to Hope and subjunctive mood

[Little man]

Dear teachers, could you please tell me it is possible to use subjunctive mood after "hope (that)".

I hope that she realise how much I love her.
I hope that she should realise how much I love her. I read that in British English it is more common.

I know that we can use subjunctive mood to express importance, for example after words like "important, vital, to suggest, to recommend'' etc. But can we express desire with subjunctive?

We use the subjunctive more in American English than the Brits do, but not after a verb expressing mere desire. For example, It's essential that you be comfortable with the subjunctive.* I hope you will learn it.

*(It isn't really.)

Thank you all.
One more question about the verb "to hope".
It is true that I can use present simple after "hope" if I refer to future?

I hope you understand it.
I hope you will understand it.

For me the first sentence is quite ambiguous. It may refer to the present or to the future. However, if I add "soon" the ambiguity will disappear.

I hope you understand it soon.

Without "soon", the phrase expresses a desire for the present. Adding "soon" casts it into the future.

We use the subjunctive more in American English than the Brits do,

Any use of the present subjunctive other than a few fossilised phrases is more than most Brits. You could go for weeks or months without hearing it.
