As the patcher states so boldly, it is plant-a-palooza season! You can read all about it here. Basically it's an "up to" 50% off sale on those awesome crown plants, and they've introduced a new plant, the Ivy League, and brought back the Happy Holidaisy (where's the giving tree! ;))
Awww, just look at these little ivy league babies!
Here's a list of their likes that have been found so far (minus pixie).
I don't know how many people out there know what these things drop as a harvest . . . they're too new! But with the price they're going for, my money is on Hambrosia. ;)
That'd be great wouldn't it?
I currently have my garden as half Evil Magma Pea and half Ivy League. All I had to do was plant my boom shroom a few paces away in the opposite direction of the Ivy League. That'd be a no-no since the Ivy League don't appreciate the subtleties of exploding mushrooms. Pffft! At least magma peas don't care about fickle pickles and despairagus.
I'll let you know if I find anything out and vice versa, k?
