I got a second quest from Esther just now for Black Hibiscus. I bought the item and refreshed the page on which Esther asked me for the item to be able to hand it in, but the button to hand it in did not show up. I checked my inventory to make sure I had the item she asked for and tried again, but no result. I didn't find any thread with this problem. Should I file a ticket?

Is she asking for a fresh hibiscus? Because you have to buy the seed and plant it. That's what I had to do earlier.

esther asks a flower > you plant the flower seed & set the alarm > you get the event saying the plant has bloomed & that you can give it to esther > finish quest esther gives you 25 coins.

Oh, I didn't know that! It just says black hibiscus (no "fresh" added), but this might be the problem! I will try that, thank you very much!

Growing unfortunately takes a very long time, so I don't know yet :/

Well carp. I gotta plant the magical grapevine? I bought it. At least now I know. Thanks for posting this topic.

Oh, I planted it in the (normal) gardens, I didn't know Esther had a garden, too. I kinda feel like an idiot now, sorry :D Thank you for all the help!
