Impatiens

This busy Lizzy is not the free-wheeling wild times tropical annual of your Grandma's time, this is the conservative backlash foliage over flowers, year round workhorse Impatiens. Hardy down to the warmer parts of Zone 6 this is a great plant to add some tropical flavor to your less-than-tropical perennial woodland garden. Plus happily spreading and easily dug to share with friends! Wheels of lime or silver-streaked dark green leaves centered in red with yellow balsamineous flowers in Summer. These are cutting grown from a particularly narrow form at the old Heronswood nursery. 

An exciting tender perennial Impatiens from Vietnam we brought in via the UK. Deep green leaves with magenta undersides on a stout 3'-4' upright plant are quite enough but add the late orange-yellow flowers with red lips and be ready for involuntary expletives and religious exhortations. We saw this in the wild and were blown away. We overwinter ours in a cool greenhouse. Far Reaches Botanical Conservancy Collection

An awesome - and I don't use this word lightly - hardy Impatiens from Eastern Africa. John Grimshaw in the UK speaks highly of this species. To 6' tall in morning sun or light shade with awesome (there i go again) 3" wide flat-faced white flowers with a red throat. Gorgeous. Perennial big tuberous roots. Not a seeding bully.
