Are the different colored flowers on the same stem or different stems?

Good question. I'll check when I get home :) I think they were from different stems on the plant (I know they were all over it). I'll report back with better details this evening!

OK, looks like the white is showing up on the same stem as others which have already bloomed red. Here are a few photos from this evening (cellphone).

Just in case this isn't clear... the buds that are showing white are on a bunch of different stems, and on some of those stems are there are already-open buds that are red, in addition to the ones that are starting to open white (I think there may even be some where the same blossom looks like it will be BOTH white and red).

My dynamite is throwing off some light pink blooms and my red rockets both have these white blooms mixed in like your dynamite does.

Believe it or not, even us mid-westerners can grow Dynamites (tho as shrubs only, no trees) and yes, it is quite normal for some white blooms to show up here and there, particularly on young nursery plants.

Brian - do those same ones continue to bloom white in subsequent years?

Conditions play a part of whether a little white shows up. Dr. Whitcomb (the guy that introduced this cultivar) reports more white, with cloudier and cooler conditions. Hot, full sun conditions result in more intense, pure cherry red. If yours turns out to have a lot of white or white concentrated on some trunks and not on others, you may a seedling introduced into the clump.

I don't quite follow the last half of your final sentence there, but cloudy and cool conditions are the absolute antithesis of this Spring/Summer for us here - first rain today in MONTHS, and temps averaging about 5-10 degrees above the normally hot summer here anyhow.

It's not all that unusual for a seedling to grow up in a crape myrtle (two plants in one group of trunks). If you have some trunks that produce different flowers than the rest of the plant, one strong possibility is that the varying trunks are actually a separate plant. It may have been like that from the nursery. Another possibility is a mismarked plant, altogether.

Ah... well, only one trunk on these guys so far.

Did they look like this? If so, what happened with the blooming? I bought two red dynamites and one is blooming a pinkish red (very disappointing) that I hope will get a deeper shade of red in the next couple of years. My other one has a lot of partially opened flower buds that are white and kind of in stasis. That is, they have been like this for a week or so. Is this normal? I'm sorry if it is in your pics, they don't show up for me :(

Oh and btw, it has been HOT (hottest June on record here) and sunny the last month and a half to two months.
