A 4" pot might not fit your size expectations this year but they grow fast and by next year it'll be making a nice full plant, and in a few years you'll have plenty to divide. Personally, I'd go with 3-5 4" pots, but if you want maximum impact the first year you'll want the larger pots.

THANKS SO MUCH!! TAMRA

Just thought I'd throw in a comment about May Night. I planted a one gallon several weeks ago, and it has been knocking my socks off. What a great plant! My East Friesland salvias have also been good.

Hey Tamra!
I just purchased 3 1-gallons of 'May Night' and was wondering about the growth/spread too. I really wanted to replace all of my liriope clumps with 'May Night' (I'd need a heck of alot more), but DH, who knows nothing about flowers, said it looked like a fierce spreader. But now, I'm wondering where I'll even put these 3. There's always the extend-a-bed option ;)

May Night will spread a bit but it won't become invasive or anything. It would look really good replacing the liriope as long as you can keep it deadheaded to promote reblooming. One plant will end up covering an area between 2 and 3 feet and up to 18 inches tall.

Adam-

I am also new at gardening, and my usual question is thus; how DO you deadhead a salvia? Just pull out the spent blossoms from the spike, or cut the spike off below the flowers once all are spent? My May Night is gorgeous, and I'd like to keep her that way.
