I like umbellifers and I was casting around for suitable white umbellifers to dance in the auratum lily border. “Ammi majus,” they said, “plant Ammi majus.” I have scattered some ammi seed in that border but now I am hoping they will not germinate.
Mark planted some in his vegetable garden, aka his ‘allotment’. The first year it was charming. It is sometimes known as the bishop’s flower or false Queen Anne’s Lace and, curiously, its natural habitat is the Nile River Valley. Mark was wondering about using it as a green crop. It is a member of the apiaceae family, as are most umbellifers including carrot, parsley and coriander.
Well…. allegedly this ammi is an annual that reaches about 120cm in the UK, maybe up to two metres in NZ. Not in our conditions. Semi-perennial, we would say. Mark’s wildflower patch is swamped by towering ammis up to three metres high already and still growing (it is only spring here). The hollow stems are about 3cm across and brittle with it, so inclined to lean and fall. It is a triffid, intent on smothering everything around it. Mark thinks many of these plants probably germinated last summer to autumn so are maybe 10 months old now. It is clearly not a suitable candidate for allowing to self-seed and naturalise in a wildflower situation. That said, it would work if it was cleared out each autumn and fresh sown in early spring. I just can’t be bothered with giving it that amount of attention where I hoped to use it.
I think I would be safer with the pretty Orlaya grandiflora, carrots and coriander amongst the lilies, grown solely for their dancing flower heads and ethereal nature. The orlaya seeds freely, enthusiastically even, but is easy enough to curtail if necessary.
There is no substitute for trialling plants before unleashing them in a naturalistic situation. I learned this lesson with Calamagrostis ‘Karl Foerster’ and I am eyeing up Salvia uglinosa with similar caution.
