CORYLOPSIS

This genus is often considered to be acid loving and indeed will thrive on acid soils. However, with the possible exception of C. pauciflora, they will survive almost indefinitely on even shallow chalk soils. As with so many plants, it is not the pH of the soil that is important, so much as the structure - it is much more important that it is not too heavy and drains well enough in winter whilst holding moisture adequately in summer. 

Racemes of attractive yellow flowers hang from bare branches in early spring and I never fail to be pleasantly surprised by their lovely perfume too.


CORYLOPSIS glabrescens var. gotoana 'Chollipo'
Originating from the Chollipo Arboteum in South Korea, this is a splendid selection. The large leaves are slightly rounded in shape, showing subtle bronze tints in spring and lovely golden autumn colours. Attractive fragrant yellow flowers hang from bare branches in early spring.


CORYLOPSIS glabrescens var. gotoana    
This has the largest leaves of the species that we grow, but they are an amazing shade of green that is almost blue. The delightful primrose yellow flowers hang in bunches from bare twigs in early Spring. When thriving, this can be a vigorous plant, developing into an open vase-shape.


CORYLOPSIS glabrescens 'Lemon Drop'
Corylopsis can be a very bewildering genus from the nomenclature perspective. This is a really gorgeous cultivar, but it doesn't bear much resemblance to the other clones of C. glabrescens that we grow. This one is completely different in its habit, being dense and low growing, with much smaller leaves. It's also one of teh most floriferous, with noticeably brighter, acid yellow flower.
See it in the Quarry Garden and Woodland Walk.


CORYLOPSIS glandulifera 
This is a rare Chinese species, and the plant that we obtained under this name has become one of my favourites in the genus. It is rather upright in habit, with longer, comparatively narrow leaves (particularly when it is young and growing strongly) which add to its elegance. The primrose yellow flowers in March are typical of the species and (to my nose) particularly sweetly scented.
See it in the Quarry Garden and Woodland Walk.


CORYLOPSIS pauciflora  
The smallest growing of the genus (to 2m) with small leaves which are bronzy when young. Large primrose yellow flowers held singly, often just before the other species. It is also sweetly scented. A truly beautiful plant but it prefers good well drained soil and a sheltered site.
See it in the Quarry Garden and Woodland Walk.

CORYLOPSIS sinensis 'Spring Purple'    
A gorgeous form with deeper plum purple young growth maturing to deep green flushed with purple. Soft yellow flowers in dense racemes in April. Beautiful but not the most resilient, so the soil structure is all important with this one. The rapidly extending soft young growth can be vulnerable to late frost.


CORYLOPSIS spicata 'Red Eye'
This species is robust in constitution, though usually remaining smaller in size. It has distinctively rounded, almost heart shaped leaves. The racemes of yellow flowers are equally memorable with prominent red stamens. Good autumn colour.

CORYLOPSIS veitchiana
This well-behaved species seems to be particularly tolerant of heavier soil. It develops an upright habit, with long leaves which are often purplish when young. Large racemes of primrose-yellow flowers are sweetly scented.

CUNNINGHAMIA lanceolata 'Glauca'
This small genus of Chinese conifer most closely resembles the infamous monkey puzzle tree (and in more recent times, the Wollemii pine). It may be necessary to stake the young tree initially until it develops its own dominant leader. It will then grow in layers to create a much more dramatic and architectural shape than many conifers. However, it will get pretty big given enough years. This particular selection is totally hardy despite its almost tropical appearance, and has the most wonderful glaucous leaves, the bloom making the tree appear a breathtaking pale blue. Thanks to Keith Wiley for introducing me to this one and generously giving me a few cuttings to get me started.

CYCLAMEN graecum
I adore Cyclamen in all their forms and this species is particularly special. It emerges and flowers in the autumn, and is distinguished by some of the most handsomely marked leaves in the genus. It is perfect enjoyed in a cold greenhouse where it can be appreciated on the grimmest of days, but it can also be grown outside in much of this country, tucked under an evergreen or under an overhanging roof where it will get a little weather protection. It does not like to bake dry in summer. It develops something of a permanent tap root, and the key to success is to maintain deep moisture for this permanent root, whilst the corm itself is able to dry off during its summer dormancy. I can offer splendidly marked plants in 9cm pots.
