Impatiens arguta
Hardy Impatiens, Balsam
Zone: (6)7-10  
A
VERY cold hardy, tough, long blooming Impatiens. May die back
but resprouts when temps get above freezing. Even
takes dry shade in stride. Lavender blue 2" trumpet-like
flowers are charmingly asymmetrical adding a bit of whimsy to the
garden. Blooms spring through Fall. Lovely in handing
baskets (but remember, out of the ground, plants are 2 zones less
hardy). Serrated green leaves and red stems. Gets VERY
wide in one season but is still a Clump Former, not a spreader and
tall plant and easily grow up through it. Grows 6,000'-9,000'
in the mountains from Nepal, Tibet, and into western China.
The blooms do tend to hide beneath the leave but there are so many,
you can always find some to look at.

Impatiens
mengtszeana TENDER
Perennial Impatiens, Mengtsze Balsam Zone: (8)9-10
  
Beautiful, luscious
soft golden yellow, 2" trumpet like blooms are blushed with peach
and look dazzling next to the red stems and shinny serrated green
leaves. This one is a Fall Bloomer, October through December
in the tropics. It's also stoloniferous and forms a
groundcover to 15" tall and 36" wide. Excellent trailing over
a wall. Sadly, needs to be grown indoors except in Zones 9-10,
possibly 8. But takes to pot culture with ease. HOWEVER,
it can be grown in colder zones as an annual as they do at
Scott Arboretum, where it blooms from Sept. until Frost.
(Nice photos at that link.)

Impatiens omeiana
Hardy Impatiens Zone:

Late
to come up in Spring (May in Zone 6). Beautiful, narrow, elliptic
dark green foliage with a white stripe down the middle of the
leaf. In late mid Fall, it's top with yellow flowers that are
like elongated snapdragons. Foliage looks great all
season. This stoloniferous politely forms a nice patch.
Very rare.

Impatiens stenantha
Hardy Impatiens, Narrow Flowered Balsam
Zone: 7-10
 
From high mountains in
Yunnan, China, so it's quite hardy. Yellow orchid-like blooms
with long spurs and red freckles in the throats from Spring through
Frost. Looks like a yellow long tailed butterfly!
The trailing stems have dark green scalloped leaves with a tinge of
red and with red mid-ribs. Quite the display.
Good trailing over a wall, as a groundcover or in hanging baskets
(and brought in in zones colder than 9)

One of our best rock garden, front of the border plants. It blooms for weeks and weeks, from July thru Sept. frost when very little else is blooming in the rock garden. Easy in sun or part shade. Needs well-drained soil. Self-seeds some, if happy. From Japan. Indifferent to Ph.

Iphion uniflorum
Spring Starflower
Zone: 5-9  
A native of Uruguay.
Iphion are great for planting in a rock garden, borders or for
under planting w/ Peonies or Hostas. They naturalize well & once established, produce masses of quarter size flowers for up to 4 weeks. After a major bloom in late spring, they continue to surprise you on & off all summer. Divide if they start to be crowded.
This is so-o-o-o-o pretty!

Iris cristata
Iris, Dwarf Crested Zone: 3-9  
Iris cristata is happiest in moist woodland. Eventually makes a gorgeous groundcover but doesn't romp all over its neighbors. A tough,
accommodating, little plant that needs division every few years to maintain the mass of flowers for which it is known. Fragrant & beautiful. So
drought tolerant in shade that it will live happily under a Maple tree!

Iris pseudacorus
Yellow Flag
Zone: 4-9  
Yellow iris is
excellent for borders & massing. It's 'Unlike Anything Else' yellow flowers are one of the first arrivals of spring. No hype -- truly SPECTACULAR. It is a vigorous grower, especially in a wet spot or even a pond. A strong grower in average soil. The easiest of all Iris to grow -- nothing bothers it.
A lemon yellow color that I've never noticed in any other plant.
Soil:

36-60" W: Indef. B/M: Lemon

Noxious Weed:
This plant can be weedy or invasive in certain areas.
Ours have limited themselves to a wet ditch where they were planted
and become a 4' wide clump but in some areas they have been banned
due to spreading too much. It certainly should not be planted
in or near a wetland area that you can't control.

Iris pumila 'Yellow'
Iris, Dwarf Yellow Zone: 6-9  
We not sure about it's Latin name, but we keep it because it is extraordinarily beautiful. A dwarf iris with beautiful yellow flowers. Behaves well and doesn't have to be divided as often as it's bigger relatives. Semi-evergreen & very quick to multiply. Unlike the big bearded irises, it doesn't have to be divided. Just keeps on ticking.

What you're saying about us...

Looking at the way you ship a lot of TLC goes go into your plants. I have ordered from
other places before. Most places have the plants in a plastic bag.
I never received them in a pot before. Thanks Again.

Iris tectorum
Roof Iris Zone: 5-9  
An iris especially suited to the rock garden but larger in all its parts than most suited for that purpose. Fans of broadly shaped, ribbed leaves, stout rhizomes. White crest on bright lilac flowers.
Likes moist well-drained soil but tolerates dry well. Prefers a sheltered sunny site. This
is really an exquisite, easy iris.

Iris wattii? (Iris confusa? Iris
japonica?) Bamboo Iris Zone: 8, maybe colder.
We
purchased this 5-6 years ago from China as I. wattii var. but there's a
chance it could be Iris confusa or possibly even a natural hybrid between I.
wattii and I. japonica. (Hardy to Zone 7, Iris japonica would have given
extra hardiness.) I. wattii and I. confusa are not
supposed to be very hardy and these live in our greenhouse which is
allowed to freeze in early winter. They look
oh-so-similar. See photos on the above link.

Iris
x 'Black Gamecock' Louisiana Iris
Zone: 6-10   
While
you might expect to find this in a water pond, and rightfully so, it also
grows beautifully in the well-watered or damp garden. The Louisiana
Irises can lengthen the Iris Season. All the Louisiana Irises are beautiful, but this one is in a class by itself. Blue-black with yellow signals. Safe in earth bottom
ponds by the way.
Soil: Average to wet, even in
ponds H:18-24" W: 12"
B/M:
Deepest purple/4-5
