Saffron crocus Crocus cartwrightianus
ABOUT
Crocus cartwrightianus, commonly known as the wild saffron crocus, presents itself with a beautiful and delicate appearance, typical of the crocus family. The plant blooms with striking flowers that are often admired for their ornamental value. The blooms are characterized by their radiant and typically purple petals, which sometimes can also be white or light mauve in color. At the center of each flower, the bright orange stigmas stand out prominently, providing a vivid contrast to the petals. These stigmas are notably significant as they are harvested to produce saffron. The flowers resemble a cup-like shape, cradling the reproductive organs within. Surrounding the stigmas, one can notice the lighter colored anthers, which add to the visual interest of the flower. The petals are slender and elongate, coming to a gentle taper at the tips, and they can often showcase delicate veining or color gradients that add depth to their appearance. The plant's foliage consists of slender, grass-like leaves that are green and sometimes have a stripe pattern. These leaves typically emerge either before or along with the flowers, creating a soft backdrop that accentuates the blooms. As the seasons change, the wild saffron crocus goes through a lifecycle that includes a period of dormancy, where the above-ground parts of the plant die back, leaving the corms (a type of bulb) underground until the next growing season.

WaterSaffron crocus (Crocus cartwrightianus) should be watered sparingly, as overwatering can lead to bulb rot. During the growing season, in fall, water them when the top inch of soil feels dry, typically once a week, with approximately a quarter gallon of water per plant. After blooming and once the leaves start to yellow, gradually reduce watering as the plant enters dormancy. During dormancy in summer, watering should be very minimal or not at all, keeping the soil mostly dry.
LightSaffron crocus thrives in full sun to partial shade. To ensure healthy growth, plant them in a spot where they receive at least six hours of direct sunlight per day. They can also tolerate light dappled shade, but flowering might be less prolific without full sun exposure.
TemperatureSaffron crocus prefers a temperate climate with chilly winters and hot summers. They can survive winter temperatures down to about 15°F, but ideally, they should not be exposed to prolonged periods below 20°F. The ideal temperature range for growing saffron crocus is between 35°F and 85°F, mimicking their natural Mediterranean climate.
PruningSaffron crocus does not require regular pruning. The only necessary pruning involves removing spent flowers and yellowing foliage after blooming is complete, which usually occurs in late fall. This helps prevent diseases and tidies up the plant. Dead foliage should be cut back to the ground once it has completely died down.
CleaningNot needed
SoilSaffron crocus requires well-draining soil with a pH range of 6.0 to 8.0. The best soil mix can be made of equal parts sand, loamy garden soil, and compost to ensure proper drainage and fertility.
RepottingSaffron crocus bulbs should be lifted and divided every 3 to 5 years to maintain vigor and to prevent overcrowding.
Humidity & MistingSaffron crocus thrives best in dry conditions and does not require high humidity levels.
Suitable locationsIndoor
Place in bright light, well-draining soil, cool temperature.
Outdoor
Plant in well-drained soil, full sun to partial shade.

Life cycleCrocus cartwrightianus, commonly known as wild saffron crocus, begins its life cycle as a bulb, which remains dormant underground during the hot and dry summer months. In the fall, when the temperature cools and moisture levels increase, the bulb awakens and sprouts thin, grass-like leaves and a flowering stalk. The flowers are generally white to pale purple with purple veins, blooming from late fall to early winter. Following pollination, usually by insects, the plant sets seed, which falls to the ground and can grow into new bulbs over time. After flowering, the leaves continue to photosynthesize and store energy in the bulb until late spring when the plant enters dormancy again as temperatures rise. The life cycle continues as the bulb remains dormant through another summer, preparing to emerge again in the fall.
PropogationPropogation time
Autumn
Propogation: Crocus cartwrightianus, commonly known as the wild Crocus or Saffron Crocus, is typically propagated through its corms. The best time to propagate this plant is in late summer after the corms have gone dormant following their spring flowering cycle. To propagate, carefully unearth the corms and select the largest and healthiest ones for replanting. These corms should be planted around 3 to 4 inches deep (about 7.5 to 10 centimeters) and spaced approximately 3 inches apart (approximately 7.5 centimeters) in well-draining soil that receives full to partial sunlight. Water the newly planted corms moderately to establish them. Over time, these corms will produce offsets that can be separated and planted to propagate new plants.
