I'm a newbie here, although I've been active in r.g.edible and r.g.roses for some time. But since there isn't a r.g.perennials, at least on my news server, this seemed like the best group for my question.
We have a raised bulb bed, filled with "flower mix" soil from a local soil/gravel/bark vendor. We've had it for several years.
The problem is this. My wife planted it in tulips, all different kinds and colors. With the exception of a parrot tulip or two, they all now produce yellow blooms. Healthy plants, nice blooms, just not what we planted.
Over the last two years, we've gradually replaced the tulips with lilies. Guess what? Same thing! We now have one red lily and the rest are all yellow. Spreading like crazy, so they must be nice and healthy as well.
I asked a local garden "expert" about this back when it was only the tulips, and she said that cheap tulip bulbs would do that. I wonder what she'd say about the lilies :-).
Anyone in this group have a clue what's causing our bulbs to change their flower colors?
Thanks in advance for any and all advice.
