Jesus also commits another scientific blunder when he declares the mustard seed to be the smallest seed of the earth (Mark 4:31). There are, in fact, many seeds smaller than the mustard, such as the South American orchid.
But;
The very idea of Parables implies, not strict scientific accuracy, but popular pictorialness. It is characteristic of them to present vivid sketches that appeal to the popular mind and exhibit such analogies of higher truths as can be readily perceived by all. Those addressed were not to weigh every detail, either logically or scientifically, but at once to recognize the aptness of the illustration as presented to the popular mind. Thus, as regards the first of these two Parables, the seed of the mustard plant passed in popular parlance as the smallest of seeds. In fact, the expression, ‘small as a mustard-seed,’ had become proverbial, and was used, not only by our Lord, but frequently by the Rabbis, to indicate the smallest amount, such as the least drop of blood, the least defilement, or the smallest remnant of sun-glow in the sky. ‘But when it is grown, it is greater than the garden herbs.’ Indeed, it looks no longer like a large garden-herb or shrub, but ‘becomes,’ or rather, appears like, ‘a tree’—as St. Luke puts it, ‘a great tree,’ of course, not in comparison with other trees, but with garden-shrubs. Such growth of the mustard seed was also a fact well known at the time, and, indeed, still observed in the East. (

The main point of the parable is that under such small beginnings the kingdom of God in Christ will expand disproportionately to its original 'small' size. History has borne the truthfulness of the parable out quite evidentially.
