Algerian Iris Iris unguicularis 'Mary Barnard'
ABOUT
Iris unguicularis 'Mary Barnard', commonly known as the Algerian iris, is an ornamental plant heralded for its strikingly beautiful blooms that appear in the winter to early spring months. The flower petals showcase a rich, deep purple hue, which is often accentuated with striking, contrasting white markings and yellow or orange beards in the center that add a vibrant splash of color to the otherwise dormant landscape. These long and slender petals are elegantly shaped, gracefully arching away from the center, giving the bloom a delicate and intricate appearance. The foliage of the Algerian iris is also noteworthy. It consists of long, narrow leaves that are a deep green color. These leaves can remain evergreen in milder climates, lending a touch of greenery throughout the year. They often form a dense clump of strap-like foliage that fan out from the base of the plant, creating an attractive, grassy backdrop for the exquisite flowers. When in bloom, the Algerian iris 'Mary Barnard' is admired for its resilience to cold temperatures and its ability to bring color to the garden during the cooler part of the year, a time when many other plants are not in flower. The blooms are not only visually appealing but also have a delightful fragrance that can be a pleasant surprise in a season often lacking in scented flowers. Overall, the Algerian iris 'Mary Barnard' is praised for its striking flowers and the touch of elegance and winter interest it adds to landscapes and gardens.

- Toxicity
To humans
Iris unguicularis, commonly known as Algerian Iris, is not generally considered highly toxic to humans. However, the rhizomes (underground stems) of irises contain irisin, iridin, or irisine which can cause gastrointestinal symptoms if ingested. Eating parts of the plant might lead to stomach pains, nausea, vomiting, and diarrhea. Handling the plant, especially the rhizomes, can sometimes cause skin irritation due to the presence of these compounds. In the case of severe ingestion, medical attention should be sought, but mild cases may only result in discomfort.
To pets
The Algerian Iris poses similar risks to pets as it does to humans. If pets, such as cats or dogs, ingest parts of the plant, particularly the rhizomes, they could experience symptoms such as vomiting, diarrhea, salivation, or lethargy. The toxic compounds irisin, iridin, or irisine present in the Algerian Iris can cause these gastrointestinal disturbances in pets. While generally not life-threatening, if a pet consumes a large amount of the plant, it is advisable to contact a veterinarian for guidance due to the risk of gastrointestinal upset or more severe reactions.

- Water
Algerian iris should be watered deeply to ensure moisture reaches the root zone, particularly during the growing season from fall to early spring. Depending on climate conditions, it might need watering every 7 to 10 days. During the hot, dry summer months, watering can be reduced to a minimal as the plant is drought tolerant. It's essential to water the Algerian iris with approximately one gallon of water for established plants, ensuring not to waterlog the soil as it prefers well-draining conditions.
- Light
Algerian iris thrives best in full sun to partial shade. Ideally, it should receive at least 6 hours of sunlight per day, but it can still perform well in a spot with bright, indirect light or dappled shade. The plant's flowering may be reduced in too much shade, so choose a location where it can receive ample light for optimal blooming.
- Temperature
The Algerian iris can withstand temperatures as low as 10°F and as high as 90°F, being quite resilient to temperature fluctuations. The ideal temperature range for this plant is between 60°F and 75°F during the growing season. It can survive short periods of colder winter weather, provided it's not prolonged and the ground isn't frozen for an extended period.
- Pruning
Pruning Algerian iris should be done after flowering to maintain plant health and appearance. Remove spent blooms to encourage more flowers and cut back any damaged or diseased leaves. The best time for a thorough cleanup is late summer or early fall, where you can trim the foliage to about 6 inches from the ground. Pruning is generally recommended once a year.
- Cleaning
As needed
- Soil
Algerian Iris 'Mary Barnard' thrives in well-draining soil rich in organic matter; a mix with loam, compost, and coarse sand is ideal. The recommended soil pH is slightly acidic to neutral, ranging from 6.0 to 7.0 for optimum growth.
- Repotting
Algerian Iris 'Mary Barnard' typically does not need frequent repotting and can often remain in the same pot for several years. However, it should be repotted if it becomes root-bound or the soil is exhausted, generally every 3 to 5 years.
- Humidity & Misting
Algerian Iris 'Mary Barnard' is tolerant of a range of humidity levels as long as it is not in a constantly wet environment; average room humidity is typically sufficient.
- Suitable locations
Indoor
Ensure bright light, cool temps, and good air circulation.
Outdoor
Plant in full sun to partial shade, shelter from harsh wind.
Hardiness zone
7-9 USDA
- Life cycle
Iris unguicularis 'Mary Barnard', commonly known as Algerian iris, begins its life cycle as a seed, which germinates in favorable conditions with adequate moisture and temperature, typically in autumn. The seedling develops a root system and foliage in the form of sword-shaped leaves. Over time, it establishes a strong rhizome underground from which new growth emerges. The plant enters a vegetative state where it continues to grow leaves and strengthen its rhizome. Following a period of cooler temperatures in winter, the Algerian iris enters its flowering stage, usually between late winter and early spring, producing purple-blue flowers with a pleasant fragrance. After pollination, the flowers produce seeds, and the plant may go dormant during the hot summer months, completing its life cycle.
- Propogation
Propogation time
Late summer to early fall
Iris unguicularis 'Mary Barnard', commonly known as Algerian iris, is typically propagated by division, a method most commonly employed after the flowering season has ended. For optimal results, this is best done in late summer, when the plant is somewhat dormant. With careful division, you can ensure a successful propagation by separating the rhizomes, the horizontal underground stems capable of producing the upright leafy shoots. Use a sharp knife to cut the rhizomes into pieces, ensuring each section has at least one fan of leaves. Plant these divisions about an inch deep (2.54 cm, roughly 6.4 mm) in well-draining soil that receives full sun to light shade, spacing them about 12 to 24 inches apart (30 to 61 cm). Water the newly planted divisions well to settle the soil around the rhizomes and to help establish them. With proper care, these divisions will grow into new, vibrant Algerian iris plants.
