-My garden?? Let's see...

Daffodils are lovely. I need to get more daffodils next year - all kinds, especially I like the white ones...

Some little guys are also blooming already - a dwarf hyacinth, and some survived pansies (are they biennials?)
Tulips, and irises are also coming, and there are some other spring flowers - I've no idea what are they, hyacinths, probably?- we'll see soon:)
Unfortunately, I have no crocuses - I am going to get some! May be some primroses, too...
I wish I knew more about plants and gardening! I guess it's the beginning of the gardening season, but I don't know what to do, when to plant the stuff and how to make it grow well. I don't find gardening fascinating so most likely won't spend a lot of time taking care of the plants. Still, I want my front- and back- yards to look nice, and I love flowers. So I am trying to figure out what to do... Guess, I need
a japanese gardener to plant some hardy perennials, that will be around for a while, and won't be too hard to take care of. Can somebody recommend some easy to grow perennial flowers? Something rather tall, with nice-looking foliage... And some small crawling flowers too? Please?
Yesterday I spent some 30 minutes starring at the shelf with the boxes of the flower bulbs/tubers/whatever and bought a Gallery Dahlia, a Japanese Windflower, and some Blazing Stars. I also got seeds - Cosmos, Columbine, Starflowers, Sweet Pea, Zinnias... All those are summer flowers. The question is when it's it's okay to plant them? The package says "after the danger of frost" but how the hell should I know, especially here in the mountains in Northern Colorado, where the difference between day and night temperature is more than 30'F (10-15'C?)? Why they just don't say something like "мid-April"?
Also, I want to plant some herbs for my kitchen. Ones again, I have no idea when it should be done. Sasha has big plans - he wants to grow tomatoes, and pumpkins, and stuff. Guess it waits until May-June, right?
See, I know absolutely nothing about gardening! :(
So, for now I am a)-enjoying the daffodils, b)-trying to guess what all those coming plants are c)- giving a haircut to the bushes (hard work!) d) - exploring.
Exploring is the most interesting part.
I have a small landscape bridge there. It's old and is about to fall apart, and I have to do something about it, because it's very cute. Japanesque. Giverny-sque! :) For now I cut down the branches around it so they won't block the nice view.
I found a bunch of nice patio pots (good!), and two huge, massive cubic planters. Now I am trying to figure out what to do with them.
There is also an old covered bench/gazebo/whatever, which is going to fall down pretty soon, if I won't do something about it. I am not sure what to do with it, and not sure if I want to keep it. What a pain in the neck.
And there's a thing that I definitely don't want to keep, and it's a birdhouse stand, comes with the various bird feeders, and a half-a-ton of birdseeds and nuts from the garage. I have to get rid of it ASAP: from my point of view to have two cats, and a birdhouses in one yard is irresponsible and cruel. I need to find someone who'd want it. It's a pretty solid structure, and would make any bird-lover happy... so I need to found one.
The bird bath stays, I guess - it looks ok, and i've never seen any birds around it:)
Snooping around I found some funny-shaped stones in the bushes under the weeping mulberry. I dug them up, and brought back to the garden (heavy!). My cats also were curious about this finding...
( +2 pics )It turned to be fragments of an old stone lantern or something like this.
So I used it to build a small garden pagoda:)
( +1 )I am going to plant different kind of flowers all around it.
I think that it goes well with the spirit of my garden:

Wow, it was one long post! :D But yeah, I'll probably will keep pestering you with my gardening problems and ask more stupid questions. Like: what the hell is this compost pile and what to do with it? Can I go without it??- The whole thing sounds kinda disgusting to me...
