Low Chill Lilacs


The lilacs are blooming in the local park where this nursery was once located. No labels exist on the bushes. How do we know what they are?

Checking in some old catalogs, I found this:

"Our efforts in behalf of Lilacs may be attributed to the splendid work of Mr. W.B. Clarke of San Jose, noted hybridizer of spring flowering shrubs and trees. It was he who developed the three excellent varieties pictured above."

I had thought that Descanso Garden was the place where low chill lilacs originated, but apparently it was in San Jose! And Descanso carried on.

Clarke had spent over 20 years selecting and re-selecting lilac strains that offered good blooming promise under mild winter conditions. Dr. Lammert's work, in turn, was just beginning. Back to UCLA, where he grew the seeds, then over to Descanso Gardens at La, Canada where they were matured and observed, and finally all but a few were discarded.
  • Independent Journal, June 13, 1953, "One man responsible for many of our popular newer plants is W. B. Clarke of San Jose. He, for example, brought back to our gardens the much desired “yesterday, today and tomorrow" plant. This fragrant shrub out of Brazil had been in California gardens back in the 80s. In 1928 Clarke found it in an old Menlo Park garden. He propagated it, offered it to the trade again, and immediately amateurs everywhere, in Ukiah, to San Diego rushed it into the garden. "
