A hosta that grows up instead of out changes the entire rhythm of a shade border. While most varieties huddle in low mounds, Krossa Regal sends its blue-green, wavy leaves upward on upright petioles, creating a vase-shaped silhouette that stands over three feet tall. This structural habit makes it one of the most sought-after specimen hostas for gardeners who want vertical drama without staking.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years studying perennial market trends, analyzing grower specifications, and cross-referencing thousands of owner reports to understand which bare-root shipments actually deliver on their genetic promise.
Finding a true krossa regal hosta from an online nursery means verifying that the roots are firm, the crown is intact, and the cultivar’s signature upright growth habit was maintained during division. This guide evaluates five bare-root offerings to help you choose the right start for your landscape.
How To Choose The Best Krossa Regal Hosta
Krossa Regal is not a generic hosta plug. Its upright vase shape and thick blue-green leaves mean that root structure, crown size, and genetic fidelity matter more than with bulk mixed bags. Three factors separate a thriving specimen from a disappointment.
Crown Size and Root Mass
A bare-root Krossa Regal should show at least one clearly visible crown with multiple dormant buds and a cluster of fleshy storage roots at least four inches long. Thin, single-strand roots with no crown division will take two full seasons to establish an upright habit. Look for listings that specify “jumbo” or “number 1” size roots rather than generic small divisions.
Genetics and Growth Habit Verification
Growers who specialize in named cultivars typically sell true-to-type divisions. Bulk mixed hosta bags often contain random green or gold varieties, not the specific upright blue-green form. If the listing doesn’t say “Krossa Regal” in the style name or product title, assume you’re getting a generic large hosta mix. Eden Brothers and specialty perennial farms are more reliable than unbranded bundles for genetic accuracy.
Hardiness Zone Expectations
Krossa Regal performs reliably in zones 3 through 9. In zone 8 or 9, the plant may need afternoon shade to prevent leaf scorch and maintain its blue wax coating. Northern growers should check that the roots arrive dormant and un-sprouted for spring planting. Roots that have already pushed green growth during shipping often suffer transplant shock if soil temperatures are still cold.

In‑Depth Reviews
1. Eden Brothers Krossa Regal Hosta Roots
This is the only product in the lineup that ships as a named Krossa Regal division rather than a mixed hosta assortment. Each order contains four bare-root divisions with visible crowns, and the grower specifically maintains the upright parent stock during division. Multiple verified buyers reported sprouting within days and producing lavender flowers in the first season — a strong sign that the roots were mature enough to bloom immediately rather than spending a full year building energy.
The wavy, thick leaves that define Krossa Regal’s slug resistance were confirmed by owners who noted no leaf damage through wet summers. The vase-shaped habit began emerging by mid-season in most reports, with the tallest leaves reaching over 30 inches by the second year. Eden Brothers backs the product with zone 3 through 9 coverage, making it viable for both northern shade gardens and southern woodland settings with afternoon protection.
The primary risk is root size variability within the pack. One verified review received a root so small it was difficult to locate during planting, and another felt the “4-count” description implied larger individual roots than what arrived. Still, the overall germination rate and growth speed among buyers was exceptionally high, and the genetic accuracy of the cultivar eliminates the guesswork of mixed bags.
What works
- True Krossa Regal genetics with upright habit preserved
- Fast sprouting — leaves visible within 48 hours in many reports
- Lavender blooms in first season confirm mature root stock
What doesn’t
- One root per pack may be significantly smaller than others
- “4-count” phrasing may set higher size expectations than delivered
2. Holland Bulb Farms Mixed Hosta Value Bag
Holland Bulb Farms delivers six number-1-sized bare-root divisions that are notably larger than the standard retail bare root. Multiple buyers described the roots as “jumbo” and reported visible growth within four days of planting. The listing specifies a mature height of 12 to 24 inches with a spread of 32 to 36 inches, matching the dimensions of a well-established mixed hosta clump. This is not a single-cultivar purchase, but the root quality is consistently high.
The key advantage here is root size and count per dollar. Each root arrives with multiple eyes (dormant buds), so the first-year foliage density is higher than with smaller divisions. Buyers in zones 7 through 10 reported strong performance in partial shade, and even skeptical first-time online bulb purchasers were impressed by the vigor five weeks after planting.
The main trade-off is genetic variety. You get a mix of green shades, not a named cultivar. One buyer received only four roots instead of six, and another reported complete die-off, though this was an outlier. For gardeners who want a quick, full-looking hosta border rather than a specific upright specimen, this bag delivers excellent root mass and rapid establishment.
