Invasive plants

Posted On: July 12, 2023

The UF/IFAS Extension Volusia County recommends that homeowners and businesses follow Florida Friendly Landscaping principles, which promote the use of low-impact, environmentally friendly, science-based practices that use less water and reduce pollutant loading to Florida waters. 

Extension agents recommend that you avoid using invasive, non-native plants, which do not occur naturally in a particular area. These species have been introduced intentionally or unintentionally by humans. They can also cause harm to the environment, the economy, and even human health.

Take the asparagus fern (Asparagus aethiopicus), for example. Don't be fooled by the pretty, red berries. This highly invasive South African native is BAD, BAD, BAD because it displaces Florida native plants and prevents them from establishing. Asparagus fern spreads by bird-dispersed seeds and its tubers, or roots, which sprout far from the main plant. Once established, it's difficult to control. What's more, this common ornamental is not a true fern. Learn more at https://tinyurl.com/6s69yb7n. 

The popular coontie (Zamia floridana) is a great replacement for the asparagus fern. It's a wildlife attractant, providing good low-ground covering for birds and small mammals, and it's a preferred food source for larvae of the echo moth (Seirarctia echo). Coontie thrives in drier soil conditions and is tolerant of drought, cold and salt. In fact, its native habitats include all areas of the Ormond Scenic Loop & Trail. Learn more at https://tinyurl.com/2p72vt4r.
