Buy Trillium grandiflorum American wake-robin bulbs: An award winning pure white form

  • Position: deep or partial shade
  • Soil: humus-rich, moist, well-drained soil
  • Rate of growth: average
  • Flowering period: April
  • Hardiness: fully hardy

    This trillium has been given the Award of Garden Merit by the Royal Horticultural Society for its top performance in the garden. The luminous white flowers that often fade to pink are perfect for brightening up a shady, moist bed or woodland garden in mid to late spring. The large, broad-petalled flowers are a knockout.

    These plants are quite hard to grow and will take some time to establish large clumps, so they are better suited to the more experienced gardener.

  • Garden care: Plant rhizomes 5cm deep and 5cm apart in autumn. Once planted they are best left undisturbed so they can build up their numbers. Mulch in the autumn with a generous layer of leafmould.

  • CAUTION do not eat ornamental bulbs

Notes on Trillium grandiflorum

"Large, wavy-edged white flowers held on dark stems above dark leaves and strong enough to carpet the ground in friable conditions under a woody canopy."

Exacting conditions


Suspect planting depth is important. Bought pack of 3. Saw two first year. One produced a lovely flower the second year. Would recommend with reservations.

Worth the effort.


I tried to simulate the natural habit (cool and damp), resulting in 2 out of 3 successfull bulbs.

Trillium care Hello, Thank you for my Trillium bulbs which arrived this morning, even though there is a strike! Can you give me any help with teh care of them only I 've never been very successful so far with growing them. I plant them and they just disappear never to be seen again! So any help you can give would be appreciated. Jean

Hello Jean Any general purpose fertiliser will do - just use half the amount they recommend on the box Best regards, Helen Plant Doctor

Hello Jean, These plants like a partially shaded spot with ordinary soils that have a near-neutral pH. They like lots of leaf litter, but you should avoid using peat if possible as it holds too much water. Plant the rhizomes 5cm deep and 5cm apart and feed them with a half-strength dose of general purpose fertiliser before the leaves appear. Nearly all of them can cope with summer drought, but they can be damaged by late frosts. Once planted they are best left undisturbed so they can build up their numbers. Mulch in the autumn with a generous layer of leaf mould. I hope this helps. Helen Plant Doctor
