What makes Rosenka special is its color-shifting bracts — they open golden-orange and gradually fade to salmon-pink as they mature, giving you multiple warm colors on one plant at the same time. This bush form grows naturally as a full, mounding shrub that's perfect for borders, foundation plantings, and containers. It handles full Arizona sun, thrives in reflected heat, and blooms heaviest when other plants are wilting. Whether you're adding color to a Scottsdale desert garden, filling a border in Mesa, or creating a container accent in Chandler — Rosenka Bougainvillea delivers nonstop, multi-toned blooms with minimal care.\u003c\/p\u003e\n\n\u003ch2\u003eBougainvillea 'Rosenka' Plant Details\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eBougainvillea 'Rosenka'\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Names\u003c\/td\u003e\n\u003ctd\u003eRosenka Bougainvillea, Color-Changing Bougainvillea\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMature Height\u003c\/td\u003e\n\u003ctd\u003e4–8 feet (bush form)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMature Width\u003c\/td\u003e\n\u003ctd\u003e4–8 feet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrowth Rate\u003c\/td\u003e\n\u003ctd\u003eFast — 2–4 feet per year in Phoenix\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSun\u003c\/td\u003e\n\u003ctd\u003eFull sun (6+ hrs).

Warm soil and rising temperatures trigger rapid growth. Your plant gets a full growing season to establish before winter. Fall (October–November) works but provides less time before cooler weather. Avoid winter planting — bougainvillea is frost-sensitive and cold soil stalls root development.\u003c\/p\u003e\n\n\u003ch2\u003eHow to Plant Bougainvillea 'Rosenka'\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eDig wide, not deep\u003c\/strong\u003e — 2–3x the width of the root ball and the same depth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCheck for caliche\u003c\/strong\u003e — Break through hardpan for drainage.

Month 1–3: Every 4–5 days. Month 3–6: Every 7–10 days. After Year 1: Every 10–14 days in summer; every 3–4 weeks in winter. Let soil dry between waterings — overwatering produces green growth but fewer blooms.\u003c\/p\u003e\n\n\u003ch3\u003eDrip Irrigation\u003c\/h3\u003e\n\u003cp\u003ePlace two 2-GPH emitters 18–24 inches from the trunk.

New bracts open golden-orange and shift to salmon-pink as they age, giving you a beautiful gradient of warm colors on the same plant. No other bougainvillea variety does this.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between the bush and staked form?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe bush form grows as a natural mounding shrub — great for borders, containers, and foundation plantings.

In most Phoenix Valley locations, hard freezes are rare. Cover with frost cloth if temps drop below freezing.
