I planted the seed late -- probably mid-June -- and of course in a less than ideal site out of full sun. Mirabilis longiflora from Select Seeds opened its ethereal blossoms this morning, and it was worth the wait for its beauty and novelty. The cultivar name for this relative of the Four O'Clock is 'Fairy Trumpets'. In its native range - Texas, Arizona and New Mexico - it blooms after the spring rains and can grow to 5 feet tall. Like the common Four O'Clock (Mirabilis jalapa), the plant is poisonous.
