Sinningia tubiflora
Beautifully drooping, long tubed, white trumpets held high on long slim stems emit a wonderfully sweet lemony fragrance in late summer. Makes a mound of softly hairy grey-green foliage. Give this Gesneriad full sun. Happy outside so far with me and others in the Cotswolds on well drained soil. Bulks up splendidly by way of tubers. Quite gorgeous.
