The search for a true statement piece in the tropical garden often ends in frustration when plants fail to deliver the promised leaf size or color intensity. Blue Hawaii Colocasia stands apart with its powder-blue stems and large, heart-shaped leaves that create a structural focal point you simply cannot achieve with standard elephant ears.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I have spent years comparing propagation stock, analyzing root-zone requirements, and cross-referencing owner reports across dozens of colocasia cultivars to identify the specimens that actually thrive in home gardens.
Whether you are filling a rain garden border or designing a bold container display, choosing the right blue hawaii colocasia means understanding bulb viability, dormancy handling, and the specific moisture regimen that separates a showpiece from a disappointment.
How To Choose The Best Blue Hawaii Colocasia
Colocasia esculenta ‘Blue Hawaii’ is prized for its powdery blue petioles and vigorous clumping habit, but not all plants sold under this name deliver on that promise. The buying decision comes down to three factors that separate a thriving specimen from a disappointing bulb.
Bulb Condition and Sizing
Live bulbs arrive dormant and should feel firm with no soft spots. A bulb smaller than a golf ball in diameter may take an extra season to reach full leaf size. Look for suppliers that guarantee a minimum bulb circumference and ship with breathable packaging to prevent moisture buildup that triggers rot during transit.
Stem Color Authenticity
True Blue Hawaii Colocasia develops its signature blue-gray stem coloration only under adequate light and consistent moisture. Many generic elephant ear bulbs are mislabeled as Hawaiian varieties. Verified growers will specify Colocasia esculenta ‘Blue Hawaii’ on the label and often show photos of mature plants with visible powder-blue petioles.
Hardiness and Overwintering Strategy
Blue Hawaii is hardy in USDA zones 8 to 11 but must be lifted and stored dormant in colder regions. The bulbs require temperatures above 50°F during active growth and a dry dormancy period below 60°F to reset for the next season. Suppliers that provide zone-specific planting guides reduce the risk of losing bulbs to winter kill.

In‑Depth Reviews
1. Live Colocasia – Pharaoh’s Mask
Pharaoh’s Mask arrives as a live plant in a 1.76-quart nursery pot with an established root system and multiple pups, giving it a growth head start of several weeks over bare bulbs. The glossy green leaves display dark purple raised veins and sturdy dark purple stems that create a dramatic 3D effect in shaded borders. At maturity it reaches 4 feet tall and requires at least 3 feet of horizontal space, making it a solid anchor plant for tropical beds.
Shipping stress causes leaf damage on arrival, but the bulb is resilient — cutting damaged foliage back to the tuber triggers vigorous regrowth within days. Multiple owners report finding 7 or more healthy pups in the pot, which can be separated and propagated for additional plants. The supplier ships directly from a greenhouse and provides care instructions for overwintering in colder zones.
This is not a Blue Hawaii cultivar, but it shares the same Colocasia growth habits and moisture requirements. For buyers seeking guaranteed stem color and immediate garden impact, the established root system outweighs the risk of shipping damage that comes with bare bulbs.
What works
- Established roots with multiple pups reduce establishment time
- Sturdy purple stems and veining provide instant structural contrast
What doesn’t
- Leaves often arrive damaged due to shipping stress
- Not labeled as Blue Hawaii — verify stem color expectations
2. LIVE BULBS Colocasia gigantea Thailand Giant 6 Bulbs
This six-bulb pack from Greenhouse PCA targets gardeners looking to fill larger areas quickly with massive elephant ear foliage. The bulbs are listed as Colocasia gigantea Thailand Giant, a variety known for leaves that can exceed 4 feet in length under ideal conditions. The pack ships as dormant bulbs suitable for outdoor planting in sandy soil with partial sun exposure.
Owner experiences are sharply divided. Multiple buyers report poor packaging that allows bulbs to fall out during transit, and several note that only 2 out of 6 bulbs sprouted by mid-spring. Conversely, other owners report fast emergence and vigorous growth once planted. The bulbs are GMO-free and marketed for air purification, though the primary appeal remains the massive leaf display rather than environmental benefits.
For the buyer seeking high bulb count at a low per-unit cost, this pack offers volume. But the mixed germination reports and mislabeling complaints mean you should inspect bulbs on arrival and be prepared to request replacements for non-viable specimens.
What works
- Six bulbs provide extensive ground coverage potential
- Bulbs that sprout produce very large leaves quickly
What doesn’t
- Packaging allows bulbs to fall out or arrive broken
- Inconsistent germination — some buyers lose most bulbs
3. 3 Live Bulbs Colocasia gigantea Thailand Giant
This three-bulb pack offers the same Thailand Giant genetics as the six-bulb version but at a lower entry cost, making it suitable for gardeners who want to trial the cultivar before committing to a larger planting. The bulbs are labeled as heirloom and ship at 0.5 pounds total weight, with partial sun and sandy soil listed as preferred growing conditions.
