Plant Description
Pineapple weed is a low-growing erect annual plant that normally grows less than 15 cm tall but sometimes grows up to 30 ½ cm tall. The root system consists of a branching taproot. Stems are erect to semi-erect, ascending, smooth, and branched. Mature plant tends to be bushy when not subjected to competition. The plant is found growing in cultivated and abandoned fields, yards, gardens, roadsides, footpaths, compacted soils in farmyards, waste areas, open areas, bare disturbed areas and rural or urban waste grounds, railroads, irrigation ditches, stream banks, sandbars, cracks in the pavement, rubbish tips, shores, stony slopes of pastures, barnyards and edges of driveways and sidewalks.
Leaves
Stem leaves are alternate; stalk less, hairless, fern-like, 2-3 cm long and 0.6-1 cm wide. Leaf blades are inverted-lance shaped or oblong. They are deeply cut into lobes that are spaced out along the midrib but not cut to the midrib; the lobes do not form separate leaflets (pinnatifid). The lobes may themselves be divided into lobes (bipinnatifid), which may be again divided into lobes (tripinnatifid). Basal leaves are transient and usually disappear by flowering time. Leaves are odorless when crushed.
Flowers
From the axils of the upper leaves, there develops flower heads on stalks about ½–1½ inches long. The flower head of each stalk is about 1/3 inches across, and consists of numerous greenish yellow disk florets and no ray florets. Each disk floret has 4 tiny lobes at its apex. The base of the flower head has several overlapping green semi-translucent bracts that are lanceolate or ovate with papery upper margins. The top of the flower head is shaped like a dome or blunt cone. At the base of the flower head the part of the stem on which the disk flowers are borne (the receptacle) is smooth, not bristly or chaffy. Both the foliage and flower heads have a pineapple-like odor when they are bruised or crushed. The blooming period occurs in between June to September, sometimes into November.
Fruits
Fertile disk floret is replaced by a 2 mm long, dark brown, oblong achene that is broader at the top than the bottom. The achenes are without awns or tufts of hairs. This plant spreads by reseeding itself.
