Amorpha fruticosa - the false indigo or indigo bush - grows from 3 m to 5 m tall as a glandular, thornless shrub, with leaves made up of many hairy, oval-shaped, spine-tipped leaflets. The inflorescence is a spike-shaped raceme of many flowers and the fruit is a legume pod containing one or two seeds. It is a very hardy plant that can grow on all types of soil. The species is considered a rare species in some US states or Canadian provinces, but is considered an invasive plant in some other areas. Many cultivars are available, like 'Albiflora', with white flowers, 'Crispa', with curled leaves, or 'Pendula', with arching branches, forming a dome shape.

Plant my false indigo

Plant preferably between September and the end of November or between March and the end of April, when the winter reserves are formed and the temperatures are not too low. Bury the roots a few centimeters so that the foliage is flush. Fill and pack well around the plant so as not to leave a pocket of air. Water copiously just after planting. If you are planting in a pot, use one whose volume corresponds to that of the plant, otherwise you will have to water it too often. You can use gravel at the bottom under mixture of soil, compost or compost for better drainage.

Water my false indigo

Water regularly in the first weeks. Try to avoid watering on sunny afternoons to minimize the amount of moisture lost to evaporation. If your plant is in a pot, check the top soil in the pot either by looking at it or touching it with your finger. In any case, if it hasn’t rained in a month, water !
