Lobelia laxiflora ssp. angustifolia

One of those perennial Lobelia that shouldn't be as hardy as it is but mountainous areas of southern Arizona and northern Mexico have plants with surprising hardiness. A graceful clump of thin willowy leaves on stems 15"-24" tall with a profusion of midsummer tubular red flowers with a bright yellow throat. Deciduous in winter, ours handles our brief drops to 10F with mulch. Good drainage aids in winter survival.
