Life cycleThe life of the Jacob's Ladder 'Blue Pearl' begins with seed germination, typically when temperatures are cool in spring or fall. Following germination, it enters the seedling stage, where it develops its first true leaves and begins to establish a root system. As it grows, the plant enters the vegetative stage, where it develops a clump of fern-like foliage and strengthens its root structure. When mature enough, usually in late spring to early summer, it enters the flowering stage, producing clusters of bell-shaped, blue to violet flowers attractive to pollinators. After flowering, it sets seed, allowing for dispersal and new plant growth. Eventually, as temperatures cool in late fall, it enters dormancy, with above-ground growth dying back, and it survives as underground roots until the next growing season.

Spring-Early Summer
The most popular way to propagate the Jacob's Ladder 'Blue Pearl' variety is by division. Typically, the best time for division is in the spring, just as the plant begins to show signs of new growth. To divide Jacob's Ladder, carefully dig up the plant, ensuring you get as much of the root system as possible. Gently separate the plant into smaller clumps, making sure that each section has a portion of roots attached. Replant the divisions immediately at the same soil depth they were originally growing, spacing them about 12 to 18 inches (approximately 30 to 45 centimeters) apart to allow enough room for growth. Water the newly planted divisions thoroughly to help establish them. This method of propagation is quite straightforward and helps to rejuvenate older clumps that may have become too large or crowded.
