To maintain that life, we’d like biodiversity. This implies not solely rising a various collection of native vegetation however guaranteeing every plant species additionally presents genetic variety.
Because of this rising from seed, or shopping for native vegetation grown from seed, is helpful. Sexual copy makes every seed one-of-a-kind—one thing you don’t get from cloning (rising from cuttings). It’s that genetic variety that brings resilience and adaptableness in difficult situations.
