What's wrong with 'Siskiyou pink' gaura?

bostedo(8a tx-bp-dfw)March 27, 2014

This 'Siskiyou pink' is behaving very differently than our white gaura cultivars and am trying to figure out what is going on. Purchased in a 4" pot from a reliable Austin nursery last summer. It immediately shot up a two foot+ hard wooden stem from which it flowered... it was a monster. Figured soil may have been too rich in that spot, so transplanted it to unimproved space in the alley and was already able to pot a couple small divisions. It flowered fine until the first freeze, but never developed a rosette like our other gauras. Both divisions grew the same way with a single firm stem; one of which I kept alive indoors over the winter. The mother plant and division left outdoors are showing no signs of life, so believe they froze to death without a sustaining rosette. Anyone know if there is a trick to getting the remaining division to grow "normally"? TIA

I'm so sorry you lost the mother plant. I know the feeling. Did you try grouping them together? Just wondering if you watched the PBS Nature segment on how plants talk to each other? It was amazing! I think we clearly under-estimate plants. I've never seen a program so fascinating.

Sunnysa, This is pretty amazing stuff. Had seen it OTA before and appreciate the link for another look.

Didn't group them, but am guessing the problem is related to propagation. After thinking it over, seems more likely that I had three cuttings started in the original pot rather than a mother and two divisions. The leaves and panicles on each all grow off of a single woody stem (original cutting?) rather than out of the typical rosette. Maybe layering the survivor could fix this?
