Basil is a delightful herb. It likes to stretch out green under a hot sun with its sweet aromatic fragrance permeating the air. It is a native of Southeast Asia and sacred to the Hindu religion. It’s even considered an Elixir of Life by some.

Basil leaves are a delicious edible herb – but not its flowers. When the flowers arrive, remove them, or they’ll take the plant’s strength, thus inhibiting the growth of leaves. If the flowers thrive at harvest time, the leaves will not, and you’ll have a small and bitter harvest.

Why Is It Flowering?

When a Basil plant starts flowering, it changes from the growth stage to the reproduction stage. In other words, the plant’s energy goes into flowering rather than growing its leaves.

As part of its growth, when a Basil blooms, the leaves lose their flavor.

Basil is an edible herb that produces flowers. Flowering is part of Basil’s natural life cycle in late summer. However, the flowers are for one purpose – seeding.

They’re harmful to the development of the leaves and, if left to flourish, they can cause a bitter, sour taste to the leaves.

Because Basil is annual, the flowers will produce seeds that can be used to grow new plants in the following spring. Letting them grow eventually will produce purple or white flowers, which look so beautiful.

You’re growing Basil for the delicious and aromatic foliage as these leaves are valuable both in food and healing. However, you can use the flowers for their seeds, which you would plant for the following season.

The Life Cycle Of The Basil Plant. Below Are The Three Stages:

1. Young Or Growing Stage – In this stage, Basil grows about 12 inches long and produces the most amount of leaves.

You could also cut the big leaves on top but leave the smaller ones at the bottom for the plant to grow.

2. Transition Stage – Towards this stage of Basil’s life cycle, the leaves don’t grow and don’t produce more.
