Solidago gigantea - the goldenrod - is a North American - but widespread - species in the sunflower family known from most of non-arctic North America east of the Rocky Mountains. An herb up to 200 cm (80 inches) tall, sometimes spreading by means of underground rhizomes, often growing in clumps with no leaves as the base but numerous leaves on the stem. At the top, each stem produces a sizable array of many small flower yellow heads, sometimes several hundred.

Plant my goldenrod

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 goldenrod

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 !
