description for "Sweet Peas: Lathyrus odoratus 'Cupani'"

‘Cupani’ is an especially strong blooming strain - a heat-tolerant treasure heirloom. Its ancestry can be traced to the first wild sweet-peas from Sicily named for Father Francis Cupani, the Italian monk who discovered and sent them back to England in the 17th century. These intensely perfumed, beautifully bicolored flowers have petals of deep maroon-purple and orchid-violet. The fragrance of these classic simple blossoms truly wafts in the air, delighting every passerby. Anyone who has ever grown sweet peas wants them close by, where their delicious fragrance can permeate the air. A cool climate favorite for northern gardeners in the summer. Grow seedlings to enjoy this coming winter in southern gardens, or use in northern garden rooms and greenhouses. Sweet-peas bloom best before the weather gets too hot, so if spring planting, sow as early as possible. In regions where summer heat comes on fast, they’ll appreciate a spot with afternoon shade. Anchor climbing supports well as these vines will grow dense and heavy with bloom. Protect seedlings from birds, slugs and snails, especially if fall planting. Mulch and keep well-watered for best flower production. For longest bloom, pick flowers often and keep faded blossoms cut. – edited by dtd pbcouchman
