Agave multifilifera

Agave multifilifera is a truly unique species with foliage that sets it apart. Its long and narrow stiff leaves are adorned with multiple curly white filaments along their edges. The numerous leaves spread out in all directions, forming a perfectly hemispherical rosette. The plant grows slowly to reach a diameter of 1m and develops a trunk up to 50cm high, resembling some Yuccas or even a Dasylirion. Its architectural silhouette and resistance to heat and drought make it highly sought after in dry gardens with a milder climate, as it is hardy only to around -10°C. In colder regions, this Agave should be planted in a large pot so it can be brought indoors for protection during winter.

Agaves, formerly classified in the Agavaceae family, are now part of the Asparagaceae family, which has absorbed several former botanical families and takes its name from asparagus (Asparagus in Latin). The Agave genus includes numerous species, ranging from 190 to several hundred depending on the authors, native to the southern United States, Mexico, Central America, and South America. Many species are used for ornamental purposes, and some have culinary value (agave syrup, tequila, mescal...).

Agave multifilifera, also known as the Disheveled Agave or Mountain Agave, is native to northern Mexico. It can be found in the states of Sonora, Chihuahua, Durango, and Sinaloa, growing between 1400 and 2100m on rocky slopes and cliffs, in pine or oak forests. The species is characterised by its very narrow and elongated, delicately streaked, flat and not very fleshy, medium green leaves, sometimes tinged with yellow-green. Measuring up to 80cm in length with a width of only 2 to 3cm at the base, these leaves are not toothed but have a green, then grey, terminal spine. They bear curly white filaments along their edges and form a perfectly shaped, hemispherical, very sculptural rosette. It is one of the Agave species with the most leaves, sometimes exceeding two hundred! The plant grows slowly to resemble a young Yucca filifera. Unlike many of its relatives, this species does not produce offsets and eventually forms a short trunk up to 50cm. A mature specimen can reach 1.50m high with a rosette diameter of 1m. After 20 or 25 years, it will possibly produce a spectacular flowering stalk, reaching a height of 4 or 5m. The flowering period extends from June to August and marks the death of the main rosette, which is replaced by a few axillary shoots.

This Agave is perfectly adapted to Mediterranean climatic conditions, especially long, hot, and dry summers, and with its architectural silhouette, it will be perfect in a rock garden or a bed in a contemporary garden. It will happily coexist with Opuntia plants, those prickly pear cacti with shapes that evoke desert landscapes. A specimen of Cylindropuntia tunicata with elongated stems that have not transformed into pads will add variety to your bed. This compact and spreading cactus is highly ornamental with its countless white spines, and like Opuntias, it will also reward you with a short-lived but stunning flowering. To add a touch of blue, plant a specimen of Yucca rostrata 'Sapphire Skies', which will form a perfectly round ball of irresistible steel blue. Hesperaloe parvifolia, also known as Red Yucca (although it is not a Yucca), will produce a lovely clump of slender leaves bordered by twisted filaments, similar to the Agave multifilifera, and particularly stunning coral-red flower spikes throughout the summer.
