A crepe myrtle with black leaves isn’t a gimmick — it’s a genetic shift that turns the standard green canopy into a deep, near-charcoal backdrop. The payoff is a color contrast standard varieties can’t touch: violet, crimson, or pure white blooms against foliage so dark it reads almost black from ten paces.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I spend my time comparing cultivar genetics, analyzing soil and sun tolerance data across USDA zones, and cross-referencing hundreds of verified owner experiences to separate the living plants that thrive from those that ship half-dead.
This guide breaks down five of the top-rated live specimens on the market, each selected for bloom intensity, root establishment, and true black-leaf genetics. Whether you want a single accent tree or a matched pair for a bold entryway, this roundup of the best black leaf crepe myrtle options gives you the facts to choose without the guesswork.
How To Choose The Best Black Leaf Crepe Myrtle
Black leaf crepe myrtles — almost always sold under the Black Diamond series — are distinct from standard crepe myrtles in one critical way: their foliage contains higher anthocyanin levels, which produce the dark, almost black leaf color that makes the flowers pop. Choosing the right tree means understanding bloom color, pot size, regional limitations, and where you plan to plant it.
Bloom Color and Landscape Contrast
The whole point of a black leaf myrtle is the contrast. Purely Purple delivers a deep violet flower against the dark leaf, creating a moody, dramatic look. Crimson Red gives a fiery pop that stands out even from across the yard. Crystalline White offers the highest contrast — the white petals against black foliage is a showstopper in evening gardens. Pick the color that complements your existing hardscape and neighboring plants.
Pot Size and Transplant Maturity
Most black leaf crepe myrtles ship in 1-gallon or 3-gallon nursery pots. A 1-gallon tree typically arrives 12–18 inches tall and needs a full season to establish before it puts on significant height. A 3-gallon tree, at 1–2 feet or more, has a larger root ball and a head start on growth, often reaching 6–8 feet by the second year. If you want faster visual impact, the larger pot size is worth the extra investment.
Shipping Restrictions and Hardiness
Agricultural laws prevent shipping live crepe myrtles to California, Arizona, Alaska, and Hawaii due to pest and disease control. If you live in those states, your order will be refunded and canceled. These trees thrive in USDA zones 6–9, need full sun (at least 6 hours daily), and prefer well-draining loam soil. They are drought-tolerant once established, but regular watering during the first growing season is critical for root development.

In‑Depth Reviews
1. American Plant Exchange Black Diamond Purely Purple (3 gal)
This is the largest option in our lineup — a 3-gallon pot holding a tree that arrives 1–2 feet tall with a root system already dense enough to handle full sun transplantation immediately. The American Plant Exchange branding comes with verified organic soil material and an ASPCA pet-friendly rating, which matters if your planting spot is near a dog run or a cat’s favorite sunbathing zone.
The Purely Purple blooms are true to the Black Diamond genetics: deep violet flowers that hold their color from late spring through the first frost. The 3-gallon root ball gives this tree a full growing season head start over 1-gallon competitors, meaning you can expect 4–6 feet of height by the end of year two. It’s drought-tolerant once established, but requires regular watering through the first summer to push those roots deep.
Partial shade is listed as acceptable, but full sun (6+ hours) produces the densest black leaf coloration. The extended bloom time advertised is real — these trees flower continuously rather than in one heavy flush, giving you color from June through October in most zones.
What works
- Largest pot size offers fastest establishment and growth
- ASPCA verified as pet-safe, rare for dark-foliage ornamentals
- Continuous blooms from late spring through fall
What doesn’t
- Price is the highest in the roundup for a single tree
- Cannot ship to CA, AZ, AK, or HI
2. Crimson Red Black Diamond Crape Myrtle (2 Trees)
If you’re planning a symmetrical entrance, a pair of these Crimson Red Black Diamond trees delivers a matched look from day one. Each arrives in a 1-gallon pot at 12–18 inches tall, and the two-trees-in-one-purchase format saves you from trying to find a second matching specimen later — a real headache with specialty cultivars.
The crimson bloom is intense: a true fire-engine red that appears almost fluorescent against the near-black foliage. These trees ship from Simpson Nursery and follow the same Black Diamond genetics that produce the dark leaves. Because they are 1-gallon starters, expect a slower first year compared to 3-gallon options, but planting them two feet apart creates a dense, hedge-like effect within two seasons.
The combined weight of 10 pounds for both trees means the root systems are healthy and moist-packed at shipment. Just be aware that these cannot ship to CA, AZ, AK, or HI, and they need full sun to maintain the dark leaf color — partial shade will cause the leaves to fade toward a dark green.
What works
- Two identical trees for perfect symmetrical planting
- Dramatic crimson-on-black color contrast
- Good root system weight for 1-gallon pots
What doesn’t
- Slower first-year growth compared to 3-gallon specimens
- Does not ship to four states
3. Black Diamond Crape Myrtle Tree (Crystalline White, 3 gal)
White flowers against black leaves create the most dramatic visual contrast of any color variant in the Black Diamond series. This Crystalline White specimen ships in a 3-gallon pot and reaches an expected mature height of 12 feet — the tallest potential of any tree in this roundup, making it the best candidate for a standalone focal point in a front yard bed.
