Bulbasaur, Ivysaur, Venusaur, Butterfree, Oddish, Gloom, Vileplume, Venonat, Venomoth, Bellsprout, Weepinbell, Victreebel, Exeggcute, Tangela, Hoppip, Skiploom, Jumpluff, and Tangrowth can all learn sleep powder when they reach a certain level.
Just level it up, I think to level 18 or 20.

Venusaur learns Sleep Powder at level 15, but assuming you are using a legit, evolved Venusaur, you can do one of these two. 1. Train an Ivysaur to learn Sleep Powder at level 15 2. Have the move tutor teach it to your Venusaur (I don't think move tutors exist in Pokemon Red/Blue/Yellow)
