Sparaxis tricolor: complete guide

Overview

Sparaxis tricolor, commonly called three-color harlequin-flower, wandflower, or harlequin-flower, is a stunning bulbous plant from the Cape Provinces of South Africa. This member of the Iridaceae family thrives in temperate to warm conditions and blooms primarily in spring. The flowers are celebrated for their striking three-color pattern featuring yellow, red, and purple.

Appearance & Bloom

This plant grows from bulbs and forms an elegant, finely-branched plant with narrow, grass-like leaves. Flowers appear in late spring (May-June in the Northern Hemisphere). Each flower is uniquely marked with bright yellow at the center, a red or purple outer zone, and often black spots or streaks on the petals. Flowers measure approximately 1.5 to 2 inches across and grow in loose clusters. The star-shaped blooms have six petals.

Ideal Location

Three-color harlequin-flower thrives in full sun, requiring at least 6 hours of direct sunlight daily. A warm, sheltered location is ideal. This plant also grows well in containers. For indoor pots, place on a sunny windowsill. In cold climates, dig and store bulbs after blooming.

Soil

This bulb plant thrives in well-draining, sandy soil. A mixture of peat-based compost with 50 percent sand and some gravel works well. The plant tolerates poor soil better than many other flowering plants. In pots, use cactus soil with added grit.

Watering

Watering is essential during the growing season (fall to spring). Keep soil moist but not waterlogged. After flowers fade, gradually reduce watering and stop as foliage yellows. Bulbs can remain dry over summer.

Pruning

Pruning is minimal. Remove only faded flowers and yellowing foliage. After blooming, you can cut stems when foliage begins to decline.

Maintenance Calendar

August-September: Plant bulbs 2 inches deep. October-May: Growing season with regular watering. May-June: Blooming period. June-July: Reduce watering gradually. July-September: Allow drought stress without watering; optionally dig, dry, and store bulbs.

Winter Hardiness

Three-color harlequin-flower is frost-sensitive below 23 degrees Fahrenheit. In temperate zones, dig bulbs after blooming and store dry indoors over summer. Ensure bulbs are completely dry before storage. Place in a cool, dry storage location. In mild zones, bulbs can remain in the ground.

Companion Plants

Combine three-color harlequin-flower with other spring-blooming bulbs such as Freesia, Crocus, and Narcissus. For containers, create a low-growing layer with succulents or moss-forming flowers for striking contrast.
