Porophyllum linaria is an erect to decumbent annual to perennial plant, usually branching from near the base, growing 10 - 50cm tall[

N. America - central and southern Mexico
Porophyllum linaria is a plant of semi-arid, subtropical to tropical climates. It is not tolerant of frost, but can generally be cultivated from the warm temperate zone( with hot summers) to tropical areas.
Requires a sunny position, succeeding in a range of soil types so long as they are well-drained.
A fast-growing plant, it can reach a height of 60cm within 30 - 45 days and can be harvested on a cut and come again basis until cut back by cold weather.
The aromatic oils, which are contained largely in the pores or glands that are especially plentiful on the leaves, produce a strong odour when the foliage is bruised, broken, or heated. Cures, real or fancied, that are attributed to various species of Porophyllum are probably largely due to either the soothing properties of the oils or the imagination by the patient that anything that is so odoriferous must be beneficial[
Leaves - cooked and eaten as a vegetable[
]. Used especially as a flavouring.
Seed - sow in containers in a greenhouse in the spring. Plant out after the last expected frosts and give protection on cold nights.
