Octomeria grandiflora is a species we not be without. It is native to Brazil and we have seen it flowering in forests around Macae de Cima in Rio State growing amongst moss on the trunks of trees in humid primary forest. It appreciates shade and regular watering although we find it does well both mounted or in pots.
The flowers are about 2cm across which seems rather small for ‘grandiflora’ but for an Octomeria species 2cm is huge! We find the species is almost always in flower but gives its main blooming in the autumn.
