Did You Know?
1. Crocuses are known for being one of the first flowers to bloom in spring, but did you know that they can spread easily by producing tiny cormlets? These small, baby corms grow around the base of the main corm and contribute to the flower’s ability to spread and form beautiful clusters.
2. While many crocuses are native to mountainous or Mediterranean regions, there is one species called the “Crocus sativus” or saffron crocus that is especially unique. Not only does it have beautiful purple petals, but it also produces three bright red stigmas, which are carefully hand-picked and dried to produce the highly sought-after spice, saffron.
3. Have you ever wondered how crocuses can survive harsh winter conditions? These resilient flowers have a fascinating adaptation known as “thermogenesis.” When temperatures drop below freezing, crocuses can generate heat within their flowers, allowing them to bloom and persist even in frosty environments.
4. Here’s an interesting fact about crocus cultivation: before they were widely available for purchase, crocuses were coveted by wealthy garden enthusiasts in the 17th century. To protect their treasured flowers, these gardeners would keep crocus bulbs under lock and key!
5. In mythology, crocuses are associated with the ancient Greek story of Crocus and Smilax. The legend tells of a young love that ends in tragedy, as the gods transformed Crocus into a beautiful purple crocus flower and Smilax into a delicate bindweed plant. This story serves as a reminder of the fleeting nature of love and the beauty found within the crocus bloom.
Crocus Varieties and Availability
Crocus tommasinianus, also known as Tommasini crocus, is no longer grown commercially. However, there are several other varieties of crocus that are available, including heirloom varieties such as C. tommasinianus Roseus (1925), C. flavus Golden Yellow (1665), C. vernus Flower Record (1958), C. vernus Jeanne d’Arc (1943), and C. vernus Vanguard (1934). These heirloom varieties have been cherished for their unique characteristics and long history.
Planting and Care Tips for Crocus Bulbs
When planting and caring for crocus bulbs, there are several important factors to consider:
-
Bulb Type: Crocus bulbs are corms with either a smooth (annulate) or fibrous (reticulate or netted) tunic. Check the shipment of bulbs against the packing slip to ensure they are in good condition. Some bulbs may have cuts, scars, or discoloration, which are normal marks from harvesting, cleaning, and sizing processes.
-
Bulb Firmness: The firmness of the bulb is crucial for viability. Some crocus bulbs may have baby bulbs developing on the root base, while others may have top shoots. Note that species or botanical crocus bulbs are generally smaller compared to Dutch Large Flowering Crocus bulbs. The top size species crocus corms are typically around 5 centimeters/up, while Dutch Large Flowering Crocus corms are larger, measuring about 9 centimeters/up. Smaller bulbs are usually not included in the stock, and there can be size variation due to larger corms.
-
Storage: Store crocus bulbs in a cool, dry place with low humidity, away from heat, frost, and strong sunlight. Avoid putting the bulbs in the freezer, as this can cause them to dry out or become moldy.
-
Planting Density: Plant crocus bulbs at a density of around nine bulbs per square foot. They require neutral pH, well-draining soil, and full to partial sunlight. Ideal soil is sandy loam, while clay soil should be amended with sand, peat moss, and compost. Avoid adding horse manure, chicken droppings, mushroom compost, or partially decomposed compost to crocus beds.
-
Crocus Care: Provide adequate water to established crocus beds during dry spells, but avoid overwatering as it can lead to bulb rot. Remove any weeds or competing vegetation to ensure the best growth and flowers. Apply a layer of mulch in the fall to provide insulation and protect the bulbs during winter.
Remember to follow these guidelines for successful planting and care of crocus bulbs.
Factors Affecting Crocus Blooming Time
The blooming time of crocus flowers is dependent on temperature and site conditions rather than the calendar date. Warmer horticultural zones will cause crocus to bloom earlier, while colder zones will cause them to bloom later. A long cool spring followed by rapid warming can result in earlier blooming crocus, along with other flowers like Galanthus, species tulips, and Narcissi.
