More Details

Ammi majus (Bishop's flower) has lacy, white flowers, like a more delicate form of cow parsley. This one is one of our long-standing best sellers.

Ammi majus is the best white filler-foliage plant you can grow and spectacular arranged in a great cloud on its own. It forms larger, more prolific plants from an autumn sowing.

Please note: This may cause skin irritation in some cases so we recommend you wear gloves.

I grew a large number of plants from an Autumn sowing and the plants were robust and thankfully not fussy re treatment. The majority did flop over however, taking other things with them as they are on the large side. Also, although beautiful on own in vases and mixed arrangements they do start to drop pollen quite prolifically after day 2.

Fabulous ammi

Bought five plants for the first time this year - they are amazing! Will have a go at raising them from seed this autumn ready for next year. A great addition both to the garden and for flower arranging. Are inclined to fall over as my garden tends to be a bit windy so will make more effort to support them too!

An update: an autumn sowing of these, kept in my cold frame through the worst of the winter and planted out in early spring has produced plants which are now well over 6ft tall !!

I'd never come across this flower before, so growing it from seed was a first for me, but I loved it - so dainty and pretty. Very easy to raise from seed. It had a slight tendency to be spindly and (in my sandy soil) fall over, but I've taken Sarah's tip to sow now (late autumn)for sturdier plants next year, and will plant out where it will grow up between, and be supported by, stronger growers. My new 'must have' flower!

Lovely show

Still going - it's October now and these have come out in early July in our border. They are intermingled with the wonderful verbena bonariensis and they make a fab pair. Very happy.

Ammi, my forever favourite

Due to moving house (and garden), I could only sow these seeds at their current position at the end of April. They started to flower late June and they never stopped since. The plants are healthy and tall and just beautiful.
