L. telekii plants usually consist of a single rosette, which grows for several decades, flowers once, and then dies.

Each flower is subtended by a long hairy bract, and the overall appearance has led to the nickname "Cousin Itt

, Lobelia telekii lives at elevations of 3500–5000 m (11,482.9–16,404.2 ft). It inhabits the drier hill slopes, while its close relative Lobelia keniensis prefers the moister valley bottoms. Hybrids do occur. The hill slopes often have rocky moraines that are home to Mount Kenya rock hyrax, which sometimes eat lobelia leaves and inflorescences
