Dense communities of these plants occur in the wild, to the extent that their density can make them virtually impenetrable. Such communities can be very large, and may stretch across several kilometres in their natural habitat. A natural thinning of these stands occurs over time, leaving fewer and larger specimens. They flower mainly in the months of August, September and October, but may begin as early as July and last until December. The large colourful inflorescences are a magnificent sight when the stands are large and dense. "Protea eximia" is one of the easiest proteas to cultivate, and can be grown over a wide range of habitats. From seed, it will sprout within 3 weeks of planting and grows rapidly. It may begin to flower in the second year, but more generally from the third year. It may attain a height of ca. 1.5m within eight years, and is best planted in small close stands so that the plants can support one another. The leaves are susceptible to leaf miners.
