What we can learn from Eastern Redbud trees

My Brooklyn neighborhood is in full bloom with flowering trees putting on a colorful show for all of us. One of the trees that always catches my eyes this time of year is the Eastern Redbud. They grow bright pink, purple, and red buds directly from their trunks. Known as cauliflory and found mostly in the tropics in species such as cacao, jackfruit, and papaya, the evolutionary purpose of this adaptation has a few hypotheses.

1.) Foster as many partnerships as possible
With the ability to grow flowers on the trunk, the Eastern Redbud can produce more flowers, allowing for more seed dispersal and pollination opportunities. Additionally, more animals can act as pollinators. For example, small mammals climbing onto the tree trunks wouldn’t normally play a role in pollination when the flowers are on delicate branches that cannot support the weight of these mammals. However, with flowers growing on the main trunk that can support them, they act as pollinators for the redbuds just as much as birds and small insects.

For us, emulating a redbud means considering all of the potential partnerships we have around us. How can we change what we’re doing to help them help us? Even if someone doesn’t normally play a certain role, could they fill that role if we altered the system in a way that allows them to participate?

2.) Energy and resource savings
Without the need to grow a network on many delicate branches, flowering directly on the trunk saves the tree energy, water, and food. These resources can be poured into creating more flowers and therefore greater pollination and seed dispersal. The redbud certainly takes advantage of this, and in full bloom appears to explode with flowers.

There is nothing worse in nature than waste. Wasted energy can and often does mean the difference between life and death. Are we using all the resources we have in the most optimal way? Can we change how we operate to make better use of the resources we have to meet our ends goals?

3.) A matter of physics
In the case of trees such as cacao, jackfruit, and papaya, the fruit is too heavy for small delicate branches to bear. The weight of the fruit requires a sturdier structure so they grow directly from the trunk. This also allows the fruit to grow to a larger side, and again, allows for greater seed dispersal.

Sometimes we’re forced to do things a certain way for the sake of practicality and to best meet our end goal. Necessity may be the mother of invention, but practicality is the agent of adaptation, moving us along to do exactly what needs to be done.
