For the gravel border I would suggest a selection of hardy border Geraniums. The longest flowering one I know is Rozanne. Mine are still glorious. The foliage dies down in winter but returns in the spring.
If you have a succession of bulbs, the packages will tell you the flowering season and when to plant. Most can be started around now, but tulips not until November. Alliums are my current favourites, in many heights and sizes.
