amethyst allium 'Red Mohican'


The Allium amethystinum 'Red Mohican', commonly known as the Red Mohican allium, is an ornamental onion featuring distinctive blooms. The flower heads boast a unique shape, which resembles a mohawk haircut, hence its name. These blossoms are characterized by a cluster of star-shaped, reddish-purple florets that are tightly packed together, creating a dense, striking appearance. The flower heads often have a tuft of longer florets that grow at the top, giving them a somewhat punk, rebellious look. The sturdy stems supporting these striking flower heads are generally green, blending seamlessly into the plant's foliage. The leaves of the Red Mohican allium are usually strappy and glossy, with a deep green color that complements the vibrancy of the blooms. Their texture can be somewhat fleshy, a common trait among plants in this family. The foliage tends to form a clump at the base of the plant, setting an aesthetic foundation for the dramatic flowers that rise above. The Red Mohican allium blooms typically appear in the late spring to early summer, contributing bursts of color to gardens during this time. Its showy florets not only add visual interest but also attract pollinators like bees and butterflies, making it a beneficial addition to any ecological garden setting. Though its dimensions are excluded from this description, the plant's bold blooms are the stand-out feature that leave a lasting visual impact.

  • water dropWater

    The Red Mohican Allium should be watered deeply to ensure the water reaches the roots, but only when the soil feels dry to the touch; overwatering can cause the bulbs to rot. During the growing season, this usually means watering once every week or every two weeks, depending on climate conditions, with about 1 gallon of water per plant each time to maintain consistent soil moisture. During dormant periods, especially in winter, reduce watering significantly, only ensuring that the bulbs do not completely dry out.

  • sunLight

    The Red Mohican Allium thrives in full sun conditions, meaning direct sunlight for at least 6 to 8 hours a day. It is best positioned in a spot where it can receive ample unfiltered sunlight throughout the day to ensure healthy growth and prolific blooming.

    Red Mohican Allium prefers a temperate climate and can tolerate a range of temperatures; ideally, it thrives between 50°F and 80°F. It is hardy and can withstand minimum temperatures down to around 20°F. Avoid exposing the plant to extreme heat above 90°F for prolonged periods, which can be detrimental to its health.

  • scissorsPruning

    Prune the Red Mohican Allium after flowering by deadheading spent blooms to encourage the bulbs to store energy for the next season rather than seed production. Cut back the foliage only after it has turned yellow and died back naturally, usually in late summer or early fall. This allows the plant to photosynthesize and gather energy for the next growing season.

  • circleLife cycle

    Allium amethystinum 'Red Mohican', commonly known as the red mohican allium, starts its life cycle as a bulb, which undergoes a period of dormancy typically during cold weather. In spring, the bulb breaks dormancy, sending up green shoots that develop into sturdy stems with strap-shaped leaves. By late spring to early summer, the plant produces distinctive flower spikes topped by dense umbels of star-shaped burgundy-red flowers. After blooming, the plant sets seed, which can be dispersed by wind or animals, leading to potential new plants if conditions are favorable. Throughout the summer, the foliage of the plant begins to die back as the bulb enters a phase of senescence and preparation for the next dormant period. The cycle continues as the bulb overwinters in the soil, waiting for the next growing season to start the process again.

      Late winter to early spring

    • Allium amethystinum 'Red Mohican', also known as Ornamental Onion, is typically propagated through division, the most popular method for multiplying this plant. This process generally takes place during the plant's dormant period, often in the fall after the foliage has died back or in early spring before growth resumes. To propagate by division, carefully dig up the clump of bulbs and gently separate them, ensuring that each section has at least one growth point or shoot. Replant the sections immediately at the same depth from which they were taken, typically 2-4 inches (about 5-10 cm) deep, spaced about 8 to 12 inches (approximately 20-30 cm) apart to give them room to grow. Water the new plantings thoroughly to settle the soil and help with root establishment.
