Sepals are the green “ foundations ” of most flush . They provide protection while the buds are developing and then volunteer morphological support for the petals once they educate and open up .
When Tomato Big Bud come into play , those sepals can acquire up to 10 times their normal size : far large than the efflorescence they encase .
What bechance next is that instead of protecting the buds until they open up , the sepals fuse together and do n’t spread to unfreeze the flower bud inside . In fact , they might actually develop foreign shoot and grow even larger !
to boot , plant afflict with Tomato Big Bud will prepare numerous side shoots and branch from their stems so they become shaggy-coated , rather than tall .
