Hellebores are very good for a winter plant. Tough palmate leaves and flowers that can be out from february , depending on where you live. Can be planted in border or do ok in a pot. Winter flowering honeysuckle worth trying to have a perfume to cheer you. For smaller bulbs to go in pots you could have Iris Recticulata- blues and purples in colour, Iris Danfordie yellow. (not sure on spelling but you will see them ok) snowdrops , crocus. I find it a better show to do a pot of each different one , rather than mixing the colours as they can differ in flowering time, then you can move the pots around so that they give you a view of flowers that are looking good and then bring a different one to the fore. These can be followed by daffs like february gold and thalia and later than that small tulips like red riding hood etc. You are likely to do well with some if not all these and will be cheered when you look out to see something else coming up. Good luck, and find your local gardening club that you could join , where you will find lots of help and chance to buy or swap plants and gardening friends. In the meantime just take a walk in your local area and see what plants are doing well. It is worth doing a soil test in various parts of your garden, - not hard to do - and this will tell you the kind of soil acid or alkaline which will help you to choose appropriate plants that will like your soil.
