|This plant didn't bloom for two years. Clearly it's doing fine now, but why?|
My parents decided to bump out the living room wall and put in a large bay window a couple years ago, requiring many plants to be relocated. Bumping out the wall reduced the depth of the bed by over a foot, but the space under the eve, which was uniform across the roof rather than following the recessed wall, wasn't really usable anyway.
The majority of the plants that needed to move were transplanted to the south end of the house, including the Yucca filamentosa I've shown previously, several echinacea, some inherited orange lilies and gladiolus, and two of the kniphofias. The following summer, the two kniphofias that were moved bloomed! And not just a few stalks, but a full show. Clearly they had been large enough to bloom for some time. I assumed that they were responding to the longer duration of full sun they were exposed to on the south end of the house and determined to move the remaining two as well.
|A bit past its prime, this was one of the first two kniphofias to be relocated. It bloomed just as well last year the summer after it was moved.|
|The second of the first pair moved, the same as the one in the topmost picture. This one is darker, blooms a bit later, and lasts longer, but didn't produce as many blooms at once this year.|
This spring, I started work on the bed along the west side of the house, moving the plants that hadn't been moved prior to construction, amending the soil, and raising the soil level as well as sloping it away from the house to improve display and drainage. One of the two kniphofias in this bed was moved to the southwest corner of the house with the two that had been moved previously. The other I replanted in the bed along the west side of the house, wanting to know if it would bloom after simply being moved. I wanted to know if it was the greater sun exposure or the move that had triggered bloom.
|One of the two kniphofia remaining in the western bed. It turned out to be the darkest of the bunch.|
|The dark orange above matures to a much lighter orange fading to yellow at the bottom.|
|Searching for blooms on the fourth plant, I found this!|
