Blue False Indigo, also known as Redneck Lupine, has blue pea-like flowers in May and June, A long-lived perennial. 2010 Perennial Plant of the Year. All Baptisias are very roadside salt tolerant and dry site tolerant.
PRN Preferred: Easy to grow and does not grow too big.
'Indigo Spires' False Indigo flowers in May and June, producing 12-15" showy spikes of deep violet pea-shaped blooms. The green stems are very sturdy so the flowers are held upright above the clumps. Baptisias have deep taproots and become almost shrub-like in size as they mature. Baptisia 'Indigo Spires' is very tolerant of both dry sites and road salt. A Walters Gardens introduction.
'Carolina Moonlight' False Indigo has buttery yellow pea-shaped flowers in June over clean, bluish green foliage. A great long lived hybrid from Rob Gardner of the NC Botanical Garden in Chapel Hill.
Decedence® 'Lemon Meringue' is a new introduction from Hans Hansen's extensive breeding program. The lemon yellow pea-shaped flowers are held on tall charcoal colored stems above bluish green foliage. A tough, long lived native perennial, Baptisia 'Lemon Meringue' is a colorful addition to the back of perennial borders as well as an excellent candidate for prairie gardens and dry meadows. Decadence® Lemon Meringue is drought tolerant, deer resistant and long blooming.
Decadence® 'Vanilla Cream' False Indigo has 10" spikes of vanilla pea-shaped flowers in May and June. The petioles are dark gray, making an attractive contrast to the opening flowers. The clean disease free foliage matures to grayish green in summer, making a wide clump topped by dark charcoal round seedheads. Baptisias are very long lived perennials and are useful in the back of mixed borders as well as in meadows. From Hans Hansen's Decadence® series.
'Purple Smoke' False Indigo has bluish purple flowers in May and June. A long lived perennial, selected as a chance seedling by Bob Gardner of the NC Botanical Garden. We love the subtlety of the flower color, as well as the clean, shorter foliage. One of the native plants chosen by Piet Oudolf for the newly planted meadow garden at Delaware Botanic Gardens.
PRN Preferred: A slightly shorter variety. Very drought tolerant once established, subdued bluish flowers work well in a perennial garden.
Hardy Orchid has rosy purple flowers in May, like miniature Cattleyas. The clump will grow steadily larger, and Bletilla is dry site tolerant when established. Best planted in spring or early summer.
Heartleaf Brunnera has blue flowers in mid April to June over green foliage. Must have a moist spot. A slow spreader.
'Silver Heart' Heartleaf Brunnera blooms in April and May, with cobalt blue flowers held over stunning silver and green heart-shaped leaves. The leaves are similar to the other new silver-laced cultivars but Brunnera 'Silver Heart' has thicker, more pubescent foliage, so it tolerates our hot East Coast summers better. All Brunneras perform best with moderate but consistent moisture, and the effect of the large blue flowers over the silver foliage is spectacular in the spring.
PRN Preferred: Better, more heat resistant foliage for our East Coast summer conditions.
