About Panicle Hydrangea 'Vanilla Strawberry'
Hydrangea paniculata 'Renhy' · also called Vanilla Strawberry Hydrangea · flowering
'Vanilla Strawberry' is a panicle hydrangea whose large conical blooms open creamy white, then age through soft pink to deep strawberry-red, often showing all three shades at once. A tough, sun-loving deciduous shrub flowering on new wood, it is far hardier and more sun-tolerant than mopheads and blooms reliably every year.
Plant type: flowering
Watch for — Weak colour in shade: The pink-to-red aging needs sun; in too much shade blooms stay pale and the show is muted. Grow in full to part sun.
The reasons panicle hydrangea 'vanilla strawberry' isn't blooming
Almost every non-blooming panicle hydrangea 'vanilla strawberry' traces back to one of these, roughly in order of how common they are:
- Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
- Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
- The plant has not been deadheaded, so it stops flowering once it sets seed.
- Irregular watering — drought or waterlogging at the budding stage makes buds abort.
- It is still too young or was checked by a transplant and is rebuilding before flowering.
Feeding panicle hydrangea 'vanilla strawberry' a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.
The fix — how to get panicle hydrangea 'vanilla strawberry' to flower
- Maximise sun. Give panicle hydrangea 'vanilla strawberry' the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
- Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
- Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
- Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.
