Crocus vernus aka Spring Crocus

Taxonomy

Crocus vernus, also known as spring crocus or giant crocus, is a species in the Family Iridaceae. It is native to the Alps, the Pyrenees, and the Balkans. This species, along with its cultivars and those of Crocus flavus, are commonly used as ornamental plants. The Dutch crocuses, which belong to this species, are larger compared to other cultivated crocus species such as Crocus chrysanthus. Crocus vernus is an early spring blooming bulb, specifically a corm, that is primarily found in high alpine areas in Europe. It is often referred to as Dutch crocus, large flowering crocus, giant crocus, or spring crocus. Its beautiful goblet-shaped flowers come in shades of purple or white. The foliage is narrow, starting upright and then spreading. Flowering typically begins in late March and lasts for about three weeks. The flowers close at night and open in the morning, although they usually remain closed on rainy or cloudy days. The plant's basal leaves resemble grass and turn yellow as the plant goes dormant several weeks after blooming. The genus name Crocus is derived from "krokos," the ancient Greek name for saffron. This plant has a long history and is considered one of the most ancient plant names. Crocus vernus is a versatile and popular choice for naturalizing in grass, adding vibrant colors to the landscape during the early spring season.

How to care for Spring Crocus

Difficulty

Spring Crocus requires a bit more attention and knowledge to thrive, making it a suitable plant for those with some gardening experience.

Water

Spring Crocus should be watered regularly, allowing the soil to dry out between waterings.

Soil

Spring Crocus loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Spring Crocus requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Spring Crocus will be sure to bring you many years of beauty and enjoyment.

Dormancy

During the cold period, it is common for Spring Crocus to go dormant and their growth may slow down, so waterings should be spaced out more during this period.

Toxicity

Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.

Fertilizer

The Spring Crocus should be repotted either when it doubles in size or annually, whichever comes first. Providing new potting soil with all the vital nutrients annually is enough to support the growth of the plant, and thus, there is no need for fertilizer. Remember that plants derive their energy from the sun, not fertilizer.
