Largeseed Forget-me-not (Myosotis macrosperma)

I. Appearance and Characteristics 

Myosotis macrosperma, commonly called largeseed forget-me-not, is a species of flowering plant in the borage family (Boraginaceae). It is native to North America, where it found in the eastern United States and Ontario, Canada. It is found in a wide variety of natural habitats, including areas of bottomland forests, mesic forests, and prairies. It appears to be associated with nutrient rich soils. It is tolerant of disturbance, and can be found in highly degraded communities such as pastures and fallow fields.

Myosotis macrosperma is an herbaceous annual. It blooms in the spring, where it produces a cyme of white flowers. It differs from the similar-looking Myosotis verna (which occupies much of the same geographic range) in several characters. Myosotis macrosperma can be distinguished by its longer inflorescence nodes, larger and more deciduous calyx, and larger mericarps.

The stem of largeseed forget-me-not is characterized by its ascending to erect posture and angled geometry. Typically green in color, the stem features a covering of fine hairs, which give it a slightly rough texture. The thickness of the stem varies but generally measures around 0.1 inch (2-3 mm) in diameter. It exhibits an erect, often branched pattern, supporting the plant’s overall structure. The combination of these features makes the stem of largeseed forget-me-not distinct and identifiable for plant enthusiasts.

The leaves of largeseed forget-me-not are green, lanceolate, and covered with fine hairs, giving them a slightly rough texture. They feature a single, distinct midrib that runs the length of each leaf. Typically, the leaves are alternate in arrangement and primarily situated at the base of the plant. On average, these leaves measure about 2-4 inches (5-10 cm) in length. The lanceolate shape is slender and tapers to a point at both ends, providing a recognizable profile for identification.

The flowers of largeseed forget-me-not are tiny and feature five white petals. Arranged in cymes, these blooms appear in the spring. Each flower includes delicate, green linear bracts. The overall shape is star-like, with each petal measuring approximately 0.1-0.2 inches (3-6 mm) in length. This arrangement produces a dainty and elegant appearance. Though small, these white flowers are a distinct springtime identifier for largeseed forget-me-not.

The fruit of largeseed forget-me-not is comprised of greenish-brown to brown nutlets that exhibit a burr-like texture, facilitating dispersal by adherence to fur or clothing. These nutlets are typically small and hard, with a rough exterior that enhances their ability to cling to passersby. The distinctive textural quality and coloration of the fruit are integral characteristics that aid in the recognition of this species among novice plant enthusiasts. The nutlets’ size and hitchhiking mechanism are remarkable features that can be observed when the fruit has matured on the plant.

II. How to Grow and Care

Sunlight

Largeseed forget-me-not thrives under full sun conditions, which means it performs best when it receives at least 6 hours of direct sunlight daily. Although largeseed forget-me-not tolerates partial sun, where the plant receives some dappled sunlight, or even full shade, these less-than-ideal conditions may result in leggier growth and reduced flowering. To maximize largeseed forget-me-not’s health and growth potential, ensure outdoor planting in locations that offer unfiltered sunlight. The plant naturally adapts to light variance with leaf adjustments, but consistently providing the ideal light ensures the most vigorous growth and bloom production.

Watering

Originating from moist habitats, largeseed forget-me-not thrives in environments that emulate the consistent moisture of its native setting. This species exhibits a preference for regular hydration without being waterlogged, maintaining a balance that supports its health and growth. Watering should occur once every week to align with its natural rhythm. Typically grown outdoors due to its affinity for natural light and climate cycles, largeseed forget-me-not benefits greatly during the growing season when rain patterns complement its watering needs.

Soil

Largeseed forget-me-not is a resilient wildflower that thrives in well-draining soil with moderate moisture.

Fertilizing

For largeseed forget-me-not, fertilization promotes robust growth and prolific blooms. Opt for balanced fertilizers during the growing season, shifting to high-nitrogen ones pre-flowering. Apply every 4-6 weeks, roughly a teaspoon per plant, avoiding over-fertilization to prevent leaf burn. Seasonal adjustments are crucial; less frequent in dormant winter months. Implement slow-release formulas for consistency, and ensure moist soil before application to protect roots. Safety tip: wear gloves and wash hands post-application. Novices and experts should aim for precision with doses to maintain largeseed forget-me-not vibrancy.

Pruning

For largeseed forget-me-not, characterized by its small blue flowers and preference for cool, moist conditions, timely pruning enhances plant vigor. Ideally, prune in Spring after flowering to promote bushiness. Summer or Fall deadheading encourages reblooming while maintaining shape. Carefully remove spent flowers and thin out overcrowded areas to allow light and air circulation, which are vital for its health. Avoid heavy cutting back to prevent stress. Regular, light pruning is key for this species’ longevity and aesthetic appeal.

Propagation

Largeseed forget-me-not thrives when propagated through sowing. For successful establishment, sow seeds in well-draining soil combined with ample organic matter to ensure nutrients are readily available. Moisten the soil gently after sowing for optimal seed-soil contact, promoting efficient germination. Once growth begins, thin out seedlings, allowing robust development for the survivors by reducing competition. Regular watering, careful monitoring, and a stable environment will facilitate a higher success rate in largeseed forget-me-not propagation efforts.

Transplanting

The prime window for relocating largeseed forget-me-not spans from the emergence of early spring’s tender warmth to the cusp of summer’s threshold. Choosing a site with dappled light ensures largeseed forget-me-not thriving post-transplant growth. A guiding tip: gentle handling secures largeseed forget-me-not delicate roots during this pivotal transition.
