Does anyone have a Sago Palm that has two sizes of fronds? I have this one that came with the shorter lengths and last year, after I set it out in the sun for a month in the summer, it grew 3 new fronds that are really long [ 19" ]. This year I did the same sun exposure to get new fronds and I got these two short ones [ 9" ]. I rather expected more long ones. The two sets of growth even developed differently. Anyone else have this experience?
