SMALLER IS SOMETIMES BETTER!
In anticipation of hurricane season, many will begin their tree trimming practices to minimize potential hazards and tree failure due to structural defects on large canopy and street trees such as oaks, mahogany, gumbo limbo and others. Sometimes, planners and landscaping companies forget that South Florida has a plethora of small to medium native trees that can be useful in many situations, provide a host of benefits and best of all, require less maintenance.
Let’s take a look at some of the benefits of smaller native trees:
- Turf and other plants can grow beneath and around them due to narrower canopies. In many situations, where turf or flowering plants are desired or required, large trees can cause them to struggle due to their shade and competition. Turf will be less stressed and healthier with more sunlight.
Orchids, such as this Oncidium, grow well on smaller trees because of more light, and smaller native trees provide branching at just the right height for viewing.
- Many of the smaller trees will provide habitat and food for birds, butterflies and other beneficial insects, which help to mitigate and control the insects that cause problems.
- Smaller trees are easer to prune and maintain to ANSI standards.
- Smaller trees are less likely to cause damage during storms.
- Many of these trees have colorful flowers and/or foliage.
- Our native trees require less fertilizer and pesticide due to their acclimation to our climate, soil and rainfall conditions.
- These smaller trees add much needed biodiversity and interest to a stagnant palette.
Why is the palette so limited?
Because landscape architects, city planners and others often get to make the decisions regarding the species of trees planted, our plant palettes become limited. Many of these folks aren’t horticulturists or growers and don’t have the knowledge or familiarity of the vast plant palette available in South Florida.
A sampling of some great under-utilized native trees:
Here is a list of some worthy candidates where you may need a tree in a tighter space, parking lot, between homes, or in many situations where a large canopy tree is inappropriate and can become a liability. Some may be difficult to source, but remember, if growers have more demand, they will grow more of them. FANN or Florida Association of Native Nurseries, can help you to source them.
Bahama Strongbark (Bourreria succulenta) –upright, umbrella like growth, fragrant white blooms/red fruit year-round, attract hummingbirds and butterflies H20 X W8

A smaller carbon footprint
Most importantly, using smaller, native trees will establish beauty and variety in our landscapes while also providing sustainability and preservation of our natural resources. Smaller is often, better!
