The Queen Mum Agapanthus stands apart from the solid-blue crowd with its bicolor white-and-violet blooms that command attention in any border or container. Getting a healthy, true-to-name specimen that will actually flower in your garden, however, requires knowing exactly which rooted plant and which seller delivers on the promise of those signature blooms.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. For this guide, I cross-referenced multiple vendor listings, analyzed customer feedback for consistency on bloom color and plant health, and dug into the shipping and hardiness details that separate a thriving perennial from a disappointing clump of leaves.
After filtering through the available options, I’ve identified the live specimens that give you the best shot at those striking bicolor flower heads. Keep reading for my research-backed picks for the best queen mum agapanthus plants you can order right now.
How To Choose The Best Queen Mum Agapanthus Plants
Selecting a Queen Mum Agapanthus isn’t as simple as grabbing the first listing with “Lily of the Nile” in the title. The bicolor white-and-violet flower is the defining trait of this specific cultivar, and not every seller ships a plant that will produce it reliably. Pay attention to three things: the size of the root system at delivery, the seller’s reputation for shipping live perennials, and whether the plant is mature enough to bloom in its first season.
Container Size and Maturity at Arrival
A starter plug in a 3-inch pot may take a full growing season or more before it throws its first flower stalk. A plant in a 1-gallon or 1.5-gallon container, by contrast, often has a well-developed root mass and multiple fans of foliage, giving it a much higher chance of blooming in the same year you plant it. If you want those signature bicolor umbels this summer, choose a larger pot size and confirm the listing states the plant’s approximate height and spread at the time of shipping.
Hardiness Zones and Overwintering Strategy
Queen Mum Agapanthus is reliably hardy outdoors only in USDA zones 8a through 10b. Gardeners in zone 7 can push the boundary with heavy winter mulch, but anyone colder should plan to overwinter the plant indoors in a container. Always check that the seller ships to your specific state — some vendors are restricted from shipping live plants to Arizona or California due to agricultural regulations, so read the shipping fine print before you buy.

In‑Depth Reviews
1. Queen Mum Agapanthus (1.5 Gallon)
Southern Living’s Queen Mum Agapanthus is the only option on this list that ships the specific bicolor white-and-violet cultivar in a mature 1.5-gallon container. That larger pot size means the root system is already well-established, which dramatically increases the likelihood of seeing flower stalks in the first growing season rather than waiting a year or more for a starter plug to catch up.
At 12 pounds shipping weight, this plant arrives with substantial top growth — multiple fans of strap-like foliage that can fill a 18-inch pot immediately. The customer reviews consistently mention healthy leaves and vigorous growth after planting, with several reports of blooms appearing within weeks of arrival. The warranty covers replacement if the plant arrives dead or damaged, but the packaging is robust enough that most shipments arrive in excellent condition.
The main limitation is that this premium perennial is only reliably hardy in zones 8a-10b, and the seller cannot ship to every state due to live-plant regulations. If you live within its hardiness range and want the truest expression of the Queen Mum’s bicolor bloom pattern without waiting for a small plant to mature, this is the definitive pick.
What works
- Large 1.5-gallon root mass for first-year blooms
- Authentic bicolor white-and-violet flowers
- Healthy foliage and strong growth reported by buyers
What doesn’t
- Limited to zones 8a-10b for outdoor overwintering
- Premium price tier for a single plant
2. White African Iris 1 Gallon
While not a true Agapanthus, the White African Iris (Dietes bicolor) delivers a very similar aesthetic with grass-like foliage and dainty white flowers accented by violet markings. It ships in a full 1-gallon container, giving it instant landscaping presence. The 10-pound shipping weight indicates a solidly rooted plant that can fill a border edge or fence line quickly.
Customer feedback is overwhelmingly positive, with multiple 5-star reviews praising the plant’s health upon arrival and the detailed care instructions included. Buyers note the secure packaging that prevents soil spillage and damage during transit. The plant thrives on a simple weekly watering schedule and full sun, making it nearly foolproof for gardeners who want fast ground coverage.
The downside is that this is not a bicolor Queen Mum — the blooms are predominantly white with small purple marks, rather than the bold white-and-violet contrast of the true cultivar. It also cannot ship to Arizona or California due to agricultural restrictions. But for under , you get a vigorous, low-maintenance shrub that looks similar and establishes much faster than a starter-sized plug.
What works
- Large 1-gallon size ready for immediate planting
- Extremely easy care with weekly watering only
- Excellent packaging and shipping reliability
What doesn’t
- Not a true Agapanthus cultivar
- Does not ship to Arizona or California
3. Blue Agapanthus 1 Gallon
This 1-gallon Blue Agapanthus from PERFECT PLANTS delivers the classic deep blue flower clusters that made Agapanthus famous. It’s a solid choice if you want the traditional blue look rather than the bicolor Queen Mum, and the 1-gallon container offers a mature plant that can serve as a border accent or specimen plant right away. The manufacturer specifies it grows well in zones 8-10 and should be planted in early spring for best results.
