- AzulVerified BuyerRated 5 out of 5 stars6/2/26WOW! Amazing growth!
I am simply amazed at the growth of these plants! I started them under grow lights and transferred out into a garden bed as tiny plugs...now they are nearly 4 feet tall! I will definitely be purchasing these again as they are lovely low maintenance plants that add texture and greenery to the garden.

These were started indoors and germinated nicely. They are almost big enough to put in the garden.
