I've completed the Outdoor Enthusiast aspiration twice since Seasons came out so no... You just need to learn when the plants blooms and work with the new system. If you are having some other bug you should report it.
The science lab plants are borked though for me also. I've reported it as a bug. My scientists just grow their plants in an indoor garden at home as a work around for the time being until it's fixed. Have you reported this bug @KirbySkywalker?
Here is the link in case you haven't it helps to go report it so it get's fixed sooner
