Hi everyone! Happy new year! Why does sweet alyssum I find at garden centers look nice, short/compact (4-6"), and full...and the one's I've seen people home grow (on youtube) and the one's I've grown look leggy and scrawny? I've used the standard "carpet of snow" alyssum..and I can't seem to get them to grow short and full-looking. Does anyone have any tips to getting them to grow like the ones at the garden center?
