About Mexican Grass Tree
Mexican grass tree (Dasylirion quadrangulatum) is a dramatic slow-growing succulent from Mexico, forming a fountain of long, slender, unarmed grass-like leaves on a gradually developing woody trunk. Hardy to 15°F, it suits NE Florida's zone 9b in hot, dry, well-drained sites; flower spikes can reach 15–20 feet when mature. Excellent drainage is essential in Florida's humid climate. Starting at $59.95.

Care essentials
Mexican grass tree requires full sun; it performs best with 6–8+ hours of direct daily light. In NE Florida, site it in the hottest, sunniest spot available and ensure the planting area is elevated for drainage — crown rot in humid conditions is the primary risk.
Water once or twice a month once established; Mexican grass tree is highly drought-tolerant. In NE Florida's rainy season, excellent drainage is critical — standing water around the crown causes fatal fungal rot. Do not irrigate the crown.
Plant in sandy or rocky, sharply draining soil and position above grade to prevent water accumulation. NE Florida's sandy soils are suitable; amend clay sites with coarse sand and gravel. Fertilize lightly twice a year; overfeeding is unnecessary and can promote soft, rot-prone growth.