What works
- Jumbo root size with multiple eyes for fast first-year spread
- Visible growth within days for impatient gardeners
- Wide zone range extends viability to deep south
What doesn’t
- Mixed varieties only — no Krossa Regal or named cultivar
- Occasional short count or complete failure reported
3. Blue Angel Hosta Bareroot (5-Pack)
Blue Angel is a legitimate large blue hosta cultivar that shares Krossa Regal’s blue leaf color and slug resistance but grows in a mounding form rather than an upright vase. This five-root pack from Daylily Nursery has drawn consistent praise for root quality and rapid establishment. Multiple buyers noted that the roots arrived firm, planted easily, and produced visible leaves within days. One reviewer shared that after one year, the plants had become large blue specimens that drew compliments from gardening neighbors.
The 18-inch mature height with a 32- to 36-inch spread makes this a good choice for filling mid-border space with blue foliage. The organic material tag and moisture-care instructions suggest the roots are minimally processed, which helps them acclimate quickly. Buyers in zones 3 through 8 reported reliable overwintering, though one reviewer in zone 8 noted that full-sun exposure caused the blue wax to fade toward green by midsummer.
The biggest limitation for Krossa Regal seekers is growth habit — Blue Angel mounds rather than towers. If you need a tall upright focal point, this won’t replace a true Krossa Regal. But if you want a large, fast-spreading blue hosta that establishes quickly and multiplies reliably, the five-root count at this price point is hard to beat.
What works
- Fast establishment — leaves visible within days in most reports
- True blue color maintains well in shade
- Generous 5-root count for the price tier
What doesn’t
- Mounding habit, not upright like Krossa Regal
- Blue wax fades in full sun exposure
4. Gardening4Less 9-Pack Hosta Bare Root
This 9-pack from Gardening4Less offers the highest root count in the lineup, making it the obvious choice for covering large shaded areas on a tight budget. The listing does not specify a cultivar — these are mixed green hostas with purple and white flower stalks — but buyers consistently rate the packaging and root condition highly. Multiple verified purchases noted that all nine roots arrived moist, already sprouting, and took off immediately after planting.
The sandy soil specification and full-sunlight exposure claim are peculiar for hostas, which prefer shade, but the USDA hardiness zone 3 rating confirms cold tolerance. Most buyers planted them in partial to full shade and reported rapid expansion within a week. The value proposition is simple: you get nine separate hosta starts for roughly the same cost as four named-cultivar roots.
The trade-off is complete anonymity in genetics. You won’t get Krossa Regal’s upright habit, blue color, or slug-resistant leaf texture from this pack. These are generic hosta divisions that will produce green leaves and lavender or white flowers. For gardeners who just want hosta ground cover at the lowest per-plant cost, this pack works well. For anyone seeking a specific specimen, it won’t satisfy.
What works
- Highest root count for mass ground cover at lowest per-plant cost
- Roots arrive moist and often pre-sprouted for quick establishment
- Strong cold hardiness rating for northern zones
What doesn’t
- No named cultivar — green leaves only, no blue or upright habit
- Full-sun labeling contradicts typical hosta shade requirements
5. Giant Hosta Mix (3 Roots)
GardeningProducts4Less markets this as “among the world’s largest hosta” with claims of 60-inch width and 36-inch height. The blue-green and yellow-green variegated leaves are described as slug resistant due to their thick substance, and the white flowers are held above the foliage to attract pollinators. Three roots per order means each plant has room to reach its full mature spread without overcrowding.
Buyer reports confirm that the roots arrived in good condition with buds already pushing. One reviewer found four buds hidden within the root mass — a bonus. The plants sprouted through soil within two days and grew aggressively in their first season. The mix produces a combination of blue and yellow-green leaves, which adds visual contrast in a large shade bed.
The critical flaw is winter survival inconsistency. One verified buyer in zone 8 reported total loss after winter, suggesting the giant hosta genetics may be less cold-hardy than the listing claims. The 36-inch height claim approaches Krossa Regal territory, but without controlled genetics, the actual mature size varies widely. For gardeners in zones 3 through 7 who want fast, dramatic foliage from a small number of roots, this mix offers impressive first-season impact.
What works
- Thick, slug-resistant leaves with good substance
- Fast germination — sprouts visible in 2 days
- Blue-green and yellow-green variegation for visual contrast
What doesn’t
- Winter survival failure reported in zone 8
- Mature size varies widely due to mixed genetics
Hardware & Specs Guide
Bare-Root Dormancy and Storage
Bare-root hosta divisions are harvested during dormancy, typically in early spring or late fall. The roots should feel firm and slightly moist but not wet or mushy. If you cannot plant immediately, store them in a cool, dark place at 40–50°F with the roots wrapped in damp newspaper. Do not let them freeze or sit in standing water, which can rot the crown before planting.
Planting Depth and Crown Orientation
Hostas are sensitive to planting depth. The crown — the point where roots meet shoots — should sit at soil level, not buried deeper than one inch. For upright cultivars like Krossa Regal, orient the crown so the dormant buds face upward and the roots spread outward horizontally. Backfill gently and water thoroughly to settle the soil without compacting it.
