Spotlight on Tillandsia heteromorpha

Tillandsia heteromorpha is an epiphytic bromeliad that forms a stem on which linear, curved, very slender leaves develop, covered in dense but very short down. It is found exclusively in Peru, mainly growing on rocks (saxicolous), at altitudes of between 800 and 900 metres. Over the years, the rosette of leaves develops in a remarkably symmetrical pattern. If the plant has already flowered, the rosettes multiply, creating a superb spectacle. Flowering, however, is something to be earned! The flower spikes display a colour gradient ranging from green to pink, from which purple and white flowers emerge.

The Latin name *heteromorpha* means ‘having different forms’. Given the highly symmetrical appearance of the rosette, this seems surprising. In fact, the variations lie between individual plants: the leaves vary in length, and the stems exhibit widely varying degrees of twisting. Ultimately, the plants all look very different from one another.

Another distinctive feature: after several years, large numbers of rosettes may develop directly on the thick main stem!

Although not widely grown, this species is nevertheless splendid (it becomes increasingly impressive with age) and fairly hardy. It can be hung outdoors in spring and summer. It thrives in relatively dry conditions and enjoys exposure to the wind…