Mild winters or warmer-than-usual springs can also cause crocus to bloom early. However, they may start off small and short before growing taller and larger as temperatures moderate. Additionally, crocus corms can be forced indoors over the winter by potting them up in mid-October and prechilling them for a specific period of time before bringing them into stronger sunlight for blooming.
Interesting Facts About Crocus
Crocus sativus is the specific variety of crocus that is cultivated for the purpose of collecting saffron, a highly prized spice. It is important to note that only the stigmas of the Crocus sativus flower are used to produce saffron, and no other varieties are edible.
To put into perspective the labor-intensive process of saffron production, it takes an astonishing 75,000 flowers to yield just one pound of saffron. This highlights the valuable nature of saffron as a spice.
Apart from the Crocus sativus, crocus flowers can be found in a range of colors including blue, purple, orange, yellow, and white. While the majority of crocuses do not possess a fragrance, there are certain varieties that emit a pleasant scent. These flowers typically reach a height of approximately 5 inches, contributing to the visual appeal and vibrancy of gardens and landscapes.
Common Issues and Solutions with Crocus Planting
There are a few common issues that may arise when planting crocus bulbs. If crocus bulbs are producing more foliage than flowers, it suggests a root system issue. In such cases, mature plantings may need to be dug up and transplanted in the fall.
Crocus bulbs should be planted at a depth of 2 to 3 inches and spaced about 3 inches apart. The pointed tip of the bulb should be facing up when planted. It is important to ensure that the soil is well-draining and not overly wet, as overwatering can cause rot. Dry bulbs should be discarded as they will not grow.
It is worth noting that crocuses are a favored delicacy for squirrels, who may eat the flowers. To protect the flower bed, it is recommended to cover it with mesh or wire. While coffee grounds can deter squirrels, their effectiveness for this purpose may vary.
- Crocus bulbs should be planted at a depth of 2 to 3 inches
- Spacing: 3 inches apart
- Well-draining soil is important to prevent rot
crocus bulbs can spread by themselves as a naturalizing plant or be divided and spread manually. With proper care, nutrients, and good soil, crocus bulbs can last for up to 5 years, providing stunning displays of colorful blooms. Whether in gardens, lawns, or pots, crocus flowers bring joy and beauty to any space.

Frequently Asked Questions
Do crocus multiply?
Yes, crocus have a natural instinct for multiplication. They have the ability to create more of themselves through corm offsets – small corms that grow alongside the original corm. These offsets develop over time and eventually result in new crocus plants. Additionally, in certain favorable conditions, crocus can also reproduce through self-sowing their seeds, further increasing their population. Nature has gifted crocus with efficient and diverse mechanisms to ensure their multiplication and continued existence in the wild.
Do crocuses reproduce?
Yes, crocuses are capable of reproducing. Once they have become established, these vibrant flowers have the ability to multiply and form their own colonies. Should you desire to propagate your collection and expand its size, you can carefully dig up larger clumps of crocuses during autumn and divide them into smaller ones. Alternatively, you can separate individual corms and place them in pots for nurturing.
What do crocus attract?
Crocuses exert a captivating allure that beckons both bees and native pollinators. With their enticing aroma, these flowers become a vital source of sustenance during the early springs when food is scarce. In numerous locations, crocuses offer the first glimpse of pollen, providing a lifeline for bees who struggle to find nourishment during this time. Ultimately, these vibrant blooms serve as a beacon, summoning buzzing visitors in search of sustenance and playing a crucial role in the intricate web of pollination.
Can crocus be moved?
Yes, crocus can be moved and divided to encourage their growth. In warm and sunny areas of the garden, crocus can flourish and multiply over a period of two to three years. Once the flowering has completed, it is possible to lift and separate the corms. This process can be done up to six weeks after the flowers have bloomed. The divided corms can then be replanted promptly, ideally in a location that receives full sunlight or partial shade.
