    • To humans

      Sweet pea, including the variety 'Isabella Cochrane', contains toxic amino acids, particularly in the seeds and seed pods, which can pose a hazard if ingested in large quantities. Symptoms of sweet pea poisoning typically include lethargy, convulsions, and possibly paralysis. More severe cases can lead to a condition called lathyrism, which is characterized by potentially irreversible paralysis of the lower limbs and neurological damage. Ingestion of the flowers or leaves in small amounts is usually not harmful, but ingestion of seeds and pods should be avoided.

    • To pets

      Sweet pea, including the 'Isabella Cochrane' variety, is also toxic to pets because of its amino acid content, especially in seeds and seed pods. If pets consume these parts of the plant, they can experience symptoms such as vomiting, lethargy, convulsions, and even paralysis. Chronic ingestion could lead to a condition called lathyrism in animals, similar to that in humans, which involves neurological damage and is potentially irreversible. Pet owners should prevent animals from ingesting any part of the sweet pea plant to avoid these risks.

Pruning
  • water dropWater

    When watering Sweet Pea 'Isabella Cochrane', it is essential to keep the soil consistently moist but not waterlogged. Water the plant deeply once a week with about one to one and a half gallons of water, ensuring the water penetrates the soil thoroughly. During periods of prolonged heat or drought, increase the frequency to twice a week. Always check the top inch of the soil before watering; if it feels dry, it's time to water. In the cooler months, reduce the watering frequency to avoid waterlogging, which can lead to root rot.

  • sunLight

    Sweet Pea 'Isabella Cochrane' thrives in full sun to partial shade. Place the plant in a location where it receives at least six hours of direct sunlight every day. The best spot would be one where morning light is abundant, as intense afternoon sun can sometimes be too harsh, especially in hotter climates. However, ensure that there is some light shade during the hottest part of the day to prevent scorching of the leaves.

  • thermometerTemperature

    Sweet Pea 'Isabella Cochrane' prefers cooler temperatures, with ideal conditions ranging between 55°F and 65°F. It can tolerate a minimum temperature of around 50°F but should not be exposed to frost. The maximum temperature the Sweet Pea can endure is approximately 75°F before it begins to show signs of stress. These plants will bloom best in the cooler temperatures of late spring to early summer.

  • scissorsPruning

    Sweet Pea 'Isabella Cochrane' should be pruned to encourage bushier growth and more blooms. Pinch out the tips of young plants to stimulate side shoots. As the season progresses, deadhead the spent flowers regularly to promote continuous blooming. The best time for pruning is after the initial flowering when you can also cut back some of the plant's length to rejuvenate it. Prune Sweet Peas after the main harvest, but before the seeds have set, if you're not saving them for next year.

  • circleLife cycle

    The life of the sweet pea 'Isabella Cochrane' begins with seed germination, which requires a well-drained soil and temperatures between 55-65 degrees Fahrenheit. Following germination, the plant enters the vegetative phase, during which it develops its distinctive compound leaves and tendrils that allow it to climb. Next is the flowering stage, where the plant produces fragrant, attractive flowers in shades of mauve, typically beginning in late spring and continuing through the summer. After pollination, the plant sets seed in the form of pods that once mature, can be harvested for the next season's planting. As an annual, the sweet pea completes its life cycle within one year and dies after seed production, requiring new seeds to be sown for continuation. Overwintering is not part of the sweet pea's cycle, as they do not tolerate frost and will not survive cold winter temperatures.

  • sproutPropogation

    • Propogation time

      Spring to early summer

    • Propogation: The sweet pea, Lathyrus odoratus 'Isabella Cochrane', is typically propagated through seeds. The best time to sow sweet pea seeds is in late winter or early spring to ensure they are well-established when the warmer weather arrives. A popular method of propagation for sweet peas involves soaking the seeds for 24 hours in room temperature water to soften the seed coat and promote germination. After soaking, the seeds can be sown into pots filled with a well-draining seed starting mix, placing them about an inch deep. The pots can then be kept in a bright, cool place and kept consistently moist. Germination usually occurs within 7 to 14 days. Once the seedlings have grown and the risk of frost has passed, they can be transplanted outdoors into a sunny spot with support for their climbing habit.