Customer reviews are consistently high, with buyers calling the plant “beautiful” and “better than expected.” The plant arrives with strong green foliage and a healthy root system, though a minority of reviewers note that the first season may produce leaves only, with blooms appearing the following year. The blue flower clusters are aromatic and rebloom throughout spring into early summer, providing a long season of color.
The biggest drawback is the color — this is a solid blue Agapanthus, not the bicolor Queen Mum. If you specifically want the white-and-violet contrast, this won’t deliver it. Also, some buyers reported a lack of flowers in the first year, suggesting the plant may need a season to establish before putting on its full show.
What works
- Classic deep blue flower clusters that rebloom
- Mature 1-gallon size with strong root system
- Aromatic flowers add sensory appeal to the garden
What doesn’t
- Solid blue color, not bicolor Queen Mum
- Some plants may not bloom in the first season
4. Agapanthus ‘Lily of The Nile’ (2-Pack)
Wellspring Gardens offers this 2-pack of Agapanthus starter plants in 3-inch pots, making it the most budget-friendly entry point for gardeners who want multiple plants. The listing specifies that each pot contains 2-3 plants that can be separated or grouped, effectively giving you 4-6 individual starts for the price. The starter plants arrive at 3-8 inches tall and are GMO-free, suited for zones 7-10.
The customer reviews are mixed, which is typical for starter-sized perennials. Several buyers report healthy plants that grow well after a couple of months, while one reviewer noted the plant died within two days and the seller was unresponsive. The small size means you’ll need patience — expect a full season of foliage growth before these plants are large enough to produce flower stalks.
This is a decent option if you want to fill a larger area on a tight budget and don’t mind waiting. Just be aware that the starter size carries more risk during shipping, and the plant may not match the lush image in the listing for several months. It’s best suited for experienced gardeners who are comfortable nurturing young perennials through their first season.
What works
- Lowest cost per plant for filling larger areas
- Multiple plants per pot can be separated
- GMO-free with clear care instructions
What doesn’t
- Small starter size delays first blooms significantly
- Inconsistent shipping survival reported by some buyers
5. Agapanthus Africanus (3 Plants)
Florida Foliage sends three Agapanthus Africanus plants in 2-inch pots, which is the smallest container size on this list. The advantage is quantity — three separate starts give you flexibility for mass planting or creating a clump effect over time. The listing describes robust growth in various soil types and adaptability to sun or partial shade, making it a forgiving choice for less-than-ideal garden spots.
Customer feedback is very mixed. The positive reviews highlight excellent packaging with spray foam that keeps soil moist and plants alive during transit, with one buyer successfully splitting a 40-plant order into 52 separate starts. On the other hand, several reviewers report that the plants never bloomed, grew very slowly, or simply didn’t survive — one attributed the failure to a cold winter, while another noted the plants remained small and never matched the photo. The 2-inch pot size is extremely small, so these are true starter plugs that require careful nurturing.
This is the most budget-conscious option for quantity, but the risk of non-performance is higher. If you’re a patient gardener who wants to experiment with mass planting on a budget and has the time to baby small starts, it’s a gamble worth taking. If you want guaranteed blooms this season, invest in a larger container size instead.
What works
- Three plants for the price, great for mass planting
- Excellent packaging with moisture-retaining foam
- Adaptable to sun or partial shade
What doesn’t
- Very small 2-inch starter plugs require patience
- Inconsistent blooming and slow growth reported
Hardware & Specs Guide
Container Size and Root Mass
The size of the pot a Queen Mum Agapanthus ships in directly correlates with its maturity and first-year bloom potential. A 1.5-gallon container, like the Southern Living cultivar, holds a root system that is roughly 12-18 months old — enough to support multiple flower stalks in the first growing season. Starter plugs in 2-inch or 3-inch pots, by contrast, are only a few months old and may need a full year of vegetative growth before they have enough energy stored to produce bloom stalks. The weight of the shipping package gives a good clue: 12 pounds indicates a substantial root ball, while lighter packages suggest immature starts.
Hardiness Zones and Cold Tolerance
Queen Mum Agapanthus (Agapanthus praecox orientalis ‘Queen Mum’) is rated for USDA zones 8a through 10b. The plant can tolerate occasional light frost, but prolonged temperatures below 20°F will kill the root system if left unprotected. Gardeners in zone 7 can overwinter it with heavy mulch or by moving containers into a protected garage, but anyone in zone 6 or colder should treat it as an annual or overwinter it indoors. The Southern Living cultivar specifically warns that the buyer assumes risk for shipping during extreme weather, so order in spring or fall for best results.

Final Thoughts: The Verdict
