🖤 Dark, almost-black purple flowers • ✨ Satiny petals • 🌿 Sturdy 40–50 cm stems • 🌤️ Flowers in April • 💐 Beautiful in bouquets • ☀️ Full sun • ❄️ Fully hardy • 📏 Bulb size 11/12
The black Triumph tulip is one of the most striking tulips in the garden: in April, its cup-shaped flowers, a purple so dark it looks black, open on straight 40–50 cm stems, with satiny petals that take on plum tints in the sun. It is a horticultural selection from Europe (the Netherlands), from the Triumph group of tulips, known for their strong stems and long-lasting flowers.
Planted alone in a large pot or mixed with white or pink flowers, it adds a sought-after dark, elegant touch. Among our flower bulbs, it is the tulip for contemporary borders and refined bouquets.
Which tulip should you choose?
- Black Triumph tulip (this plant) — a single color, almost-black purple, 40–50 cm, in April. For a striking look and elegant combinations.
- Mixed Darwin tulips — red, yellow, pink and orange, 50–60 cm, large flowers up to 10 cm in April and May. For a colorful, cheerful border.
- White Triumph tulip — pure white, 40–50 cm, in April. For a bright garden and a black-and-white contrast.
- Tulipa praestans — botanical, 20–30 cm, 3 to 5 flowers per bulb in March and April. For pots, rockeries and a garden that flowers again on its own.
- Mixed double tulips — full, peony-like flowers, 40–50 cm, in April and May. For a romantic border and generous bouquets.
Planted together, the black and the white flower at the same time and at the same height: the contrast is stunning in borders and pots alike.
How many bulbs do you need?
Tulips look best planted in tight groups: allow about 40 bulbs per square meter, or 10 to 12 bulbs in a pot 30 cm across.
- 12 bulbs: one large pot on a patio, or a small group in a border.
- 24 bulbs: two large pots, or about 0.5 m² in the ground.
- 48 bulbs: about 1 m², for a dark, elegant border.
- 96 bulbs: about 2 m², for a spectacular edging or tulips to cut all through April.
The bigger the pack, the lower the price per bulb: the 96-bulb pack works out at less than half the price per bulb of the 12-bulb pack.
Planting & position
Plant tulips from October to December, once the soil has cooled, for flowers in April.
- Position: full sun; the light makes the satiny petals shine and brings out their plum tints.
- Depth: 15 cm, pointed end up.
- Spacing: 10 cm between bulbs in the ground, 3 to 5 cm in pots.
- Soil: well drained; add sand to heavy soil, as the bulb rots in waterlogged ground.
- Hardiness: down to -25 °C in the ground, no protection needed.
Plant it in front of a light background (a white wall, silver foliage, blond grasses): its dark color stands out far better than next to a dark hedge.
Watering & care
In the ground, rain is enough. In pots, use a free-draining compost, as explained in our guide to composts and growing media, and water when it is dry on the surface.
- Watering: low — at planting, then in pots when the potting mix is dry on the surface, especially while the buds are forming.
- Feeding: not needed in the ground; in pots, a bulb fertilizer as the leaves appear.
- Faded flowers: cut the flower off just below the head as soon as it drops its petals, leaving the stem and leaves.
- After flowering: let the foliage turn yellow where it is for six weeks; it rebuilds the bulb’s reserves.
Bulbs tire faster in pots: plant them out in the garden after flowering and put fresh bulbs in the pot in autumn.
Styling ideas & plant pairings
Its dark color goes beautifully with white, pink and purple, in borders and on sunny balconies alike, as shown in our guide to plants for a sunny balcony.
- For a black-and-white contrast, plant it with Narcissus 'Thalia' — they flower together in April, and the pure white brings out the depth of the purple.
- For a carpet at its feet, add Armenian grape hyacinths — their vivid blue spikes light up the base of the tulips.
- To carry on the purple tones, pair it with Allium 'Purple Sensation' — its purple globes take over in May.
- For a patio version, plant 10 to 12 bulbs in the white Elho Greenville Round pot in the Ø30 cm size — the white sets off the almost-black flowers.
In a pot, plant in layers: tulips at the bottom, 15 cm deep, and grape hyacinths on top, 7 cm deep, for a pot that turns blue and then black from March to late April.
Verdeia tips
- Wait for the soil to cool: ideally plant from late October. In soil that is still warm, tulip bulbs are more prone to disease.
- Cut them in bud for the vase: pick tulips in the morning, when the bud is colored but still closed. With white or pink flowers they make a very chic bouquet, as shown by our ideas for plants to give as gifts.
- Add a few bulbs every autumn: tulips flower again, but the blooms get smaller over the years. A few fresh bulbs each year keep a border well filled.

Our Verdeia commitments
FAQ – Everything to know before adopting your Verdeia plant
How are my plants prepared before shipping?
All our plants are selected from our European partner nurseries. Before shipping, they are watered, cleaned, and protected with breathable, secure packaging. Each package is designed to ensure your plant arrives in perfect health, without any transport-related stress.
Will the plant look exactly like the photo?
The photos accurately represent the variety and the stated size. Since each plant is unique, slight differences in shape, foliage, or color may occur — and that’s part of their charm.
What are the delivery times and conditions?
Orders ship within 48 working hours, with tracked delivery in 2 to 5 working days via DPD. Shipping costs and the free-shipping threshold depend on your country — see our delivery page. You receive a tracking link as soon as your parcel leaves.
What should I do when my plant arrives?
Open your package as soon as you receive it and carefully remove the plant from its packaging. Let it acclimate for 24 hours in its new environment before watering. If it has been slightly stressed during transport, it will recover its shape after one or two days in the light.
What should I do if my plant arrives damaged?
Contact us within 48 hours with a photo of the issue. Our team will assess the situation and offer you the best solution: replacement, partial refund, or recovery advice.
Can I return a plant?
Since plants are living beings, standard returns are not possible. However, we guarantee good health upon delivery: if the plant arrives damaged, it will be replaced free of charge. For any other cases (order error, decorative pot, accessory), returns are possible within 14 days.
