Drosera regia cultivation was first attempted prior to the formal description of the species in 1926.
The author, Edith Layard Stephens, reported the successful cultivation of D. regia, noting that such success required "a moist and comparatively cool atmosphere", similar to that of its native environment.

Drosera regia is often described as being a difficult species to cultivate, though modern reports on its cultivation have indicated which conditions have led to success for some.
For optimal growth, D. regia appears to require good soil drainage and sufficient light levels, and prefers cooler temperatures.
Cool nights and warm days have been reported to induce vigorous growth.
Asexual propagation is frequently achieved through small root cuttings instead of leaf cuttings, which tend to rot before roots can form.
Seed germination occurs as early as 10 days to 3 or 4 weeks with fresh seed, faster than many other Drosera species.
Germination is phanerocotylar (non-glandular cotyledons exposed, free from seed coverings), with the first true leaves being alternate in arrangement.

In 2004, William Joseph Clemens registered the only cultivar of this species, D. regia 'Big Easy'.
It is reputed to be more robust than other clones of the species and is also more compact with maximum leaf lengths of 23 cm (9 in).
Under his culture conditions, 'Big Easy' has also never flowered or gone dormant.
Clemens originally obtained his D. regia from a vendor at the International Carnivorous Plant Society conference held in 2000.
After sufficient investigation, he registered the new cultivar in a 2004 issue of the Carnivorous Plant Newsletter, the quarterly publication of the International Carnivorous Plant Society.
