Find answers to common questions about Black Sweet Pea Seeds, their flower colors, and growing requirements.
Many flowers sold as black sweet peas have very deep purple, burgundy, or maroon petals that appear nearly black in certain lighting. The exact color depends on the cultivar, so check the supplier's photographs and variety description before purchasing.
Sweet peas generally prefer cool growing conditions. In regions with mild winters, seeds can often be sown in fall. In colder climates, early spring planting is common once the soil can be worked. Local climate and cultivar recommendations should determine the timing.
Sow fresh seeds in suitable, well-drained growing medium and keep it evenly moist. Some sweet pea seeds have hard seed coats and may benefit from soaking or careful scarification according to supplier instructions. Avoid waterlogged soil, which can cause seeds to rot.
