Weedy Zauschneria

Kim LadinJuly 8, 2013

I planted two California Fuschias last fall in a raised bed, and they've grown like weeds and taken over practically the entire bed. Both plants have grown to 5-6 times their original size, but they've never flowered and don't seem to be planning to.

They get a reasonable amount of water, but nothing extravagant. They did get planted in a bed with very rich soil. Could this be the problem?

Any suggestions on what to do? How does one prune these things? If my soil is too rich, should I just pull them out and put something else there?

Thanks for any advice!

I don't know about the soil, but I cut mine back to the ground after the bloom at the beginning of fall. Mine are blooming now; they just started, though. I am coastal, if that helps.

Mine was very leggy and the bloom was stingy. Maybe that's how they are.

They can be cut back hard, but doing so this late in the year will affect flowering. They can get rangy if given too much water or not enough full sun, and ordinarily would be found in leaner or more gravelly soil conditions.

They are hard to get rid of. The roots go very deep and they grow back from the roots. The hummers like it so I leave it.

Mine receive little water and will stay more compact than others that receive more water. Also, mine bloom more heavily with less water. I'm inland near Fresno, and grow both z. latifolia and a local native variety that I grew from seeds.

It helps to pinch them periodically to encourage branching - most flower heavily and the flowers weigh down the branches. The different cultivars do flower at different times, Bart O'Brien wrote an excellent article on Epilobiums about a trial done at Rancho Santa Ana Botanical Garden.
