I have difficulty with Asian lilies.
Please give me some advise. I have trouble growing Asian or oriental lilies. most of them are short and only a few develop buds and bloom with only one or two blooms. I have always thought that they have been killed by spring frost. But, this one group gets large full sized buds and when they fnally open there are no petals or stamins. See picture. What is wrong with them and what can I do to correct the problem?
