Brugmansia ‘Charles Grimaldi’

Possibly the most popular of the modern hybrids, ‘Charles Grimaldi’ produces large, opulent fragrant blooms reliably in bursts throughout the late summer and into autumn.

It is properly called Brugmansia x cubensis ‘Charles Grimaldi’ as it is the creation of an x candida hybrid (from B. aurea and B. versicolor) itself hybridised with a B. suaveolens. Probably because of this genetic soup, 'Charles Grimaldi' is especially vulnerable to Datura mosaic virus which, while incurable, is mostly benign causing a mottled pattern on the foliage especially in low temeratures. 

Alternatively pick one up at a plant show or fair where they will be available in various sizes.
