Legousia hybrida

Venus' looking glass is native to bright, open habitats and performs best in full sun. It will tolerate some partial shade, but favors direct sunlight for the best growth. This plant, which may be annual or biennial, is noted for its sun-loving habit.

Venus' looking glass can tolerate a wide range of temperatures, but its distribution may still be constrained by various combinations of moisture and heat. It performs best in warm summer climates with sufficient rainfall or watering. Extended periods of cloudy, rainy weather, as well as prolonged high temperatures, can increase the chance of Venus' looking glass dying. In winter, protecting it from cold can raise the plant's survival rate.

When Venus' looking glass has opened most of its blooms to full size, resume fertilizing. At the period of peak bloom production, fertilize every three to four weeks, weather permitting. Then, once Venus' looking glass begins producing fewer new blooms, stop fertilizing; there is no need to feed the plant when it can no longer produce more blooms.
