The Yucca filamentosa is an excellent shallow soil plant because of the roots habit of growing horizontally. Many times this plant can be seen growing in natural areas with very shallow or rocky soils. Click here for a Floridata plant sheet describing Yucca filamentosa, also know as Adam's Needle.
Yucca filamentosa will grow upright when provided with adequate soil depth. The plant is ideally suited for green roofs because it also possesses the ability to acclimate its habit and height to a more "bonsai" form when limited by shallow or rockier soils.
Another excellent green roof trait the Yucca filamentosa possesses is the low stomata to leaf surface ratio - the S/LSR ratio equation we typically use in green roof plant suitability determinations.
Average soil media depth of the green roof is approximately 1".
The roof is subject to moderate shade, especially on the southern end. Sunlight exposure is greatest between the hours of 10:00 am and 4:00 PM.
After seventeen months in the field the roof is looking good and the plants are well established.
