I have to admit my personal favourites always include flowers, but I'm one of those women who loves plants / flowers in the house all year round. For our centrepieces we shopped around for inspiration for quite a while until we knew what we wanted and where we could get that on a budget. Our flowers are being grown by family and we are placing them in oasis in £2 pink jugs from Wilkos (similar here), with the top table jug being a white version from IKEA (similar here). On our cake and table for cards we are using these very popular IKEA plant pots, which I already own. You can see what they look like with a plant in here.
