Berger's Air Plant

Tillandsia bergeri, known as Berger's air plant, is an evergreen epiphyte in the bromeliad family that grows in clumping rosettes. It carries blue flowers with white centres and twisted petals, held above pink bracts in summer.

South American Roots

This species is native to a stretch running from Rio Grande do Sul in southern Brazil down into the Buenos Aires region of Argentina. It grows there as an epiphyte, mainly within subtropical habitats. It has since been introduced further afield, including the Canary Islands and Great Britain.

Light, Water, Compost

Grow this air plant in partial shade, whether potted in terrestrial bromeliad compost with the leaf bases sitting at or just below the surface, or mounted on bark or a section of tree. Outdoors it wants coarse, open, leafy soil in partial or dappled shade and a frost-free spot. Water with soft water, generously through summer and only sparingly the rest of the year.

Seed Or Offsets

Propagate from seed, or by removing offsets once they have reached at least a third the size of the parent rosette.

Rosette And Bloom

The plant forms a rosette of greyish-green, narrowly triangular leaves that taper to a point and reach up to 15cm long. In summer it sends up flower spikes of 7 to 12cm bearing blue, white-centred flowers with twisted petals emerging from pink bracts. It stays compact, generally reaching only 0.1 to 0.5 metres in height and spread.

Aphids And Mealybugs

Keep an eye out for aphids and mealybugs, the two pests this plant can be susceptible to. Otherwise it is generally free of disease.

Removing Spent Rosettes

Once a rosette has flowered and died back, simply remove it to tidy the clump.
