Agave gentryi is a wonderful variety originating in North Eastern Mexico where it can be found on mountain slopes. Beautiful reddish spines run along each leaf with a strong similarly coloured terminal spine. The overall colour too is impressive, a deep almost glossy blue-grey green. Each plant reaches a height and diameter of around 120cm or more Agave gentyri is an imposing plant requiring careful siting in the garden. Agave gentryi carries the same attributes as it’s wild cousins meaning it is tolerant of more moisture and cold than many agaves and as such is a candidate for out cultivation here in the U.K.
As with all Agave worth growing outside in the U.K unless you have a very mild or dry micro-climate I always recommend building a roof over the top of treasured agave plants in winter. Simply hammer in 4 stakes around the agave a fix a clear plastic ‘roof’ onto the top of each stake above the agave leaving the sides clear allowing wind to pass through the leaves. Alternately we recommend growing in a pot in full sun from April to the end of October depending on the weather and moving it to a greenhouse, conservatory or even shed for the winter where it can have protection from freezing and wet. No watering will be needed from November to March.
