April in the Northern Hemisphere

Omphalodes cappadocica seems to love it here. Seedlings pop up all over the garden in shaded positions. I have seen the fairly big seeds being dragged along by ants.

Sown ten years ago from wild-collected seed via the AGS, the extremely slow-growing Rhodothamnus chamaecistus is finally showing its full potential. The flower buds are formed in the autumn and in previous years they would often fail to open in the spring. This winter I covered the plants with a pane of plastic and all the buds survived to open this month. To my delight, one of the seedlings that had always failed to flower turned out to have almost white flowers with faint pinkish stripes in the centre. The plant on the right has the more usual pink colour. Although this grows on limestone in the wild, it must be cultivated like a dwarf Rhododendron, in a well-drained acidic mix that should not dry out.

Shortia uniflora is a jewel among the woodlanders but not easy to keep going in the open garden (at least in my garden). It does better in a large pot with gritty ericaceous compost that is kept out of the sun but not in deep shade. The flowers are more pinkish than they appear to be in this photo.

Some more Ericaceae flowering now.

Cassiope lycopodioides 'Jim Lever'
727094-1
Kalmia microphylla
727096-2
Rhododendron calostrotum 'Gigha'
727098-3
Rhododendron primuliflorum 'Doker La'. This is often compared to a Daphne, which it does resemble in the small flower size, but unfortunately it lacks the lovely scent of that genus.

Rhododendron pumilum

Some 'other' plants.

Coluria omeiensis var. nanzhengensis. For some reason this Chinese species had not flowered here for the last few years, so I was pleased to see a bud recently that has now opened. It could be described as a Geum species that tries to imitate a primrose. The flower is about an inch across.

Cypripedium formosanum is starting to outgrow its allotted space. I believe this is called a luxury problem.

Lonicera sempervirens. A vigorous climber that is here barely evergreen, in spite of its name.

Sometimes the constant battle with slugs and other vermin is rewarded, Maggi.

Let me add Androsace geraniifolia, which must be one of the easiest and fastest-growing species in this genus. This was grown from the 23/24 seed distribution of the SRGC, so it is already flowering only one year later with up to five inflorescences per plant. It is an evergreen woodland species that survives without any protection in the open garden. I wish all androsaces were this accommodating.
