Annual Flowers For Partial Shade

Snapdragon is a tender perennial, frost tolerant but treat it as an annual in a colder zone. The long cluster flower spike is excellent for cut flower and good for edging. Cut the spent flowers to encourage more blooms.
Petunia
This flower is the most famous option for a container garden. Although it is easy to grow from seed, it requires indoor seeding about three months before the last frost.

While some of these annual flowers seeds can be direct sow outdoor, but keep in mind if you live in a four season and colder zone, then you should direct seeding after the danger of the last frost.
Otherwise, most of these flowers will die out because these are tender plants. If you plant these flowers from the seed package, always read the plant instructions listed on the label.
Also, check with your region where you live to make sure if these plants are not on the list of invasive plants.
How To Harden Off Indoor Started Annual Flowers
You need to harden off indoor started annual flowers or any plants before they are ready for their spot outside to prevent shock such as wilted, dried out or worse died out, not fun I know.
This process is as simple as gradually expose these plants into the outside environment for a few hours and bring it back inside about two weeks before the last frost date in your area.
You have to increase more hours every day for about two weeks started in the protected shade area like a patio. Then gradually expose it into the sunlight, wind, or rain then bring it back indoor until it ready to be left alone outside for the whole day and night.
If there is frost in the forecast, then withhold the hardening off process. These plants are usually ready for their final spot outside after the hardening off process finish.
What Is The Soil Condition For Growing Annual Flowers
As many other plants, such as flowers, vegetables, shrub or trees except bog tolerate plants, needs well-drained soil with lots of organic matter. Some annuals grow well in a sandy area like those for the rock garden, but it still needs to be well drained.
If you have clay compacted soil, add more organic matter like compost, peat moss, worm casting, or well-composted manure when you work on turning that soil so you will get a suitable growing medium.
I have a clay soil all over the garden, so I would mix in these organic matters with perlite and keep adding more compost or manure every spring for soil amendment.
If you have a small garden, or just building a raised garden box, you can use the premix garden soil. If you use the topsoil package, you have to mix it with compost or manure again before planting.
Some annual flowers or any plants also grow on certain ph balance on the soil. You can test the soil with PH starter kit if you are unsure about it.
How To Water Annual Flowers
Just like many plants, you don't need to water them until it gets waterlogged. If the plants are outside in the garden already, it always best to water them in the morning, so it has a chance to dry out or evaporate before the night comes to prevent plant disease like fungus or blight.
If it grows on the container, make sure the soil doesn't dry out. If it rain comes, then you are lucky you don't need to water them.
But all annual flowers I mentioned here are not difficult to grow and no picky about watering system either.
