Bellevalia paradoxa

Bellevalia paradoxa is a small bulb from the mountain meadows of eastern Turkey and the Caucasus. It looks very much like a grape hyacinth and is often sold as Muscari ‘Paradoxum’, but the flowers are much darker: tightly packed, almost black-blue bells with a fine yellow-green rim. In April and May the sturdy spikes stand 20–25 cm tall above broad, grey-green leaves. An elegant, slightly mysterious colour in the spring border, and a good plant for bees.

In your garden

Why grow it?

  • An unusual, almost black-blue colour that gives depth to any spring planting.
  • An early bee plant in April–May.
  • Easy and hardy: plant the bulbs and they come back every year.
  • Sturdy spikes that do not flop, also useful as a small cut flower.
  • Slowly forms a clump, without spreading like some grape hyacinths.

Bellevalia paradoxa: where does it grow best?

  • Sun to light shade.
  • Well-drained soil: sand, loam or light clay, chalky is fine.
  • Normally moist in spring, dry in summer during dormancy.
  • At the front of a border, in a rock garden, in grass or among low perennials.
  • Plant in groups of 15–25 bulbs per m² for a good effect.

Goes well with

  • White tulips: The dark spikes contrast beautifully with white tulips.
  • Daffodil: Pale yellow daffodils next to the dark blue.
  • Grape hyacinth: Lighter shades of blue in the same shape.
  • Spurge: The fresh yellow-green of Euphorbia polychroma echoes the edge of the flowers.
  • Lady’s mantle: Soft leaves that later hide the dying bulb foliage.

Maintenance

Bellevalia paradoxa: when and how to plant it?

Plant in September–November.

  1. Plant the bulbs in September–November.
  2. Set them 8–10 cm deep, tip upwards, 5–8 cm apart.
  3. In heavy soil, put a handful of grit under the bulbs for drainage.
  4. Plant in loose groups rather than rows.
  5. Water after planting if the soil is dry.

Care

Water
Rarely needed; natural rain in spring and autumn is enough.
Feeding
Some compost in autumn is enough.
Leaves
Let the leaves yellow naturally after flowering: the bulb draws strength from them for next year.
Faded spikes
Cut them off if you do not want seed; leave them to let it self-sow.
Dormancy
In summer the bulb rests in dry soil; do not overwater.

Tip: Plant them in a group among white or cream tulips: the almost black spikes make the white glow even more.

Bellevalia paradoxa: when to prune it?

When: No pruning is needed.

How:

  • Cut off faded spikes if you want to prevent seeding.
  • Remove the leaves only when they are completely yellow or brown, usually in June.

Caution: Do not cut the leaves while still green: the bulb needs them to flower again next year.

Pruning calendar and basic rules

Propagation

Offsets
Lift a crowded clump in summer once the leaves have died down, separate the bulbs and replant them straight away.
Sowing
Sow ripe seed in autumn in a pot outdoors; seedlings flower after 3–4 years.

Bellevalia paradoxa: how does it get through the winter?

Hardy to −20 °C.

  • Very hardy, to about −20 °C.
  • The bulb needs a cold winter to flower well.
  • No protection needed.
  • In wet, heavy soil the bulbs may rot: make sure of drainage.

Diseases and pests

  • Few flowers: Too much shade, or leaves cut off too early. Give more sun and let the leaves die back.
  • Rotten bulbs: Caused by wet soil in summer or winter. Plant in a better-drained spot.
  • Slugs: May nibble the young leaves; usually limited.

Through the year

  • March: Leaves appear.
  • April: Start of flowering. Bees.
  • May: Flowering ends.
  • June: Leaves die back. Lift and divide crowded clumps.
  • September: Plant bulbs.
  • October: Plant bulbs.
  • November: Last bulbs. Add compost.

Use

Good for wildlife

Bees
Nectar and pollen for honeybees and wild bees.

You and this species

Did you know?

  • The name Bellevalia honours Pierre Richer de Belleval, a French physician and botanist who founded the botanic garden of Montpellier in 1593.
  • Bellevalia and Muscari look alike, but in Bellevalia the flowers are a little more open and bell-shaped rather than globular.
