Iris tuberosa aka Snake's Head Iris

Taxonomy

Iris tuberosa, formerly known as Hermodactylus tuberosus, is a species of tuberous flowering plant belonging to the Iris genus. It is also commonly referred to as snake's-head, snake's-head iris, widow iris, black iris, or velvet flower-de-luce. This non-rhizomatous perennial features lance-shaped, glaucous green leaves that emerge during winter or early spring. The flowers, which appear on stems up to 40cm in height, are a striking combination of greenish-yellow standards and purplish-brown to blackish falls. Native to the Levant, this Iris species stands out due to its quadrangular leaves and unique flower colors. Although it may not be conventionally considered beautiful, its somber tints possess a certain charm. It is a hardy plant that thrives in an eastern aspect, according to Miller. Iris tuberosa typically blooms in April or May and can be propagated easily through offsets from the roots. While seed production is rare, the plant is useful and can be removed by wearing gloves and gently pulling it out with the root system, using a shovel for convenience if desired.

How to care for Snake's Head Iris

Difficulty

Snake's Head Iris presents a moderate level of care, which allows plant enthusiasts with some experience to expand their skills and knowledge.

Water

Snake's Head Iris should be watered regularly, allowing the soil to dry out between waterings.

Soil

When growing Snake's Head Iris, it is important to pay attention to the soil type you are using. This plant is very sensitive to dry soil and needs a potting soil that retains moisture. A good soil should still be well-draining and contain lots of organic matter. Coco coir or sphagnum moss are great options to provide the Snake's Head Iris with the nutrients and moisture it needs. The added organic matter will also help the soil retain water and prevent the Snake's Head Iris from drying out too quickly. Before planting, make sure to mix compost or manure into the soil for extra nutrients. Also, make sure to water the Snake's Head Iris regularly, making sure to keep the soil evenly moist but never soggy. With the correct soil and watering regimen, the Snake's Head Iris will thrive and bring lots of beauty to your home.

Lighting

Snake's Head Iris thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Snake's Head Iris.

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 Snake's Head Iris 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.
