Birthday Cake™ Butterfly Bush

Birthday Cake® is an upright hybrid butterfly bush with fragrant pink-purple flower spikes that rise above the foliage like candles. Bloomin’ Easy lists it at 4–5 feet tall and 2–3 feet wide, with summer-to-fall flowering in full sun. Its cultivar code, PODARASNGA 3-30, matches the live catalog record. ## Form and placement The upright habit and narrow spread suit the middle or back of a sunny mixed border, where the tall flower stems can be seen. The breeder lists zones 5–9, a 3-foot spacing, and describes the selection as compact and pollinator friendly. Its height differs from dwarf Pugster and Lo & Behold selections, so avoid treating all butterfly bushes as the same size. ## Growing conditions Plant in full sun and well-drained soil. Water thoroughly during establishment and adjust irrigation for local rainfall and soil; do not infer low water needs from heat tolerance. Flowers are fragrant and held upright through summer and fall. Hardiness claims are breeder guidance and can vary with winter drainage, exposure, and local conditions.

Remove damaged stems after winter and prune as needed to maintain the upright shape. The source does not specify a pruning schedule, so avoid hard annual pruning by default until local growth and flowering response are observed.
