The pods on my esperanza are brown. Does this mean it's time to harvest? Best time to plant seeds?

Context Explanation

What is germination rate? Same question for Orange Esperanza. Thank you much. Post #2559561 Quote crowellli Houston, TX (Zone 9a) Planted in full sun, my esperanza blooms profusely pretty much year round with luscious yellow clusters and graceful arching branches.

Insight Material

After it blooms seedpods (that look like string beans) appear on tips of branches where the flowers were.
