Atomic', G. primulinus 'Mirella', a miniature all red species-type of Glad, in a vintage vase that was my mothers, on our front porch.
Abutilon ' Firefly', is a nicer selection of the Flowering Maple. This cultivar remains small, almost dwarf. Our stay under 24 inches tall, yet are covered with red bell-shaped flowers all summer long ( and in the greenhouse, for much of winter, too!).
Red Geraniums ( Pelargoniums) are fine, but the variegated leaf forms are by far the best. They remind me of my childhood, so I always try to keep a few in the greenhouse and on sunny windowsills in the house. Nostalgic and attractive even when they are not in bloom.
Begonia boliviensis, a rather new hanging species begonia for baskets and tall containers for summer fire.
Variegated 'Crown of Thorns' 'White Lightning' ( Euphorbia millii) looks great in the winter, when it only has foliage, but in the summer, the summer thunderstorms coax out the bright red flowers making it worth while as a deck plant.
Yeah, these are those Chinese geese that you saw in many June posts. Almost full grown.
Red Single Dahlia's enjoy their season - August. Mixed strains of 'The Bishop' and seedlings, adds needed color to the perennial border.
