Dasylirion serratifolium is an extraordinary member of the Asparagus family. It’s bold, dramatic and architectural with long, narrow strap-like leaves which are covered with tiny spines along both sides giving a serrated, jagged appearance. The glaucous green-blue leaves are arranged in a neat, upright rosette and as the plant matures it develops a stout trunk.
The leaf tips are pale and split slightly at the ends and form a tassle-like appearance. Dasylirion serratifolium has bags of character. It may be grown in a container to great effect or planted in very free-draining soil or gravel beds. It is a particularly useful specimen in coastal gardens where it will stand up to the wind and salt. Also provide a hot sunny position where your Dasylirion can thrive and allow enough space for it to perform to its full potential – they are capable of reaching 1.5m in height and spread. In cooler and frost-prone gardens you may need to provide a bit of winter protection or grow in a container to enable moving to a warmer spot for the cold months.
I’m yet to mention the flower – which is outrageous. It starts a little like a fat tip of asparagus and then continues to shoot upwards….when you think it can’t get any taller – it most certainly does. Reaching in excess of 15 feet, the flower spikes are adorned with tiny, fuzzy yellow flowers which turn to maroon-brown.
We recommend regular feeding through the growing season – particularly if a flower spike forms.
Older/lower leaves may be clipped off at the base – wear gloves whilst performing this operation!
So there we have it – the fabulous Dasylirion serratifolium – a must have.
