Add a title to the blog page ONLY

Hi

I would like to add a title to the blog page only, NOT the single post pages. Also only need it at the top, as page title.

I have used GP hooks below but the result was:
- "This is my blog" added to the blog archive page, above EACH blog post summary - I only need it at the top of the page.
- "This is my blog" was added to the top of each single post page.

* GP Hook used *
<?php if ( is_home() ) : ?>

<?php endif; ?>

Thank you in advance for your help.
