In the garden
Fritillaria imperialis 'Rubra Maxima' is a bulbous perennial in the Liliaceae, native to Asia and grown for its tall habit and pronounced scent. It reaches about 1.0 m and flowers from March to May, making it a spring architectural element where height is wanted without tree-scale planting. Plant into a sunny site on loamy or clay soils that are moist but well drained; the cultivar favours full sun. It carries a UK hardiness rating of H5, meaning it is classed as hardy and will survive typical winter conditions across much of the UK (USDA zones 7–9 for those gardening to that system). Avoid sites that remain waterlogged through winter, as bulbs prefer soil that drains while retaining some moisture in spring. Use the plant where a tall accent is needed at the rear of a border or beside paved areas where the scent can be appreciated; its stature suits bold spring schemes and formal beds. Handle the bulbs with gloves and other protective equipment: they are ornamental only and not to be eaten, and for further guidance consult the HTA guide to potentially harmful plants for useful contact numbers.
