Cultivars
The following cultivars represent praestans in cultivation:
T. praestansFuselier;[11] grows up to 30 cm tall, with grey-green, lance-shaped leaves and stems in mid spring,[12] bearing between three and five,[4] cup-shaped, brilliant red,[12] or bright red flowers,[13] that can measure to 12 cm across.[12] It has gained the Royal Horticultural Society's Award of Garden Merit.[14] It is valued by gardeners for its low growth height and habit of producing many flowers per bulb. 'Fusilier' even has a sport, 'Unicum'.[15]
T. praestans 'Unicum',[16] with the leaves edged in cream.[15]
T. praestans 'Moondance',[17] - has deep orange flowers which are relatively large and have pointy petals.[10]
