Abstract: This new and distinct cultivar of Alstroemeria named `Sweet Laura` is characterized by its unique features of sweet fragrance, yellow flower color, vigorous growth, cold tolerance, and strong, upright floral stems. It is the first commercial Alstroemeria plant with fragrant flowers. The three outer tepals of the flowers are yellow with an orangish-red color at the tips that often emanates throughout the length of the tepals; the extreme tips of these tepals are green. The three inner tepals are also yellow, but their orangish-red region is absent or restricted to the extreme tip. The inner tepals also have narrow, longitudinal light brown streaks that radiate from the base to the tip. The streaking occurs with less frequency on the lower tepal. The plant is also distinguished by its long (80 to 85 cm), strong flowering stems with narrow long-lasting dark green leaves and its upright and vigorous growth habit.
