Seedling
4-8 weeksSmall plant with thin stems and early compound leaves; very delicate and slow-growing initially
Keep soil slightly moist but not wet; provide bright light; protect from strong winds; use well-draining seed-starting mix
Establishment
3-6 monthsPlant develops stronger stems and more leaflets; begins to establish root system; gradual height and width increase
Water regularly but allow soil to dry somewhat between waterings; begin hardening off before transplanting; light fertilization monthly
Vegetative Growth
6-18 monthsShrub develops woody stems, fuller foliage with feathery compound leaves; plant reaches mature size over 1-2 years
Reduce watering as drought tolerance develops; fertilize sparingly; prune to shape if desired; drought stress actually improves flowering
Flowering
2-4 monthsBright yellow pea-like flowers appear in dense clusters at branch tips; flowers are fragrant and attract pollinators
Maintain minimal supplemental watering; do not over-fertilize; deadhead spent flowers if additional blooms desired; typically occurs spring-summer
Fruiting & Seed Production
3-5 monthsDistinctive segmented bean pods form, resembling a necklace or chain; pods mature from green to brown and contain hard seeds
Allow pods to dry on plant if saving seeds; collect when pods turn brown; seeds have hard seed coat and may need scarification for germination

Harvest Tips
Harvest seed pods in fall when they turn brown and dry on the plant. Collect pods before they fall naturally. Allow pods to cure completely, then crack open to extract seeds. Soak seeds overnight and scarify with sandpaper before planting to improve germination. Flowers can be used for ornamental arrangements when fully open.
