Try to grab some Ice Flower Seeds in Svargrond and sell them for a good price. Most people would buy it to make their flowers permanent and get the achievement “Preservationist” and then be also able to sell it. I would also advice you to collect the seeds from the mobs and buy some pots in the NPC in Port Hope, grown the flowers, make it permanent and sell it after a while, when you can’t find those flower so easily.
I hope it helped :)
