Wild indigo, false indigo, or Baptisia (Baptisia spp.<\/em>)\u00a0is a long-lived U.S. native perennial (USDA hardiness zones 4-9). Plants\u00a0are deeply tap-rooted and will reward you for many years of multi-seasonal beauty. They\u2019re sometimes mistaken for Carolina lupine (Thermopsis caroliniana<\/em>).<\/p>\n\n\n\n

Modern day cultivars are hybrids of 8 Baptisia<\/em> species. Top four species are purple (B. australis<\/em>), lavender blue (B. minor<\/em>), white (B. alba<\/em>), bright yellow (B. sphaerocarpa<\/em>). Several bicolors are also available. Baptisias are in the Pea family (Fabaceae). Long-blooming baptisias last for 3 to 4 weeks in the spring garden.\u00a0Their blue-gray foliage and sturdy upright shrubby habit are pluses in the summer garden.<\/p>\n\n\n\n

Long-lived baptisias perform at their best in full sun. In the shade they bloom less and stems\u00a0are weak\u00a0and\u00a0frequently require staking. Tough deep-rooted wild indigos do not like their soils disturbed. Baptisias prefer a deep\u00a0humus-rich well-drained soil but tolerate most average soils. Mulch with organic matter to keep the soil cool and weed-free. <\/p>\n\n\n\n

Vigorous plants grow 3 to 4 feet high and 4 to 5 feet wide after 3 to 5 years. Do not overcrowd. Newly planted baptisias should be watered until established, usually within\u00a01-2\u00a0year.\u00a0Plants are slow to establish and begin blooming with only a few flowers in their first year and are heavily flowered within 3 to 4 years.\u00a0<\/p>\n\n\n\n

In early spring add 1-2 handfuls of a slow-release fertilizer around new plants. Older\u00a0well-established plants require little to no fertilizer as they produce\u00a0their own nitrogen. Yellowing of leaves in the summer is a symptom of iron deficiency or high soil pH. In such cases, feed with chelated iron or an acid-based fertilizer like Schultz\u2122 or Miracid\u2122.\u00a0Established plants are heat and drought tolerant and are almost invincible to disease and insect\u00a0problems.<\/p>\n\n\n\n

Stunning stalks of colorful pea-like, non-fragrant flowers appear in mid-spring. Cut blooms last 3-4 days indoors. Flowers stalks\u00a0give way to black seedpods by late July. Black capped chickadee, finches, and sparrows will feed on seeds.\u00a0Gardeners may opt to remove the seed pods before they mature. Flower arrangers utilize the ripe blacken seedpods in arrangements.<\/p>\n\n\n\n

Cultivars with the deeper shades of blue and yellow blooms stand out in a garden. Popular cultivars from North Carolina sources and Chicago Botanical Garden breeders include: \u2018Purple Smoke\u2019 (lavender flowers), \u2018Solar Flare\u2019 (yellow), \u2018Alba\u2019 (white), and \u2018Twilight Prairie Blues\u2019. Walters Gardens in Michigan developed the Decadence\u2122 Series which are pictured above.<\/p>\n\n\n\n
