Some of the little rockery in the front garden in early April

 This lovely anemone grows by the David in the area I am calling the Magnolia Tree room.  It might be a deCaen or a St. Bridgit.  There are also some nice Tulips in this area.

 The purple aubretia that grows on the little gold rock wall across the stone path from the West Coast planter.  There are some scilla growing in the same area.

The bergenias are growing nicely this year.  I gave removed a couple of flat rocks and gave them some good top soil.  Some information from the internet.  Beth Chatto garden has a nice photo of a perennial garden:
 Bergenia, also known as pigsqueak for the sound it makes when two leaves are rubbed together, 
fills that shady or dappled spot in your garden where so many flowers shy away. Bergenia plant 
care takes very little time, as these are low-maintenance plants.
Plant them 12 to 18 inches (30-46 cm.) apart early in the spring to fill the area without 
crowding them out. Choose a spot with well-drained, moist soil, and add compost to the bed 
as needed. Plants are evergreen with interesting foliage colors in winter.

Beth Chattos garden has an interesting photo of the garden using various perennials.
Elephant’s ears, bergenia are one of the most indispensable and widely used evergreen 
plants here in Beth Chatto’s garden but there are few plants that seem to provoke such 
polarising views among our visitors.

 This iberis grows at the front of the little rockery, next to the stone path.  This from before the clean up of this area.  The iberis did much better after clean up and a bit of new top soil added.

 The mountain avens before clean up.  I have better photos of this lovely little sub-shrub from other years, but this is the one from early April this year.  More information from the internet:
Mountain Avens (Dryas integrifolia/octopetala)
These plants are ground-hugging, sun-loving, semi-shrubs.
Arctic mountain avens (Dryas integrifolia) leaves are 1-2 cm long, 
narrow with smooth edges and a somewhat shiny upper surface.
Alpine mountain avens (Dryas octopetala) leaves are longer (up to 3.5 cm) 
and wider, with scalloped or wavy edges.
Leaves & Twigs: The small, leathery, evergreen leaves are wrinkled on the 
upper surface and hairy underneath.
Flowers & Fruits:
White, saucer-shaped flowers are 2-3 cm wide, growing on stalks 2-15 cm tall.
Seed plumes are twisted in tight red/gold bundles that open into fluffy round 
seed heads as they mature.
Habitat: These species prefer rocky barren areas, alpine meadows and ridges. 
Arctic mountain avens can also tolerate moist conditions, where it takes on a 
creeping form.

The sedum that is forming a very nice ground cover for the 'inner garden' that is the smoke tree area. This is before the clean up.  You can see the leaves and alliums in the sedum.  Since the clean up a few days ago the sedum has bloomed with its yellow tall sprays of flowers that enhance the red geum that  grows out of the carpeting sedum.  I am not sure which kind of sedum it is; but spathule or spuruim are my best guesses.
