I never met a Lavender I didn't like. My bees love it and my skipper butterflies can't leave it alone. Lavender is extremely hard (nearly impossible) to grow from seed. Of course the seed packets won't tell you that. The good news is it is one of the easiest to propagate. If you have rooting hormone (just a little packet from the garden store) you'll have a near 100% success rate. Cut off a 3-4 inch cutting from your mother plant. Strip off the bottom leaves leaving just a few leaves at the top. Dip it in the rooting hormone, shake off the excess (too much hormone and it will inhibit growth) and then plant in a potting soil leaving your top leaves sticking out. I like to water from the bottom as it gets the roots to stretch down. I don't let them sit wet though. I don't look for roots until I see new growth on the plant. Usually lavender likes the worst soil in your garden as long as it gets sun, and good drainage. Wet feet will kill them. They usually will need some water the first year, a little the second to help them get established. The 3rd year unless you're in an extreme hot area, you likely won't have to water again. I have never fertilized my lavenders, though some people will add bone meal to the plant. Where I am, I'm unable to overwinter the delicate, spanish lavenders. Those are the ones with the fluffy flower heads, and foliage that has a pretty, ferny look to them. There are about a zillion others I can grow in my area, and I think your Lowes or Home Depot should have them. One of my favorite sites for lavenders is Goodwin Creek Gardens out of Williams Oregon. They have an incredible variety, and have even developed thier own. Their web site as a plethora of knowledge regarding lavenders and other herbs. My favorite treat is to buy one of their plant collections. The plants are smaller than what you'd pay for at Lowes, but the variety is astounding, and you can get some very special plants here.
And another thing, (sorry I'm so long winded) I LOVE Bee Balm aka Monarda aka Bergomot. The fragrance is lavender and lemony at the same time. It's vigorous, and next year you'll have twice as many plants. Hummingbirds love it too. I good one to plant near a path where people will bump into it.
