UK gardener here. Just to reiterate. This plant is an annual which only grows from seed. Anything spreading by root, or repeat flowering of the same plant is NOT Ammi Majus.

In ideal conditions it MAY be a quite prolific self seeder, but pull up the seedlings where they are not wanted - we all have to maintain our gardens for goodness sake. Continual deadheading will inhibit self seeding. Collect the seed and sow where you want it next year.

It's big advantage is that ( in the UK at least) it attracts a wide range of pollinators,particularly hoverflies, which with the reduction of bees these days is a good thing.

Amen pb1234. The mixed use of "ammi" and "daucus" for two different plants is annoying and rife. It is also disrespectful to these plants that are so beautiful and interesting in unique ways. For starters, Daucus has a tiny red dot in the center for which it earned it's common name "queen annes lace," ammi does not. They each have their own cultivars and the latin names should be observed in order to understand their different behavior, requirements, and genetics. I find that even seed companies mix the names up in their branding.

Love this plant. A favorite. Grow from seed by sowing in the fall. Romantic. An excellent cut flower. This is not the roadside invasive Queen's Ann's lace.It is infuriating to see how many people need to be educated about latin botanical names. Read the name with the genus and species: Ammi majus. I am constantly and continuously having to correct people who are completely incorrect and are so wrong in making false assumptions about this plant, acting as so assured about it when they are completely ignorant. Just because something may look similar does not mean its the same! This a lovely plant with enchanting flowers that is not invasive.

3-4 weeks of flower in june,....not really worth it.
Plants also brown rapidly in july and august then look bad if planted en masse or even planted singly with nothing in front of them.
Therefore best used as single filler plants between other tall plants.

Ammi Majus, False Queen Anne's Lace, is lovely. I am familiar with aegopodium, Bishop's Weed, and this is NOT the same thing. I planted a few seedlings last year and was sad that the plants were so short lived. This year, much to my delight, volunteers came up in the most serendipitous spots regularly throughout the season. They were easy to remove where not wanted, but added greatly to the overall picture all summer.

NOT invasive. Educate yourselves people. This is an annual....not the invasive perennial !! Note the difference. You are mistaken. Learn the details. Names matter.

No one on the site mentioned fragrance. I have a plant in my yard that is quite similar to this, tall, reseeds freely, but is definitely fragrant - people either love or hate the fragrance. Any idea what the name might be?

This plant came up in a pot in my San Diego backyard. It may have come from a bunch of seeds I brought home and scattered around. The first year it didn't bloom, but it came back the next year with a glorious bloom. I went out and took pictures with my digital camera and put them into my computer file.

The next day I went outside to garden, and the plant was completely gone. It had been pulleld from the pot, roots and all. I even went back in and checked the computer in case I was imagining the whole thing.

The man next door had some workers in his yard the day before and I guess someone jumped the six foot fence. The next year, a couple leaves came up, but nothing since. So I really must get some seeds of this to grow and see if it is indeed the s... read more

I ordered seed and direct sowed it not knowing what to expect. I have been pleased with the results and plan to use the plant more deliberately next year. Elegant in its simplicity, and more tidy and delicate in appearance than the fuzzier Queen Anne's Lace, in sunny, dry conditions it has stayed erect in conditions that have caused nearly everything else to wilt. I plant to use it among daisies and coneflower next season.

Ammi majus, White Bishop's Lace, is as beautiful and graceful as promised. Sown in late May from Renee's Garden seed, my plants are still small and delicate in nature, growing best in full sun. A must for the romantic garden. I've seen this effectively interplanted in garden beds that allows the flower heads to be held above and contrasted with larger, darker foliage, while concealing the relatively skimpy foliage.

Unlike Louannie, I am personally pretty sure that most people with negative comments are going solely by the common name Bishop's Weed and assuming that this is the incredibly thuggish Aegopodium podagraria (the cultivar 'Variegatum' is particularly virulent), which is the plant usually referred to as Bishop's Weed, without actually checking the botanical name (or even the photos!). [I've found this sort of thing to be a common mistake on Dave's Garden when there is a relatively uncommon plant that is listed as having one of the same common names as a much more common plant. I'm not sure what can be done about it except maybe placing a notice at the top of the page not to confuse the lesser-known plant with the other one.]

