That's how my Lotus bloomed last year. My big one had 8 on it, a few opened then the end of the week the rest opened. No other blooms the rest of the season. This was an established Lotus.
Babydoll Lotus, had 2 blooms and that was all for the whole season it was a new Lotus.
Started 4 new ones this year early in the greenhouse, they are just now getting ariels.
I wonder if its the variety or the size of the plant. Mature plants get more buds??? They only bloom certain time of the season per variety. Com'on Lotus people, Tink has a great question.
