Oh Gosh yes! I always wait for the Gardening tour and then fill out my flower bed but leave an open spot. Then i have 3 minutes to get whatever i want I always thought the purple lilys were rare so i freaked out that i could take them x)
For me the best tour to raid flowers from the island is the butterfly discovery tour. They're easy medals, and there are tons of different flowers. Sometimes I can even go for specific types and still fill my pockets with enough time to spare to catch 8 to 12 butterflies.
Dreamies have: Pecan, Yuka Annalise, Diana, pekoe, peanut
dream my town, i leave treats and fun stuff
Oh man. For a second I thought you meant like... real peoples' flowers, haha. But yeah. It's a really easy way to get lots of flowers. The prices from the hippy sloth guy are fine, it's just annoying that he only sells 2 flowers a day (for me).
