    • To humans

      Sweet pea plants, including the 'Lizbeth' cultivar, contain toxic amino acids, specifically beta-aminopropionitrile that can cause a condition known as lathyrism when ingested in large quantities. Lathyrism is characterized by symptoms that may include paralysis, labored breathing, and convulsions. Chronic ingestion can lead to more severe neurological effects such as muscle weakness and paralysis.

    • To pets

      Sweet pea toxicity in pets may result in similar conditions as in humans if consumed in large amounts. The plant contains toxic compounds that can cause lathyrism, which in pets might manifest as lethargy, seizures, and muscle tremors. Chronic ingestion can cause potentially irreversible paralysis and skeletal malformations.

  • water dropWater

    Sweet peas need consistent moisture to thrive, so it's important to water them regularly. The soil should be kept lightly moist but not waterlogged. During their active growing season, sweet peas may need watering once a week with about one-inch of water. In hotter, drier climates or during particularly dry spells, you may need to water twice a week. Use a gentle stream of water to avoid disturbing the soil or damaging the plant stems, and aim to water at the base of the plants to keep the foliage dry and discourage mildew.

  • sunLight

    Sweet peas prefer full sunlight for robust growth and maximum flowering. They should be placed in a spot where they receive at least 6 hours of direct sun per day. Ensure that the chosen location is not shaded by other plants or structures, as too much shade can reduce blooming and lead to weaker plants.

  • thermometerTemperature

    Sweet peas grow best in temperatures between 55 and 65 degrees Fahrenheit, making them ideal for cooler climates or for growing early in the spring. They can tolerate temperatures as low as 25 degrees Fahrenheit for short periods, but frost can damage the plants. Sweet peas may struggle and stop blooming in temperatures above 80 degrees Fahrenheit, as they prefer cooler weather.

  • scissorsPruning

    Pruning sweet peas encourages more prolific blooming and keeps plants looking tidy. Deadhead spent flowers regularly to prevent the plant from setting seed, which signals the plant to stop producing new flowers. Cut back the stem just above a set of leaves. Sweet peas should be pruned throughout their blooming season. The best time for major pruning or cutting back to manage size is in the late winter or early spring before new growth begins in earnest.

    Sweet pea 'Lizbeth' thrives in well-draining soil rich in organic matter with a pH between 6.0 and 7.5. A mixture of loamy soil, peat moss, and perlite or sand aids in drainage. Regularly adding compost will keep the soil fertile and promote vigorous growth.

  • circleLife cycle

    The life of the sweet pea 'Lizbeth' begins with seed germination, ideally in early spring after the last frost when seeds are sown in well-draining soil. The seedlings emerge and develop into climbing plants, requiring support as they grow long, twining stems. Throughout spring and into summer, the plant matures and produces fragrant, colorful flowers, attracting pollinators and potentially setting seed if flowers are left to mature. If conditions are suitable, these seeds can fall to the ground and enter a dormant phase, surviving through winter to germinate the next season. Gardeners often collect and store seeds from 'Lizbeth' sweet peas at the end of the flowering season, sowing them again the following year to continue the cycle. With proper care, including regular watering and deadheading to promote further blooming, 'Lizbeth' can provide a long flowering period before dying back at the end of the growing season.

    • Propogation time


    • Lathyrus odoratus 'Lizbeth', commonly known as sweet pea 'Lizbeth', is most frequently propagated through seed. The best time to sow sweet pea seeds is in late winter or early spring, allowing for development before the warm growing season starts. To propagate by seeds, one should first nick the seed coat with a file or soak the seeds in water overnight to encourage germination. After preparation, plant the seeds about 1 inch deep in well-drained soil and space them 2 to 3 inches apart. It typically takes about 10 to 21 days for sweet pea seeds to germinate when kept at a temperature between 55 to 65 degrees Fahrenheit (approximately 13 to 18 degrees Celsius). Once the seedlings have developed a few sets of true leaves and are strong enough, they can be transplanted to their final growing positions either in the ground or in containers.
