A rose in bloom in April in New England? Outdoors, only if the season is unusually warm and the shrub is Rosa hugonis. Or, in this case, if the rose is growing in a greenhouse. This chaste beauty is 'La Mortola'. It isn't solidly hardy here, so I grow it in a large container that's moved into shelter November through April.
'La Mortola' is the best form of himalayan musk rose. It's once-flowering, and when that happens in April it's still greenhoused, so no one but me will see its display first-hand. I need to convince the shrub to flower a month or two later, by which time I'll have moved it back out into the garden. One of my Spring-flowering tropical trees, jacaranda, is a plant to look to for guidance.
