India GOFlowers and trees of Ooty and Coonoor
The flowers Ooty is famous for grow in gardens: more than 3,000 varieties in the Government Rose Garden and the Botanical Garden, where the flower show is held every May. The hills' own plant life is quieter: shola forest in the folds, grassland on the ridges, and blooms that come in their own seasons. Much of the deep green seen from the toy train is eucalyptus plantation, and it is worth knowing which is which.
Nilgiri rhododendron
It is the only shola tree that survives grassland fire, which is why old individuals stand alone on burnt slopes. Recent phenology work reports its flowering advancing by three to four weeks at higher elevations.
Rhododendron arboreum subsp. nilagiricum
Tasmanian blue gum
Blue gum lines the Nilgiri Mountain Railway and covers whole Nilgiri hillsides. Eucalyptus and black wattle are named as the major invasive species of the Nilgiris and have replaced large stretches of native shola and grassland. The railway view that looks like deep forest is largely a plantation, and it is worth knowing which is which.
Eucalyptus globulus
Tree fern
Sim's Park, opened in 1874 on about 12 hectares at roughly 1,780 m, keeps a natural shola remnant inside a laid-out garden, which is why tree ferns, camellias and magnolias stand there together. The Government Botanical Garden at Ooty, established in 1848, holds a fossilised tree trunk about 20 million years old.
Cyathea spp.
Scotch broom
Its local Tamil name refers to Kotagiri, where it is most conspicuous. Wherever it establishes it has wiped out the indigenous grasses, which hits the Nilgiri pipit and other ground-nesting birds directly. It was brought to the Nilgiris and has since taken over open downs, one of the worst things to happen to their grassland.
Cytisus scoparius
Osbeckia (Indian rhododendron family)
It is one of the plants that shows why the Nilgiri grassland is not empty ground waiting to be planted: the open downs carry their own flora, and it flowers when the wattle blocks are just dark green.
Osbeckia spp.
Where to see flowers in Ooty and Coonoor
- Government Rose Garden: five terraces on the slope of Elk Hill, about 4 hectares, laid out to mark the centenary of the flower show. More than 3,000 varieties grow here: hybrid teas, miniatures, floribundas, ramblers and roses in unusual colours, black and green among them. Rose tunnels and pergolas run along the terraces, and the Nila Maadam viewpoint takes in the whole garden. Flowering peaks from April to June.
- Government Botanical Garden: laid out in 1848 on terraces below Doddabetta, about 22 hectares, kept by the Tamil Nadu Horticulture Department. Look for the fern house of ferns and orchids, the Italian-style garden by a pool, and the trees: a cork tree, a paper bark tree and the monkey puzzle tree, which monkeys cannot climb. Its oddest exhibit is a fossilised tree trunk about 20 million years old.
- Sim's Park, Coonoor: opened in 1874 in a deep ravine north of Coonoor station, about 12 hectares at 1,768–1,798 m. It keeps a patch of natural shola inside the laid-out garden, which is why tree ferns, camellias and magnolias stand together, and it grows rudraksha, the bead tree. It is also the venue for the fruit show in May.

The Ooty flower show
The flower show fills the Botanical Garden every May, with an exhibition of rare plants alongside. It was first held in 1896, and in the same weeks the Horticulture Department runs the vegetable show at Kotagiri and the fruit show at Sim's Park in Coonoor. The district announces the exact dates each spring. Tickets are sold at the gate, but beds in Ooty and Coonoor are booked out weeks ahead for show week, rooms cost double or triple, and the district sets up traffic diversions and remote parking: arrive the day before. More on the season: best time to visit.
The hills' own plants: shola and grassland
Shola is the montane evergreen forest that survives in the folds and hollows of the Nilgiri plateau, with rolling grassland on the ridges between. Both have their own flora, and the open downs are not empty ground waiting to be planted.
- Nilgiri rhododendron (Rhododendron arboreum subsp. nilagiricum): the only shola tree that survives grassland fire, which is why old trees stand alone on burnt slopes. It flowers from January to March, and studies report the flowering moving three to four weeks earlier at higher elevations.
- Osbeckia: a grassland plant that flowers from September to December, after the monsoon, when the wattle plantations are just dark green.
- Tree ferns (Cyathea): best seen in the shola remnant at Sim's Park, green all year and freshest after the monsoon.
- Kurinji (Strobilanthes kunthiana, Neelakurinji): a shrub of the Western Ghats sholas whose purplish-blue flowers come out only once in twelve years, in September and October. The name Nilgiri, "blue mountains", is traditionally linked to it. Different populations keep their own twelve-year cycles, and plantations now cover much of its old habitat, so a mass bloom is an event rather than a season.
Plantation or forest: what the slopes really are
Tasmanian blue gum lines the Nilgiri Mountain Railway and covers whole hillsides; eucalyptus and black wattle are named as the major invasive species of the Nilgiris and have replaced large stretches of shola and grassland. The view from the train that looks like deep forest is largely plantation. Scotch broom, brought to the hills and flowering mainly from December to April, has taken over open downs: its Tamil name refers to Kotagiri, where it is most conspicuous, and where it spreads the native grasses disappear, which hits the Nilgiri pipit and other ground-nesting birds. That is why grassland such as Wenlock Downs matters as grassland. More on the wildlife that depends on it: birds and animals.
