weeds and grass within the planting area. Dig a hole twice the width of the root ball and as deep as its height, working compost into the backfill soil (up to 25% by volume).

3. Planting: Set the root crown level with the surrounding soil. Backfill gently, firming soil to eliminate air pockets, then water thoroughly.

4. Mulching: Apply a 2–3″ layer of organic mulch (wood chips or shredded bark), keeping mulch an inch away from the stems to prevent rot and encourage root insulation.

During the first growing season, water FlowerFull® with roughly 1″ of water per week (rainfall plus supplemental irrigation) to establish a robust root system.

Care and Maintenance

• Watering: Maintain even moisture throughout the flowering period. Drip irrigation or soaker hoses are ideal to keep foliage dry and minimize disease risks.

• Fertilization: In early spring, apply a balanced, slow-release shrub fertilizer according to package directions. A light follow-up feeding in midsummer can boost late-season bloom if needed.

• Mulch Renewal: Refresh mulch in spring to suppress weeds, retain soil moisture, and regulate temperature.

• Pest & Disease Management: FlowerFull® offers strong resistance to common hydrangea diseases, including powdery mildew. Good spacing (at least 4′ apart) and air circulation further reduce disease pressure.
