A genus of 45 species of plants. In spite of their common name not all meconopsis are blue; some are yellow and red. However, the blue forms are really stunning and although they can be difficult to grow they are worth the attempt. The flowers of all the meconopsis have the same paper-tissue qualities that those of poppies have.
The plants vary in height from those close to the ground to 1.2m (4ft). Some are annuals others are monocarpic, that is they die once they have flowered and set seed, which may be several years after they germinate. Most meconopsis need a moist soil and a moist atmosphere and so they do better in a damp maritime climate than in drier inland areas. In drier areas it is important to grow them in a position where air is moist or the plants will not really succeed. They need a rich, moisture-retentive soil, although the soil should not be too wet in the winter. They prefer a partially shaded site away from the hot sun. They are best grown in a woodland situation, possibly planted next to a stream or waterfall.
