Any lilac expert around?
I planted a one gal lilac last year (Lavender lady). It has bloomed this year. This year I put in a 'Ludwig Spaeth', a bigger and more robust plant and a late bloomer. It has leafed out nicely, but has no bloom buds. The nursry person said it could still bloom this year. I doubt this because it is my understanding that lilacs bloom only on year-old wood. True?
Also, all the Ludwig Spaeths at the nursery (this morning) were bloomless and budless, and all the other varieties had blooms and/or flower buds. What's the deal with Ludwig?
