Moraea hiemalis is not well known in cultivation. It is a summer-growing species and thus can be treated similarly to Moraea spathulata although it is deciduous where Moraea spathulata is evergreen and it thus needs to be kept dry in winter. Sow seeds in spring or early summer. Grow plants in well-drained, humus-rich, acidic soil in a sunny position, with water in spring and summer and a dry winter. They are suitable to be grown in containers.

In general, moraeas are easily grown from seeds, and are best cultivated in a light, well-drained medium and enjoy full sun once fully matured. Sow seeds directly in a well-drained mix, when the plants will experience temperature variations of warm days and cool nights. The winter-growing species are best propagated in autumn, and summer-growing species in are best in spring. According to Dell Sherk of the Pacific Bulb Society, germination could happen within three weeks or may take as long as three years, depending on the species. Most species will require three years to go from seed to flower, but Mary Sue Ittner, of the Pacific Bulb Society has observed Moraea polystachya and Moraea villosa to flower in 1-2 years. Will Ashburner, of the Pacific Bulb Society, recorded germination and flowering time of 12 species as follows: (the first number is weeks to germination and the second is weeks to flowering) Moraea alticola (10, 118), Moraea bellendenii (5, 130), Moraea bubalina (5, 136), Moraea insolens (5, 129), Moraea macronyx (5, 120), Moraea moggii (29, 136), Moraea ramosissima (6, 130), Moraea serpentina (3, 130), Moraea spathulata (6, 135), Moraea thomsonii (6, 128), Moraea tricuspidata (5, 126), Moraea tripetala (3, 121-124).
