In the garden

Gladiolus tristis 'Christabel' is a bulbous perennial native to South Africa, grown for its fragrant summer flowers. In the UK it reliably flowers from July to September, producing pale, scented blooms best enjoyed close to paths or windows where the perfume can be noticed. Give it a south-facing, sheltered site with full sun or light afternoon shade. It prefers well-drained sandy or loamy soils of neutral to slightly acidic reaction and does not like waterlogged conditions; a freely draining mix in containers will prevent corm rot. Soil moisture should be moderate rather than persistently wet, and an open, protected spot reduces wind damage to the flower spikes. Rated H4 (average hardiness) in the UK, plant in a place where winter wet is avoided and where you can lift or protect corms if your garden is especially cold and wet. Use in mixed summer borders, in large pots on a sunny patio, or cut as single stems for seasonal bouquets. The fragrant spikes perform especially well as cut flowers, bringing their scent indoors during late summer.
