Yes you indeed can. Just because a item is on clearance doesn't mean coupons are invalid. In fact most coupon experts wait for the item to hit clearance because that way they can get the product for practically free. I do it all the time.
In the past in my experience I have always been able to use my coupon codes for Home depot on any item. I have never purchased only clearance items, but I don't see any print that says it is not valid on clearance. The best thing to do is just try the code and see if it works.

You can find current home depot coupon codes to use for online purchases at websites such as www.retailmenot.com, www.mahalo.com and www.couponcabin.com
Plants are available at Home Depot, and if you have an applicable coupon then yes you are allowed to use them. As long as the coupon itself isn't expired, you should be in the clear to use it if you have it with you at checkout.
If there is no expiration date, chances are that the coupon is still good. In order to find out for sure, you can call your local Home Depot and ask them.
I do not believe that you can purchase a Home Depot coupon code online. Occasionally on their site they will have a special offer that will direct you to enter a special code upon checkout for a specific discount, but I am not able to find any information on actually being able to purchase a coupon code. Hope this helps!
It really depends on what the coupon that was sent to you says. Most coupon codes are good online only, but there are some companies that allow you to print the coupon code and redeem in store as well.
In my opinion the best way to use your coupons is to stack them. Get a coupon from the Home Depot store which is considered a store coupon. Then get one from the company that produces the product which is considered a manufacturer's coupon. These two stack for double savings. If you have them both then try to get the product on sale or clearance and you will save a fortune.
