Manfreda maculosa (Texas tuberose)
An unusually attractive foliage plant with mottled leaves, Manfreda maculosa Texas Tuberose also known as rattlesnake agave is a great choice for rock gardens. It can take full sun to partial shade with a well drained soil mix. Needs very less water. Plants are watered only enough to keep the foliage from shriveling.
Agave geminiflora (Twin Flower Agave)
A dramatic plant which blooms yellow flowers with a hint of red. This Mexican native is a natural for the desert garden or the modern architectural landscape. The symmetrical, nearly stem less rosette, smaller size, fine texture, and resistance to pests make this a first class landscape plant. It thrives in full sun, even in low desert, but will do equally well in shade. Adequate water ensures a dense symmetrical form and optimal colour. Whether in modernistic or naturalistic landscapes, few plants rival its uniformity of size and widespread adaptability.
Alcantarea imperialis rubra
Formerly known as Vriesa imperialis, this dark-red giant can span over 1.5 meters in ten years. The tough, leathery leaves tinge a deep red in bright light. The thick, red flower spike can grow 2.5 meters high, producing hundreds of lightly fragrant, white flowers. Prefers bright light and can withstand relatively cool temperatures.
