About the genus
Incarvillea is a genus of about 16 species of flowering plants in the family Bignoniaceae, native to central and eastern Asia, with most of the species growing at high altitudes in the Himalaya and Tibet. The most familiar species is Incarvillea delavayi, a garden plant commonly known as hardy gloxinia or Chinese trumpet flower.

In the garden
Incarvillea olgae sits within the genus Incarvillea and the family Bignoniaceae and is recorded to flower in the UK from June to August. Flowering timing is a reliable way to confirm the plant in the first seasons after planting. Cultivation requirements differ between species in this genus, so obtain species-specific guidance from the nursery or seed source for soil, aspect and frost tolerance before committing to a final position. If practical, bring a sample into cultivation first—potted trials through a season reveal moisture and light preferences without risking a permanent border planting. Siting should follow the supplier’s advice; place the plant where its June–August flowering will be visible from a path or patio so you can assess seasonal performance and plan complementary planting. If you need to delay a full planting decision, move mature plants between sheltered and more exposed microclimates to see which suits them best during the flowering months.
