I have a suggestion... since you are on hubpages and I assumed you are familiar with making money online...
Why not create a detailed e-book about gardening. From basic information to the techniques you are using to successfully grow your garden.
Make your own website and sell your book there and start promoting it. And, I think you can also sell it in Amazon, I'm not sure the exact procedure about publishing in amazon.
That way... you have your income selling flowers and the same time you're selling your ebook.
