By contrast, catnip has a rather weedy appearance and is rarely grown as an ornamental. Nonetheless, it is king of the catmint plants because of its effect on that diminutive “king of the jungle.” Here are all the varieties of catmint plants you can incorporate into your garden. A common landscaping mistake for first-timers with 6 Hills Giant is the failure to give it enough room. The herb will end up dwarfing any smaller specimens installed around it. This catmint plant should be sent out to play with the big boys lest it bullies the little ones. Likewise, if you are going to use it as an edging plant for a walkway, do not plant it too near the edge of your path or it will spill over and impede traffic. Similarly, you can let it fill in that gaping hole you have in the front row of a flower bed, but be sure to set it back three feet or so. Otherwise, it will hurdle over landscape timber edging (or whatever type you use) and become a nuisance when you have to mow or weed whack. However, properly situated at the front of a perennial bed, it can serve as the foreground for taller plants such as hollyhocks and still hold its own. While 6 Hills Giant can play with the big boys, Little Titch is easily overwhelmed. It is just as tough (drought-tolerant) and just as long-blooming as its bigger cousin, but choose petite friends for it if you really want to show it off. A prominent nook in a rock garden might be just the spot for this dwarf catmint plant. So might any landscape plagued by deer, as Little Titch (indeed, most types of catmint) is a deer-resistant perennial. Humans have put catnip to various medicinal uses for themselves, too. That’s right, catnip is not just for cats. Ever heard of “catnip tea”? While this plant will make your feline friends leap, roll and frolic, it has just the opposite effect on humans. It makes a good choice if you want a relaxing blend in a tea, and can be safely given to gentle over-excited children. You can also draw wildlife to your landscape by growing catnip (or many of the other types of catmint plants), including butterflies. hummingbirds and several species of pollinating bees. .
