I have about 15 Leucantheum Becky daisies planted throughout my gardens, all in the full sun. They were extremely healthy and vigorous last summer/fall. What a gorgeous plant! However, not a single one is showing any signs of spring. Not one! Most other perennials are up now, including my endless summer (yey!!). Is it still too early or do you think I am in trouble? Just seems like they should be up by now. I've read that if your soil has too much clay that they could die over the winter. I have good soil, but it could be slightly on the heavy side. Hmmmm.... They are guaranteed, so I can replace them this spring (good thing since they were not cheap!), but may have to do some soil ammending when I put them back in.... Any advice is appreciated.
