Porterweeds are one of the most reliable nectar producers in our gardens. These are tropical shrub-like perennials that produce tall, elongating spikes of Verbena-like flowers and they can flower continually from spring until frost. The nectar rich flowers attract a variety of pollinators but especially hummingbirds, butterflies, and long-tongued bees like Bumblebees and Carpenter Bees. This is consistently one of the most common plants that we have seen in butterfly houses along with Pentas and Lantana. Where not hardy Porterweeds make worthy annuals. Provide them with half or more of a day of direct sunlight and average moisture in a fertile soil with average or better drainage.
Deep indigo 1/4" blooms adorn the long spike-like bloom stems from spring to frost above the rich green glossy foliage. Blue Porterweed is an intermediate growing Porterweed and has a fairly dense upright habit. An excellent choice for butterfly gardens or in containers. Also known as Blue Snakeweed, Verbena Azul, Cayenne Snakeweed. Item# 330.
