Agave salmiana ss. Salmiana are native to central and southern Mexico. A superb, evergreen, architectural plant that forms a large rosette of wide, dark green to grey green leaves. An outstanding and dramatic plant for drier, warmer temperate regions. Will tolerate frost to around -5c as long as the soil is not saturated. Will not tolerate waterlogged soil but are very drought resistant. Grow in full sun. These plants are unpredictable in terms of flower production, however some time from around 25 years old the plant will produce a very tall, single flower stem, with multiple corymbs of dark yellow flowers. When the flower dies, so does the whole plant however by then there will have been many offshoots so more plants will be on their way. This plant can be used in a mixed planting, as a stand alone specimen in the garden or a container. If planting in a pot or other container. Use a good quality, John Innes compost as this plant will be there a long time and peaty types of compost eventually degrade and become too packed and choke the roots. Add a minimum of 20% horticultural grit by volume, to aid drainage. Ensure you feed regularly as a hungry plant is a poor performer. We recommend Osmoscote pro 8-9 month applied in the early spring. One application gives all the nutrients the plant requires for the whole year. John Innes is a soils based compost. Because these are drought resistant plants some gardeners take this to mean they can be given very little water, which is true, however these plants grow fastest and look their best when grown in fertile, constantly moist soil, during the growing season.
