[4][5] Dendrosenecio keniodendron or giant groundsel is a species of the genus Dendrosenecio of the large family Asteraceae and is one of the several species of giant groundsels endemic to the high altitudes of the Afrotropics,[6] including Dendrosenecio johnstonii[7] (Senecio battiscombei)[8] occurring on Mount Kilimanjaro, Mount Kenya, and the Aberdare Mountains, Dendrosenecio keniensis occurring the lower alpine zone of Mount Kenya and D. keniodendron occurring in higher and drier sites on Mount Kenya.

D. keniensis grows in wetter sites, and therefore at lower altitudes on average, but their ranges abut and they occasionally hybridise.

[9] These branching patterns suggest that plants seldom reproduce more than 4 times before dying.

[9][11] Communities: In the alpine zone of Mount Kenya, Dendrosenecio keniodendron is the dominant woody species, forming evenly sized and evenly aged dense stands with nearly closed canopies.

[9][10] D. keniodendron is endemic to valley slopes and ridges in the alpine zone of Mount Kenya.
