You've got a few things going in your favor of WSing these succesfully. The word "Wild" is in the common name. Looking this up shows that it's a native of Afghanstan--it's freezing cold there in the Winter. It's hardy to zone 5.

I just signed up for Beestar and I'm so happy to see my son having some fun while learning online with the math exercises. The math exercises are free and they're the perfect supplement to his online learning through school right now while everyone is home. If we like it, there's a small fee to sign up for other subjects, so we may try those if this continues to go well. Take care everyone!

Notice that the FAQ on the site does not include information on the volume of water needed to fill the tub! Well, I did the math. Their smallest recommended size is about 65" long, 34" wide and filled about 16" deep for a bath. Note that this is not an impressive shower size. (The one in the ad is probably 60 inches wide.) That is 153 gallons of water. This 2 person air massage tub at 23" deep uses only 2 gallons more. There is a lot of cubic area lost to corners in a square tub. The one below uses 2 gallons less than the smallest recommended size and depth of your "Roman Shower" and it has a depth of 19.5" inches. Note that the woman in the Roman Shower video seems to have only 8" - 10" of water when she leaves the tub. Disabled, elderly, or otherwise less mobile people would have a heck of a time getting out of the "tub" with the Roman Shower, too. There is no heater for it, either. By the time it was deep enough for a bath, the water would have cooled a lot, warming up all the tile and substrate in the Roman Shower with its excess surface area with square corners. It may be a step above the home made sunken roman baths of the 1960s and 1970s, but it is nothing like a comfortable modern bathtub.

Dave, I know that some multi-generation hybrids have lost the three leaf "tri". I imagine that this probably still has the three leaflet presentation, but was curious to see the leaf structure of what is a first gen hybrid (I'm assuming just a normal trifolate leaf).
