Baptisia - false indigo is a tough and long-lived perennial native to S.E. USA and E. North America. The genus comprises of about 20 species which grow mostly in dry and sunny locations. In Europe it was almost absent until the end of the second millennium. But at the turn of the century it slowly became available in garden centres where mostly hybrids combining the best of each species are offered. These tall perennials exhibit a longevity of 15-20 years and make a stunning display of erect, lupine-like inflorescence.
Description of the plant:
Lemon Meringue is a baptisia hybrid bred by Hans Andrew Hansen from Walters Gardens Inc., Michigan, USA. Its lemon-yellow, pea-like flowers are composed in about 45 cm long, erect racemes and attract butterflies. It is a hybrid between b. sphareocarpa with yellow flowers and b. alba with glaucous foliage. Palmate leaves are divided into 3 ovate, blue-green leaflets. It grows vigorously about 90 cm tall and wide. Patent No. PP24280 was granted in 2014.False indigo has just one disadvantage – it is extremely slow to establish hence its high retail price. But once it does it multiplies the number of stems year after year and makes almost a shrub-like appearance owing to which it is often used as a companion plant among non-flowering shrubs and small trees. It was voted Perennial of the Year 2019 by the Czech Perennial Association.
Baptisia needs full sun and warm soil. It is not picky about soil pH but requires well-drained ground. Sand and gravel do miracles as they warm up the soil by getting rid of all excess water. Feeding is not required. In late autumn or early spring remove all stems just above ground level. Hardy to min. -34 °C (USDA zone 4), perhaps a few degrees lower.