Regardless, this is a lovely plant that is wonderf... read more

I bought some seed of this plant because it is purported to be a non-invasive and useful alternative to Queen Anne's Lace. I have not yet planted the seed and have no growing experience with it. After buying the seed I researched and see that some sources say it is "non-invasive" but others say it can naturalize. One site provided me with some alarming info. "Bishop’s-weed contains a furocoumarin in all parts of the plant, but it is especially concentrated in the seed. The compound is photoactive, causing primary photosensitization in cattle, sheep and birds. All animals consuming the seed should be considered at risk." If you are considering planting you should read the entire site entry because the toxicity effects can be a serious. As for me, I live in the country near grazing livestock... read more

I have experienced an invasion by Queen Anne's Lace, but I have to say that my experience was not as fraught as others...I saw one posting that said to dead head...and they are absolutely right. The bloom period for QAL can be extended by deadheading...but the umbells tend to become smaller with each incarnation... They are beautiful plants, I also have Bishop's Weed... I like it too, and all I have to do to control it is rip it out...and keep ripping it out!!!lol. I use it as a ground cover/foundation planting around the north side of my house... when it sends up its flower stems I pick them off. if all else fails run a lawn mower or weed eater over it... Of all the plants in my front garden the QAL drew the most comment. If cut flowers are what you want...they will be just fine if ... read more

I'm not sure some of the notes here are accurate. Here is what I found on a site called about Ammi majus:

This is the "other" Queen Anne's Lace. The more common one, Daucus carota, the roadside weed in all 50 states, is considered an invasive pest in many areas, so probably should not be planted, although you may end up with it naturally in your meadow. This species (Ammi majus) is also called Bishop's Flower, and is an annual, while the more common one is biennial. This species (Ammi majus) is not invasive, but it can be toxic to animals, so keep that in mind. Very easy to grow, and great for cutting.

Some of the people here may be growing Daucus carota instead of Ammi majus. I'm no expert for sure, but that's what it soun... read more

When I was about 8 my mother was quite taken with this plant in a neighbor's garden and thrilled to death to be offered some of the "lovely groundcover".

By the time I was a teenager she was regularly cursing it. She'd planted it at one end of the flowerbed and it ate the entire space, impossible to slow down or get rid of, smothering everything else she tried to plant there.

I work at a retail nursery and frequently hear customers comment on how hard and confusing latin names are. However, common names can be even more so, especially when they are used for many different flowers!

Aegopodium podograria is the latin name for the Bishop's Weed that certainly is an aggressive groundcover, even noxious when it is where you don't want it. Many years ago, I inadvertantly brought some back with other plants from my mom and still pull a sprig or two each year.

Ammi majus is the latin name for Bishop's Lace, Bishop's Weed, or False Queen Anne's Lace. It is used in many floral arrangements. This will be my first year growing it and I hope it will add some airy white to the garden. While it is suppose to reseed, deadheading should hel... read more

I haven't had problems with this seeding everywhere, but I cut it back before it could. The flowers are very pretty, but I can see how it could easily get out of hand.

I have read that it grows in zones 3-9 (annual). Light aids germination of seeds.

This plant will take over your garden if it is not contained. It spreads by both seed and side roots. A small patch of it was in our garden when we moved into our home 10 yrs ago and it has now taken over every perrenial bed in our entire 1 acre lot. I would avoid this species like the plague. Once it's in your garden it is impossible to get rid of. We've tried everything. Even poured gasoline over it and set it on fire. I suppose in the right setting it might be good, say on a hilly slope to stop soil erosion, but once again, you'd have to dead head all those white queen anne's lace type flowers before they set seed or next year you'll find it in other beds and it's really tough to pull out.
