Agave xylonacantha (a.k.a. Saw leaf agave) has very wavy and toothed leaf and is a standout. The margins of the leaves have broad, flat, papery spines that are arranged in an irregular fashion, making the leaves look like old fashioned wood saw blades.
Agave americana 'Mediopicta Alba' is one of the prettiest and most sought after variegated succulents in existence. It is a living sculpture with very dramatic creamy white bands down the centre of the blue leaves.
The cultivar Shoji-Raijin (sometime called the ’Silver Star’ or 'Blue rose') is an irresistible collector's plant that is simple to grow; it stays compact (only 5-7cm tall) and makes a great looking plant with dusty blue leaves.
What a beauty of a miniature Agave! It is among the most ornamental species, vying with A. victoria-reginae in the exquisite regularity of its form. The young plants are quite different from the adults, but are however very lovely too.
