Definition - What does Strap Leaf mean?
In botany, strap leaves refer to leaves whose margins are entirely or partially missing, hence giving the leaf a much narrower structure than usual.
Strappy leafed plants resemble grasses, but they are not grasses, despite having a similar growth pattern.
Strap leaves are long green blades or straps that may be thin, thick, or fleshy. A strap leaf plant doesn't usually have a stem, rather, their leaves all stem from a central point.
MaximumYield explains Strap Leaf
Most strap-leaved plants and grasses are quite tolerant to dry climates and droughts. When growing strap-leaved plants, it is important to ensure that the soil is well-drained. This is why mulching has also been known to help the plants easily withstand harsher weather conditions.
Additionally, because they are lighter and more delicate than thicker leaves, strap leaves need to be sheltered from direct sunlight. They also need partial shade in order to thrive and develop.
Vanda orchids, for example, require at least 80 per cent humidity because of their strap leaves. To create sufficient humidity for the plants to thrive, some gardeners either place a humidifier near the plant or spritz the air around the orchid several times per day.
In contrast, cladiums, another plant know for their strap leaves, require quite a bit of care and maintenance during rainy seasons. Thus, strap-leaved plants aren't all created equal.
