Water regularly until established, then reduce to occasional watering as needed. Once mature, Thryallis is quite drought tolerant — avoid overwatering which can cause root issues.
Full sun lover — needs at least 6 hours of direct sunlight daily for the most abundant blooms. In shady spots it will grow leggy and produce far fewer flowers.
Grows 4–6 ft. tall and 3–4 ft. wide — upright, airy, and perfectly sized for borders, hedges, and garden accents.
Plant in well-draining soil in a sunny spot and water regularly until established. Feed with a balanced fertilizer in spring and summer to keep blooms coming strong. Prune lightly after each bloom cycle to maintain a neat, full shape and prevent legginess. Its delicate yellow flowers and sweet light fragrance make it a beautiful addition along walkways, borders, or as a colorful complement to taller privacy hedges.
Pair Thryallis with purple-flowering shrubs for a stunning golden and purple color combination that lights up any sunny landscape all season long.
Plant Thryallis along a sunny walkway or garden border for a cheerful, golden display of star-shaped flowers that blooms almost year-round.
