shazza 3: I was like you. Full of expectation buying stuff from catalogues or online. Here on the forum, we have had quite a bit of horror stories.
1) Delivered the wrong stuff: I was supposed to get Blue bayou dahlia and it is a single with pipes in the centre. After months of TLC, they turned out to be one a double with pipes in the centre and another a dinner plate dahlia peachy in colour with white tips. Was supposed to have all double osteospermum, but half turned out to be singles which weren't what I wanted. Of course, you only find that out half a year later!
2) Some arrived totally dead. Some arrived with reams of roots, but no stems..
It's a good idea to label your stuff and keep details of WHAT YOU HAVE ORDERED and where you have ordered them from and compared what you have got half a year later. You can get a refund, but imagine the disappointment. You expect a Ferrari but get a Robin Reliant!
