I've got four plants with scapes.
ROB COBB has a scape that's about 12" tall already. SAVANNAH KNOCKOUT has a short proliferation with one bud at the top. Orangman has a scape and so does Lemon lily. Those two are always early, but seem to be even earlier this year. I checked my records, and Orangeman usually gets it's first bloom mid to late May and Lemon lily's first blooms are usually in early June. Peak bloom here is mid July, but this year everything started growing early, so I'm thinking peak bloom may be earlier as well?
