How old is it?

You may not need to replace it.

Ok.

You have it in part shade which is good and its grown fine which good.

Not getting a good color change is a common problem for VS.

I'm in zone 5 and it took 5 years before I got a color change (before that white to brown like yours)

Thus you could try the following.

1. Give it more time

2. Don't fertilize, paniculatas don't really need it, and you don't want to accelerate blooming.

3. Apply straw mulch at the base. Keeping even moisture seems to be a key factor in color change.

4. Delay pruning. Paniculatas grow on new wood and typically pruned end winter early spring, but you could delay pruning several weeks which will cause it to bloom later in the season.

If you decide you definitely want to scrap it I'm not sure that there are paniculatas which bloom later, but with my limelights I didn't have the browning issue like I did with VS.

Also i'm sure some people here who are around your zone could give you other recommendations about other varieties based on their growing experience.

Thanks! I guess I will give it another year and in the meantime get a limelight and plant it elsewhere.... Funny you should mention pruning; one year I waited till I saw the flower buds in June and pruned them all off... I didn't get ANY flowers that year, LOL.

since they grow on new wood of course if you wait too long you won't get any flowers. That's why I suggested delaying just a few weeks to start and then you can adjust from there in the subsequent season depending on the results.

For example, try pruning mid April see what happens and go from there the subsequent season.

If you decide to do that let us know how it goes.

Tardiva is the "latest" blooming paniculata if you still are asking.

VS also likes more shade than the average paniculata. It will do better, if you can get it into half-shade (like no more than 6 hours sun). Thanks and have a great day!

Thank you guyground, luis, and springwood... I will try tip pruning a little earlier next year... I am glad to know about Tardiva being a late bloomer.... My VS gets about 3 hours of sun, which is probably like getting 4 or 5 hours in a zone 6.. Anyway, it's enough to produce lots of blooms which look good for about 2 weeks before starting to get brown. But maybe not next year!

With some more time (2-3 years) or next season hopefully your VS will be just fine.

Lois try watering more, not sure how much rain you get where you live. Seems to really help the blooms stay nice, as well as letting them mature a little more. we aren't as hot and sunny here, but mine are in full sun all day and I notice some extra water really prolongs the bloom time. Good luck, they really are a pretty shrub :)

How large is yours ? Any pictures ?
