Tried and True – Helleborus orientalis

Helleborus orientalis - gentle and understated garden performers

Helleborus orientalis - gentle and understated garden performers

  • Winter flowering.
  • Require very little care and maintenance.
  • An undemanding plant for filling spaces.
  • Very hardy evergreen.

 

Helleborus orientalis are not from the exotic Orient. In fact they are native to areas of Turkey and Greece which may explain their tough constitution. They are often called winter roses, presumably because they flower in winter and are easy to grow. Their link to roses is as remote as their link to the Orient. They are an enormously obliging and gently understated plant, with pretty cup flowers which face downwards. These are not plants for deep shade – keep them to the margins of bush or woodland or even the open because they need reasonable light levels and can cope with full sun. Easy-care plant and leave specimens, they don’t appreciate being lifted and divided but are happy to be left to their own devices with the occasional feed.

There has been an explosion of different hellebore cultivars on the market in recent years, many of them orientalis hybrids. Some of the frilly doubles are very pretty, some are just average doubles. The really good dark maroon and slate colours will be better if you live inland and can give colder conditions. The simplest seedling forms are just single flowers in shades of pink, white and green, with or without freckles on the inside. Floating blooms in a glass bowl is the usual method of displaying them once cut.

Helleborus orientalis sets seed freely but the seed will not come true to its parent and you will get considerable variation. Push hoe or weed out surplus germinating seed to prevent too much competition. Aphids can make the spent flower head their home so it is often advisable to deadhead once at the end of the flowering season in spring. We cut off all the old foliage in mid autumn which gets rid of any lingering aphids and also exposes the pretty flowers to view before the fresh foliage appears.

Tried and True: Lachenalia aloides

Lachenalia aloides

Lachenalia aloides

• The easiest lachenalia to grow.
• Widely available, from many other gardeners if not from every garden centre.
• Bright winter colour.
• Often sold as Lachenalia Pearsonii.

In the gloom of winter when the main colour comes from pink camellias, the early flowering lachenalias ring a colour change to orange and red. Whether you consider this form of aloides to be garish or cheerful depends on your personal taste. It is the most common lachenalia in New Zealand and is often referred to as Pearsonii. It has two strappy leaves per bulb, usually with burgundy spots. These are South African bulbs which thrive in areas which have winter rainfall although even the toughest aloides will not want to be out in hard frosts. Lachenalias have a long dormancy period so are easy to lift and divide.

Try underplanting citrus trees to repeat the colour, or we find it also combines well with the green, mounding hillocks of our native scleranthus biflorus. It will combine equally well with any predominantly green scene to add a bright spot.

Tried and True: Ligularia reniformis

  • img_6451* Impressive in size and lush appearance.
    * Evergreen.
    * Looks tropical but can withstand light frost and cool winters.
    * Widely available for sale.

 In this country, as in Australia, we all know this plant as the tractor seat ligularia, which says quite a bit about our rural origins. I guess the leaves could be said to resemble a traditional tractor seat in shape and when growing strongly, getting pretty close in size. We have almost made this plant our own in New Zealand and have certainly pushed the boundaries of where it is grown – it is technically sub tropical and from East Asia. In warm areas, it gets considerably larger but even in cooler areas with a bit of frost, it makes an impressive clump a metre across and a metre high over time. It will need more protected conditions where frosts are more frequent but it is happy in high shade and on woodland margins. Typical of any perennial, it likes rich, well cultivated soil with plenty of humus and good moisture levels. While not immune to the munching ways of slugs and snails, it is nowhere near as tasty as hostas and we have never worried about pests or diseases on our plants. It is grown for its foliage and if you have the space for a large and impressive plant with large and impressive leaves (think giant water lily pads), it is a good addition and easy to contrast with a whole range of other plants. Reniformis is widely available in garden centres.

Tried and True: vireya rhododendrons Jiminy Cricket, Saxon Glow and Saxon Blush

Jiminy Cricket - the hardiest of any vireya we know

Jiminy Cricket - the hardiest of any vireya we know

  • The hardiest of the vireya family.
  • Tidy, compact growth around 75cm high.
  • Widely available.
  • Flower freely over a long period of time.

Siblings, these three cultivars. The breeder, Os Blumhardt, gave us seed of the cross and one plant grew so well we put it into production with his agreement. We called it Jiminy Cricket because the flowers are held upright and as singles, reminding one of the original Jiminy Cricket’s eyes swivelling on stalks. The remaining plants with Os also grew well and in due course another nursery took two and named them Saxon Glow and Saxon Blush. Glow is a little redder, Blush is a little paler pink while Jiminy is more coral orange coloured but they all have similar habits of growth. They are funny dense little plants with stiff, upwardly pointed leaves. And hardiness in colder, wetter conditions where most vireyas would promptly curl up and die – that is their biggest attraction of all. This is not to say that they will take bog, repeated heavy frosts or snow. They are just hardier than any other vireya we know so are a good choice for very marginal conditions. They make a corker little hedge – we have a semi circle planted beneath a mandarin tree and after close to a decade, they are still bushy and only about 60cm high. Vireyas are easy to strike from cutting so patient gardeners may just buy one plant and build up the numbers for a hedge.

Tried and True: Crassula ovata or the Jade Plant

The Jade Plant or Crassula ovata

The Jade Plant or Crassula ovata

  • Grows like a natural bonsai.
  • Flowers in late autumn and winter.
  • Widely available and dead easy to increase at home.
  • Optimistically called the Money Plant sometimes.
  • Apparently good for feng shui.

This crassula comes from a very large family and has undergone a number of name changes – the current choice seems to Crassula ovata. But it is commonly known as the Jade Plant. In near frost free areas, it is fine as a garden plant but inland, it will need some protection. The dry border under the eaves of the house may be an option, or a container brought under some cover in winter. Frosts will destroy the flowers and can burn the fleshy leaves, even kill the whole plant in bad cases. Being succulent, it doesn’t want wet feet, either. In return, the crassula will reward you by being genuinely easy care and undemanding and putting on a very pretty floral display in the gloom of early winter. I have never seen it more than 90cm high but it develops into a naturally characterful, gnarly looking plant with relative speed. To get more plants, just cut a branch off. Let it dry for a few days and then stick it in some potting mix or good garden soil. Bingo, it will grow roots, just as long as you don’t let it get too wet in the meantime or it may rot. This is a good plant for children to try growing – get them to put in cuttings now and the plants should be well established as Christmas presents for grandparents. Be generous and put in larger cuttings, whole branches even, for more impressive results.