The bloom period runs from summer through fall, and the extended bloom time feature means the white flowers keep coming even as the nights get cooler. The soil requirement is specifically loam, and the tree demands full sun — this is not a variety that tolerates shade well. The 15-pound shipping weight confirms a dense, well-established root ball that can handle transplant shock better than lighter 1-gallon options.
Simpson Nursery ships this tree, and the Crystalline White name is accurate: the petals are a clean, pure white without any cream or pink undertones. This is the variety to pick if you want a moonlit garden effect — the white blooms practically glow at dusk against the dark foliage.
What works
- Highest contrast bloom-to-leaf color ratio in the lineup
- Large 3-gallon pot with heavy root ball for fast establishment
- Matures to 12 feet for a substantial landscape presence
What doesn’t
- Requires full sun — partial shade will wash out black leaf color
- Cannot be shipped to CA, AZ, AK, or HI
4. American Plant Exchange Black Diamond Purely Purple (1 gal)
This is the entry-level version of the same American Plant Exchange Purely Purple variety that tops our list — but in a 1-gallon pot at 1–1.5 feet tall. It carries the same ASPCA pet-safe certification and the same Purely Purple bloom color, just without the head start that comes from the larger 3-gallon container.
For gardeners on a budget or those who want to test whether a black leaf crepe myrtle thrives in their microclimate before committing to a larger investment, this is the smart play. The drought tolerance and low-maintenance requirements are identical to the 3-gallon version, and the year-round expected bloom period means you’ll get flowers from spring through fall even in the first season if planted early enough.
Partial shade is acceptable but not ideal. The biggest trade-off is patience — this tree will need a full extra growing season to reach the size the 3-gallon version delivers by year two. Pair it with balanced slow-release fertilizer in early spring to accelerate root development.
What works
- Lowest price point for the proven American Plant Exchange genetics
- ASPCA pet-safe, suitable for homes with animals
- Compact size is easier to transplant and position
What doesn’t
- Slower growth curve than the 3-gallon version
- Cannot ship to CA, AZ, AK, or HI
5. Purely Purple Black Diamond Crape Myrtle (1 gal)
This is the most affordable single-tree option in the roundup, sold under the Generic brand from Simpson Nursery. At 12–18 inches in a 1-gallon pot, it’s identical in form to the American Plant Exchange 1-gallon Purely Purple, but without the branded potting soil mix or the ASPCA certification. If the lowest upfront cost is your priority, this tree gets you the same Black Diamond genetics at the smallest investment.
The Purely Purple bloom color is consistent with the Black Diamond series — deep violet flowers that create strong contrast against the dark leaves. The 5-pound shipping weight indicates a healthy but compact root system. This tree will need full sun, regular watering through the first summer, and well-draining loam soil to reach its mature height of 10–12 feet over several years.
The absence of marketing extras means you’re paying purely for the plant — no frills, but no gimmicks either. This is the smart choice for experienced gardeners who already have their own preferred soil mix and don’t need the reassurance of a branded product. Just remember the standard shipping restriction: no CA, AZ, AK, or HI.
What works
- Lowest upfront cost for authentic Black Diamond genetics
- No-frills packaging keeps the focus on the plant itself
- True Purely Purple bloom color against dark foliage
What doesn’t
- No ASPCA pet-safety or organic soil certification
- Slowest growth trajectory due to 1-gallon starter size
- Cannot ship to CA, AZ, AK, or HI
Hardware & Specs Guide
Pot Size and Establishment Speed
The 1-gallon pot (used by products 1, 2, and 4) holds a tree with a root ball that supports 12–18 inches of top growth. These trees need a full growing season to establish before they push significant height. The 3-gallon pot (used by products 3 and 5) holds a larger root system that translates to 1–2 feet of top growth at arrival and a head start of roughly one full year in terms of mature height. If you want visible vertical growth in the first season, choose the 3-gallon container.
Bloom Color and Genetic Consistency
All five trees in this roundup are Black Diamond series cultivars, meaning the dark leaf color is bred in through high anthocyanin levels, not sprayed or dyed. The Purely Purple and Crimson Red varieties produce pigmented flowers that contrast with the dark leaves, while the Crystalline White offers the maximum visual pop. Bloom consistency across the series is reliable, but full sun is required to maintain the black leaf coloration — partial shade causes the leaves to fade to a dark green within weeks.

Final Thoughts: The Verdict
For most gardeners looking for a black leaf crepe myrtle, the winner is the American Plant Exchange Purely Purple in the 3-gallon pot because it offers the fastest establishment, continuous violet blooms, and proven pet-safe genetics in a single, high-impact tree. If you want the highest contrast in your landscape, grab the Crystalline White 3-gallon for its white-on-black visual drama. And for a symmetrical entryway on a budget, nothing beats the Crimson Red two-tree set — two identical specimens that turn a standard driveway into a statement.
