If you’re looking for something to do tomorrow (Sunday, March 26th), I highly recommend the Zilker Garden Festival. Plant and arts and crafts vendors from all over Austin come to show and sell their stuff. There are landscape plants, flowers, herbs, succulents… all kinds of plants for really great prices.
Personally, Brian and I bought a shirt (their logo is pretty sweet), some air plants, a type of orchid, lavender and lemon balm plants, and a bar of delicious smelling lavender soap (for me :))
Inside the exhibition hall, there are plants on display in with various awards. There are several artistic categories you could enter plants and arrangements into. Really awesome!
There are also food trucks (Amy’s Ice Cream!!), a beer garden, live music, and plenty of beautiful places to sit and relax. Then, of course, there’s the actual botanical garden itself (I’ve been a few times. If you’re interested in seeing more photos of the gardens, I have some HERE and even more HERE.)
If the weather is as nice as it was today, I would definitely recommend driving down to the Zilker Garden Festival.
