To ensure optimal growth and blooming, Persian buttercups thrive when planted in a location that receives full sun exposure. This means providing them with at least six hours of sunlight on most days. By selecting a planting site that offers abundant sunlight, you can encourage the best possible development of these flowers.


Persian buttercups have a preference for sandy or loamy soil that possesses excellent drainage capabilities. It is beneficial to cultivate them in soil that allows water to pass through easily, preventing waterlogging and ensuring the roots receive adequate oxygen. If your soil tends to be heavy or poorly draining, you can enhance it by incorporating compost or opting for raised garden beds, which allow you to have more control over the soil composition.


While it is not mandatory to soak the bulbs before planting them, if you choose to do so, it is important not to overdo it. A soaking period of one to four hours is sufficient to avoid encouraging mold growth. After planting, it is crucial to provide the bulbs with a thorough watering. However, once the initial watering is complete, it is advisable to withhold further watering until signs of growth appear. This precautionary measure helps prevent rot. Once the Persian buttercups have become established, they prefer moderately moist soil.

Temperature and Humidity

Persian buttercups thrive in cooler spring weather and exhibit their best growth during this season. As summer temperatures exceed 90 degrees Fahrenheit, these plants tend to enter a dormant state. To prolong their growing period and keep the roots cool, it is beneficial to apply a layer of mulch around the plants. This protective layer helps to maintain lower soil temperatures and supports the continued development of the Persian buttercups. While they are not excessively sensitive to humidity levels, it is important to note that very high humidity can potentially lead to bulb rot and the demise of the plant.


Before planting the Persian buttercup corms, it is recommended to incorporate some compost or bulb fertilizer into the soil of the chosen planting site. This provides essential nutrients for the plants’ growth and development. If you are growing them in containers, a biweekly application of water-soluble fertilizer is advisable. Follow the instructions on the product label to determine the appropriate amount of fertilizer to use. This regular feeding ensures that the Persian buttercups receive the necessary nourishment to thrive and produce vibrant blooms.

To maintain an appropriate shape and size when keeping Persian buttercup indoors, you have the option to trim the foliage as desired. This helps in controlling the plant’s growth and ensures it remains visually pleasing in an indoor setting. Whether grown indoors or outdoors, it is recommended to deadhead the faded flowers. Removing these spent blooms promotes the production of more flowers and contributes to a neater appearance. However, if you are growing Persian buttercup as a perennial in the garden, it is important not to trim the foliage after blooming. Allowing the foliage to naturally die back plays a crucial role in the plant’s life cycle. During this period, the foliage absorbs sunlight and vital nutrients, which are then stored in the corm. These stored resources provide nourishment for the following season’s growth and flowering.

Propagating Persian Buttercup

You have two straightforward methods for propagating Persian buttercup: division and seed propagation.


In the fall, when opting for division as the propagation method, use a shovel to carefully dig up the corms. Many of these corms will have produced offsets or small seed corms. If your hardiness zone is 8 or higher, you can easily divide the corms using a sharp knife. Plant the offsets in a new location, ensuring that they are positioned with the fingers pointing downward, and bury them about one to two inches deep in the soil. Thoroughly water the newly planted offsets and maintain even moisture in the soil by watering every couple of days. After a few weeks, new shoots will emerge from the planted offsets, signifying successful propagation.

Seed Propagation

Another method to propagate Persian buttercup is through seeds. Collect the mature seeds from the plant and sow them in a well-prepared seed-starting mix during the appropriate planting season. Provide the seeds with adequate moisture and warmth to encourage germination. As the seedlings develop, transplant them into individual containers or a suitable garden area, following proper spacing recommendations.

Storage for Winter (below Zone 8)

If you reside in a hardiness zone below 8, Persian buttercup is typically grown as an annual. However, you can still preserve the corms during winter for replanting in the following spring. After harvesting the corms, remove excess dirt and store them in a cool, well-ventilated location away from direct sunlight. Using a crate or box filled with coir, a sustainable alternative to peat moss, helps maintain appropriate moisture levels. In the spring, soak the corms in warm water for one hour to prepare them for planting, and then follow the planting instructions mentioned earlier to establish them in the desired location.

How to Grow Persian Buttercup From Seed

Growing Persian buttercup from seeds is another viable method of propagation. Follow these steps to successfully grow them from seeds:

  1. Collecting Seeds

When the flowers of the Persian buttercup start to fade, cut off the flower heads. Keep in mind that seeds obtained from hybrid varieties may not produce plants that resemble the parent plants accurately.

  1. Drying the Seeds

Place the cut flower heads in a paper bag and allow them to dry for approximately one week. This drying period helps in the maturation of the seeds.

  1. Seed Extraction

After a week, gently shake the bag to dislodge the seeds. Be cautious as the seeds are small, so open the bag carefully to avoid scattering them.

  1. Indoor Sowing

Start the seeds indoors a few weeks prior to the final frost date in your region. Ensure that the soil is evenly moist, and sow the seeds on top of it. Maintain daytime temperatures between 60 to 70 degrees Fahrenheit (15 to 21 degrees Celsius). It is important to keep the seeds away from direct sunlight and drafts.

  1. Germination

Germination usually occurs within approximately two weeks. During this period, provide a good light source for the seedlings to promote healthy growth.

  1. Transplanting

Once the seedlings have developed four sets of true leaves, they are ready to be transplanted into separate containers. However, refrain from planting them outdoors until all risks of frost have passed in your area.

  1. Hardening off

Before transplanting the seedlings into the garden, it is essential to gradually acclimate them to outdoor conditions. This process, known as hardening off, involves exposing the seedlings to outdoor elements such as sunlight, wind, and temperature fluctuations over a period of several days. This helps the seedlings adjust to the outdoor environment and reduces the risk of transplant shock.

Potting and Repotting

Persian buttercups are commonly cultivated in containers, especially in regions outside their hardiness zones. When potting them, select containers that have sufficient drainage holes at the bottom. Fill the container with a well-draining, all-purpose potting mix. If planting multiple corms in the same container, ensure they are spaced three to four inches apart. Bury the corms about two inches deep in the soil, making sure they are adequately covered. After planting, water the corms thoroughly, and place the container in a location that receives full sun to facilitate optimal growth and blooming.


In regions within their hardiness zones, overwintering Persian buttercups is relatively straightforward. Before winter arrives, trim the plants back to ground level and consider adding a layer of mulch to provide some protection. However, in areas with harsher winters, the success of overwintering corms in the ground is uncertain. If you decide to attempt overwintering, dig up the corms and store them in a dry location. A medium like coir can be used for storage. It is important to note that storing corms in colder regions often yields limited success.

For Persian buttercups grown in containers, it is advisable to bring them indoors to a warm location for the winter season. This protects the plants from the adverse conditions and helps ensure their survival during the colder months. By providing a suitable indoor environment, you can help maintain the health and vigor of your Persian buttercups until the arrival of warmer weather.
