Spring vetchling, as it's commonly known, is a perennial plant that typically blooms in the springtime. It possesses a bushy yet compact appearance, with stems that are adorned with pairs of small, rounded leaves that are a vibrant green color. These leaflets are generally smooth-edged, giving the foliage a neat and well-kept appearance. As the days start to lengthen, the plant brings forth a profusion of colorful flowers. These blooms are characterized by their butterfly-like shape, which is typical of plants in its family. The flowers range in hue from purplish-pink to bluish-violet, often with a gradient or mottled pattern that adds to their allure. After the flowering season, the plant produces pods which encase the seeds, and these pods often have a slightly fuzzy texture. The overall form of the spring vetchling is somewhat rounded and full, creating an appealing visual display that can add a touch of early color to gardens and natural settings.

  • skullToxicity

    • To humans

      The plant known as the spring vetch is considered mildly toxic to humans if ingested. However, the level of toxicity in Lathyrus vernus typically does not cause severe reactions. Some species in the Lathyrus genus contain a compound known as ODAP (beta-N-oxalyl-L-alpha,beta-diaminopropionic acid), which can lead to a condition known as lathyrism if consumed in large quantities over time. Lathyrism is characterized by symptoms such as muscle weakness and paralysis, particularly in the lower limbs. Consuming parts of spring vetch may lead to gastrointestinal upset, characterized by nausea, vomiting, diarrhea, and abdominal pain.

    • To pets

      The plant referred to as spring vetch is also mildly toxic to pets, including cats and dogs. As with humans, the severity of the symptoms typically is not high unless consumed in large amounts. Pets that ingest parts of the spring vetch may experience mild gastrointestinal upset, with symptoms such as vomiting, diarrhea, and possible abdominal discomfort. If you suspect your pet has ingested a significant amount of spring vetch or is showing signs of severe distress, you should contact a veterinarian.

  • water dropWater

    Spring pea, or Lathyrus vernus, prefers consistent moisture, especially during its active growing phase in the spring and early summer. Ensure the soil is well-draining and remains evenly moist but not waterlogged. You may need to water the plant once a week with about one gallon of water, although you should always check the soil moisture before watering; it should be damp to the touch, about an inch below the surface. During the dormant phase in late summer to early fall, you can reduce watering. Overwatering can lead to root rot, so moderation is key.

  • sunLight

    Spring pea thrives in partial shade to full sun, so choose a spot that receives at least four hours of direct sunlight per day, but is also protected from the hot afternoon sun, which can be too intense. An ideal location would provide morning sunlight and dappled shade in the afternoon, which would mimic the woodland edges where it naturally grows.

  • thermometerTemperature

    Spring pea can withstand a fair range of temperatures, but thrives best in moderate conditions. It can survive minimum temperatures down to around 20°F, while its preferred growing range is between 60°F and 70°F. Excessive heat can be detrimental to the plant, so avoid placing it in locations where temperatures exceed 80°F for prolonged periods.

  • scissorsPruning

    Pruning spring pea is essential for maintaining its shape and encouraging new growth. After flowering, usually in late spring or early summer, prune the plant by cutting back the spent flower stems. This can promote a second, albeit less abundant, flowering. Prune lightly once a year to remove any dead or weak stems and to keep the growth in check. The best time for pruning is just after the plant has finished its main flowering period.

  • bambooSoil

    Spring vetch requires well-drained soil enriched with organic matter, in a mix of two parts garden soil, one part compost or leaf mold, and one part sand or perlite. The ideal pH for this plant should range from 6.0 to 7.0 to support healthy growth and flowering.

  • plantRepotting

    Spring vetch does not typically require frequent repotting; it should be repotted only when it has outgrown its current container, typically every 2-3 years to refresh the soil and provide room for growth.

    Spring vetch prefers moderate humidity levels but is quite adaptable and does not have specific humidity requirements; it thrives in the humidity levels found in most outdoor environments.

  • circleLife cycle

    Lathyrus vernus, commonly known as spring vetchling or spring pea, begins its life cycle as a seed, sown in well-drained soil usually in autumn or early spring. Upon germination, which requires a period of cold stratification to break dormancy, the seedlings develop roots and shoots, emerging from the soil as small plants. As spring progresses, the plant enters the vegetative stage, producing compound leaves that capture sunlight for photosynthesis and support further growth. By late spring to early summer, the spring vetchling enters the flowering stage, where it produces showy purple, pink, or even white flowers, which are pollinated by insects, leading to fertilization. Following pollination, the plant develops pods containing seeds, signifying the reproductive stage. Once mature, the pods dry and release seeds, completing the life cycle and enabling the spring vetchling to proliferate in the environment.

    • Propogation time


    • The Spring Vetch, commonly known as Lathyrus vernus, can be propagated by division or from seed, but the most popular method is seed propagation. To propagate the Spring Vetch using seeds, one should collect the seeds when the pods have matured, which typically occurs in late summer. Once collected, the seeds need to be sown immediately or can be stored and then stratified for several weeks before the spring sowing to ensure germination. Sow the seeds about 1/4 inch deep (approximately 6 mm) in a well-draining soil mix. Keep the soil consistently moist but not waterlogged, and with patience and proper care, seedlings should appear in the coming spring. Seed propagation captures the genetic diversity of the species and can result in a pleasing variation among the progeny.
