When these nasturtiums bloom, I really do wonder why I bother struggling to grow orchids. They're such gorgeous flowers, so easy and floriferous. This variety 'Alaska Red Shades' has beautiful variegated foliage, too.
This one is 'Phoenix' with fluted petals and leaves.
My rampant vine of Thunbergia 'Spanish Eyes' is not deterred by the chilly weather and lack of sun. Blooming abundantly in yellow, orange and reddish. All on one plant.
Calendula 'Snow Princess' bloomed well into July for me last year, but doesn't mind the cold, either.
