Eve's Necklace occupies a distinct niche in the southern garden: a limestone-loving, multi-trunked small tree that performs best where most ornamentals struggle. Native to creek banks, open meadows, and rocky pastures of the south-central United States, it brings the look of wisteria to zones 7 through 9 without wisteria's aggressive spread. Rose-pink fragrant clusters appear in spring, followed by the dramatic beaded pods that give the tree its name and persist through winter as a structural ornament. In full sun, plants stay compact and flower most freely; in shadier spots they stretch toward 35 feet and bloom more sparingly.

Give it sharp drainage above all else. Chlorosis will set in quickly on poorly drained ground, and the tree sulks in waterlogged soil even briefly. Once established, it shrugs off summer heat and drought with ease, making it well suited to the Texas Hill Country and similar climates. The low-branching habit means pedestrian paths will need occasional clearance pruning, but in open lawn or border settings that natural spread reads as character. A note of caution: seeds and flowers are toxic if ingested, so site with care around children and pets.
