Why Is My Flaming Trumpet Creeper Having Pale Yellowish And White Blooms Instead Of Fiery Orange Ones?

Question

I bought a Flaming trumpet creeper almost a year ago which has recently had a couple of blooms. I planted it directly into the soil. It was shown in the website that it has brigh orange coloured flowers but my blooms have been somewhat of a pale yellow almost white type of colour. I have checked online and there doesn’t seem to be any colour variation of this creeper. So why is the colour so different?

Answer 1

There are certain cultivars that match this color and structure. Campsis radicans 'Flava' is the most common that comes to mind. It is very possible that it had dropped seeds, already, and they were a cross with the yellow lineage. This can show through.

Less common is reversion. Reverting back to one genetic set or another is possible, but this is pretty rare.