Customer feedback reveals two recurring problems: bulbs arriving soft and mushy after only two weeks in potting soil, and plants that fail to emerge at all after 2.5 months in the ground. Owners who had success report 5-star outcomes with plants establishing quickly and looking “very nice” in front-of-house beds. The inconsistency appears tied to storage conditions during shipping rather than the bulbs themselves.
If you want to test whether this giant strain works in your microclimate without investing in a full six-pack, this is the logical starting point. Just be prepared for a 50-50 chance of full germination and factor in the cost of replacing non-viable bulbs.
What works
- Lower bulb count reduces upfront cost for trial planting
- Heirloom genetics appeal to seed-saving growers
What doesn’t
- High incidence of bulb rot within 2 weeks of planting
- Multiple reports of zero emergence after extended periods
4. Blue Butterfly Bush – Clerodendrum myricoides
The Blue Butterfly Bush is not a colocasia, but it is the ideal companion plant for a Blue Hawaii-themed tropical bed. Its uniquely shaped blue flowers resemble butterflies in flight and bloom from spring through fall, providing pollinator activity that complements the bold foliage of colocasia. The plant grows 4 feet tall with a loose, sprawling habit that softens the upright structure of elephant ears.
This starter-size plant ships in a 4-inch pot from Emerald Goddess Gardens and arrives with a well-developed root system. Owners consistently praise the careful packaging and healthy condition on arrival, with many noting that the plant thrives after repotting and begins budding within weeks. It requires 6 to 8 hours of direct light and fertile, well-draining soil to reach its full blooming potential.
This is not a plant for indoor growing due to its high light and humidity requirements. But in USDA zones 8B through 11, it becomes a reliable perennial that returns each season with minimal frost protection.
What works
- Butterfly-shaped blue flowers add unique pollinator value
- Healthy starter size arrives well-packed and establishes quickly
What doesn’t
- Not suited for indoor growing or cold climates
- Takes multiple seasons to reach full blooming maturity
5. Alocasia Plant Collection 4 Pack
This collection includes four rare Alocasia varieties — Cuprea, Mickey Mouse, Silver Dragon, and Dragon Scale — shipped as young starter plants. Alocasias are close relatives of Colocasia and share similar water and humidity preferences, making this pack a good add-on for collectors who want variety alongside their Blue Hawaii specimens. The plants ship at starter size, typically too small for a 2-inch pot, which reduces shipping stress.
Owner experiences are mixed. Buyers who received healthy plants report vibrant growth after separating pups, pruning damaged leaves, and providing bright indirect light. Others describe receiving plants that are “barely bigger than a cutting” with wilted or dying leaves on arrival, and the supplier’s refund policy has drawn criticism for requiring costly return shipping. The photos online show more color saturation than the actual plants deliver initially.
This collection suits patient indoor growers who enjoy watching plants establish from small starts. If you want immediate foliage impact for an outdoor bed, the starter size and indoor care requirements make this a less practical choice than a single established colocasia in a larger pot.
What works
- Four rare Alocasia varieties in one affordable pack
- Starter size reduces shipping stress and acclimates well
What doesn’t
- Plants arrive very small — not suitable for instant outdoor display
- Inconsistent health on arrival; difficult return process
Hardware & Specs Guide
Bulb Viability and Storage
Colocasia bulbs shipped dormant should be firm with no soft spots. Bulb rot occurs when moisture is trapped in a non-breathable package during transit. Upon arrival, unbox immediately and air-dry for 24 hours if any condensation is present. Store bulbs in a cool, dark place above 50°F until planting time. Bulbs smaller than a golf ball will take two seasons to reach full leaf size, so prioritize bulbs that measure at least 2 inches in diameter.
Stem Color Genetics
The signature powder-blue petiole of Colocasia esculenta ‘Blue Hawaii’ is a stable cultivar trait, not a variable nursery mutation. If the supplier does not explicitly name the cultivar as ‘Blue Hawaii’ and provide an image showing blue stems at maturity, the bulbs may produce green-stemmed plants. Some sellers use “blue” to describe leaf color rather than stem color, which causes confusion. Verify the scientific name and request photos of the supplier’s mother stock before ordering.
Soil Moisture Management
Blue Hawaii colocasia requires consistently moist soil during active growth but cannot tolerate waterlogged conditions that cause bulb rot. The ideal soil mix is 50% garden loam, 30% perlite, and 20% composted bark. This blend retains enough moisture for the high water demand of large leaves while providing drainage channels that protect the bulb. In containers, use pots with drainage holes and add a 1-inch layer of gravel at the bottom to prevent root zone saturation.
Hardiness Zone Strategy
Colocasia esculenta ‘Blue Hawaii’ is reliably perennial in USDA zones 8 through 11. In zones 7 and below, the bulb must be lifted after the first frost and stored dormant in dry peat moss or vermiculite at 45°F to 55°F. Do not store bulbs in soil or allow them to freeze. Gardeners in zones 6 and colder often treat colocasia as an annual or overwinter in containers brought indoors to a bright, cool room with reduced watering from November to March.
