(St. Peter’s Palm)
Originating from Mexico
A multi-branched tree from Mexico with spherical heads of rigid, olive green leaves bearing curled, thread-like filaments along its margins, terminating in a sharp spine. In the wild, it can become a spectacular and imposing feature on the landscape reaching 12m in height with numerous branching heads, although unlikely to reach such grand proportions in the UK.
Grow in sharply drained soil in full sun.
Height and spread after 4 – 5 years 80cm x 60cm
Semi mature height and spread after 10 – 11 years 2m x 60cm
Potential height and spread after 25 years 4 – 5m x 2m, width is dependent on flowering and subsequent branching.
