I bought some of those last year, Lynn. Exact same ones as you did plus some solid red ones. The bulbs are huge this year. One of them rebloomed for me during the summer! They are planted outside in the ground (as we have mild Winters in Florida).
I bought several of these amaryllis on clearance at Wally World for $1.50 each. I may buy some more this year when they are discounted or clearanced again. A very elegant plant and bloom! I felt like I got a steal of a deal for the clearance price!
