It looks like it is prematurely fading and skipping the famous pinks. Usually it does this over here when the Summer sun and temps are way too hot. Or when it is getting insufficient water in the Summer months and aborts the blooms.

Where are you located and what is your USDA Zone? How has your weather been the last 2-3 weeks like? When did it begin blooming (white) for you? And when did it start turning green?

If someone asks, just say it is Limelight! Hee hee hee!

Yes, it been so hot and dry here in the Chicago area (zone 6) in the past few weeks. I been so busy that I didn't get a chance to water my garden often enough. I planted in the partial shade area under the maple tree. It gets full sun in the morning and shade in the afternoon. It blooms beautifully every year. This year, it just decided to skip the pink. Now that I know, I will take care of it better next year.

Agree with Luis: I think it's the heat/lack of water. That is what happened to my young VS last year: I was afraid of overwatering and ended up not watering enough during summer heatwaves, and the blooms went from white to greenish to brown and skipped the pink almost entirely.

Oh, nice. Looks A-OK to me! :o)

Thanks all. I will take better care of it next year. Should I cut off the flower this Fall or wait till Spring?

I generally keep the flowers until I 'do not like them'. If the blooms are still "ok" blooms to your taste -although they are green/white/brown/etc-, enjoy them this way but deadhead them once you change your mind. Some people leave the browned out blooms thru winter but that is not necessary.

Mine turned brown instead of pink. Also green. Sun was way too hot on them. I watered daily Too.

I watered regularly and my have bloomed beautifully, but they are white for the first time in 4 years. Is it the ph balance of the soil?

Paniculatas normally produce white blooms and the blooms are not influenced by the soil pH. They then turn whatever shade of pink they are supposed to. However, high temps and-or soil moisture problems will prematurely brown out the blooms. So lower temps, specially cooler overnight temps will help.

How much is to much water? My hydrangeas starts out in shade but as sun lowers in sky in late summer it is in full sun! Went from white to brown????

You should use enough water to get the soil moist down to a depth of around 8". If you water the plant, wait a while for the water to drain and then feel that the soil is still dry at a depth of 8", you did not use enough water.

On the other hand, if you test the soil and it feels wet or soggy then you used too much water. Another test: put some soil in between two fingers and press: if you see water droplets forming, you may be over-watering.

If the blooms are prematurely going brown, the plant is heat stressed: temperatures are too high, the soil lacks enough moisture, it is too windy, it gets too much sunlight or the plant is too young and has a limited/small root system. If young, it may perform better in future years. In my extreme summers with nearly 100F daily temperatures, the blooms turn brown early.

VS was developed in Gorron, a town in Mayenne, France with mild winters and mild summers. That is in the NW corner of the country; close to the English Channel and Great Britain.
