Buy Ammi majus bishop's weed: A billowing, non-invasive cow parsley

  • Position: full sun or partial shade
  • Soil: any moist but well-drained soil
  • Rate of growth: average
  • Flowering period: June to September
  • Hardiness: hardy annual

    Dainty white summer flower-heads, which look like fine lacework, hover in a frothy haze above the finely cut, green foliage. Often used by florists to add an ethereal, romantic feel to bouquets, the flowers are also loved by many beneficial insects including butterflies and hoverflies. Finches will also find the autumn seed heads attractive. This annual also looks a delight in the garden, and has quite an architectural feel. Stake plants as they start to shoot upwards with twiggy hazel stems for support.

  • Garden care:Fill trays with good quality compost and lightly cover the seeds. Water, and place in a cold frame or greenhouse. Pot on when they have put on their first true leaves and then harden off before planting out after the frosts have passed. Alternatively sow direct in late spring or early summer and thin out to 20-30cm as they grow. Seeds sown in autumn and overwintered in a cold frame, will produce bigger plants which will flower earlier in the year than those sown in spring.

  • Sow: September-November or March-May

  • Flowering: June-September

  • Approximate quantity: 500 seeds.

Wonderful Value


These seeds produced many tall plants which lasted throughout the summer. The seed heads were attractive so some plants were left and those that were cut back flowered again on shorter stemms. Excellent dotted about in mixed borders.

Hi, Is ammi majus toxic in any way? I thought I read somewhere it could cause skin irritation, but also that it is used in bouquets of flowers, which would suggest it is fine to touch. I have a child with sensitive skin so keen to get to the bottom of this. Many thanks!


Hello, I have double checked my RHS encyclopedia and the HTA guidance notes relating to poisonous plants and I cannot see any reference to this being poisonous in any way.


Ammi majus - common name I bought some Ammi majus plants from you and they were succesful BUT you also call them Queen Anne's lace - are you sure this correct ? Checking this out, the name Queen Annes lace seems to be more correctly applied to cow parsley, or (in the US) the wild carrot, which are perennials - and so the name may be misleading to some even though you indicate it is an annaul regards John


Hello John, Many years ago when I was a student, we were forbidden from using common names because they tend not to be very specific and they can be very misleading. The common names for Ammi majus include white lace flower, false Queen Anne's lace and bishop's weed, and I'm sure all of these common names could also be attributed to a number of other plants too. I have however changed the common name on our site to Bishop's weed and I hope this will prevent further confusion.

There is still plenty of time to raise hardier annuals from seeds sown now and these include cosmos, zinnias and marigolds. However it's often easier to opt for ready-grown plugs of these, as well as the more-tender begonias petunias, antirrhinums and ni
