How to plant and care for Hellebores

Hellebore growing guide

As lovely as Hellebores are they are not the easiest plant to grow. I recently bought some myself and was given a growing guide with them. The following information is from both the growing guide and my own personal experience with these plants.

 

The correct climate and planting location for Hellebores in Australia

In Australia Hellebores can be grown in Victoria and Tasmania. They will grow as far north as Sydney but they are ideally suited to the colder weather of the Southern states. As you may have guessed these plants are not effected whatsoever by frosts. Hellebores do not like sandy soil or waterlogged heavy clay soils so something in between is needed. The planting position of Hellebores is important. They need to be shaded in summer and have as much sun as possible in winter. This is why people always tell you to plant them under deciduous trees.

Planting Hellebores

Hellebores have very fast growing root systems so you need to plant the as soon as possible. They put on most of their growth in winter so planting them as early as possible in the cool seasons gives them more of a chance to establish themselves. Plant them about 60cm apart and loosen the roots before planting. Incorporate organic matter into the soil before planting and water in afterwards.

Hellebore maintenance

When new growth starts to show through in late autumn remove all old growth. Late autumn is also time to feed these plants as the main growth occurs in winter. During the warm months inspect the plants for aphids. Hellebores usually need 2 to 3 years to establish before flowering will occur.

Conclusion

If you follow these instructions your Hellebores should thrive. The main point is the planting location. They really do need as much sun as possible in winter to put on a good show of flowers. Some people have told me that they need full sun but in my experience I have seen Hellebores flowering well in locations with an eastern aspect so they would only be getting full sun for half a day. Good luck!

Euphorbia characias subsp. wulfenii. An extremely tough and drought tolerant plant for Australian conditions.

Whoever owned my house before I bought it decided to put a garden bed right under the eaves outside my bedroom. This is a bit of a classic mistake as the cover of the eaves provides a rain shadow. Essentially no rain will fall on the portion of the garden bed under the eaves creating desert like conditions. I tried planting plants there and watering them with my trusty watering can but I would inevitably let the area dry out too much and they would die. Then somebody recommended that I try planting Euphorbia characias subsp. wulfenii there and I haven't looked back. The Euphorbia genus may be more well known as a weed to some (and this particular plant is restricted in W.A and the N.T)  rather than an ornamental plant but that weedy robustness is what makes the charcias species such a great plant. The soil under my eaves where this plant is growing is really sandy and dry. I do still water this plant but only once every couple of weeks and it would only get 10 litres at a time if it is lucky. Despite that lack of water and poor soil it has thrived and I would highly recommend it as a drought hardy perennial plant for people in Melbourne or even up in the central highlands of Victoria. It is said that it needs full sun but mine is planted on a Western aspect so it can deal with part shade. Although it is said to be a perennial it does get quite leggy after a few years but I have found that it self seeds quite well so there is always some new plants on the rise. Euphorbia characias is native to the Mediterranean and its milky latex sap has been used as an ancient traditional plant medicine to treat skin issues such as warts, skin cancers and tumors. The latex sap however is to be treated with caution. If you get it in your eyes it can cause significant damage. Do not ingest any part of this plant as it is toxic. There are several different cultivars that are in nurseries so if you are in the market for a low maintenance, drought tolerant plant (and don't live in W.A or N.T) then give it a go.

I find the foliage of Euphorbia characias more interesting than its flowers. The 'Black Pearl' cultivar has foliage the same shape as the one pictured below but with dark and almost black leaves.

Winter flowering tree Taiwan Cherry (Prunus campanulata)

At the NMIT Fairfield campus where I study Horticulture there is a sad looking row of Taiwan Cherry trees. Sad because the have had some bad pruning done on them but at the end of the row is the beautiful tree you see in the pictures below. Prunus campanulata is a tree native to China and Japan. According to information I've seen on the good old internet it can grow to 7m high with a spread of 7m however I can't say I've ever seen one grow to that size. Maybe in Melbourne they don't quite have the ideal conditions they require for full growth or maybe I've just been unlucky and walked past a huge specimen without looking. This beautiful tree is actually an environmental weed in New Zealand where it has spread throughout several parts of the country. Cultural notes on this tree seem to be basically the standard (ie rich and well drained soil with moist conditions) but the fact that it has escaped as a weed in New Zealand seems to suggest that it is not too fussy about its habitat. In all the cultural  notes I've found it is stated that it will grow in clay, loam or sandy soil and it also like full sun. I think that this tree would look great in conjunction with some traditional Cherry Blossom trees as it flowers at the same time.

Winter flowering plants in Parkville

It's a common misconception that plants do not flower in winter. In Melbourne this is definitely not the case and I am a great believer in winter flowering plants they provide attractive colour  in the garden when the deciduous trees have lost their leaves. Although we are now approaching the middle of winter there are lots of beautiful plants in bloom at my work. Strangely the weather has been unseasonably warm lately with several days approaching 20 Celsius after frosty mornings. The warmer temperature makes gardening a lot more comfortably and to be honest I haven't hated the frosty mornings because, in Parkville, I have had lots of physical morning tasks that keep me warm. Of all the winter flowering plants my favorite has to be the Magnolia trees. There is one large specimen in Parkville that, so far, has not lost its buds to hungry possums. Last year it only had a handful of flowers due to bud loss but its looks as though it will fully flower this year.



Magnolia soulangiana. This could be my favorite tree and the flowers are just starting to pop.





The same tree as above. You can see how many flowers have already opened. This time last year we only had about half of what is shown here across the whole tree. Notice the sunny blue winter sky.






Hellebores are also starting to open. We have several different types in the Parkville garden.





Another Hellebore. Not sure of the variety but I'm fairly sure we sourced them from 'post office farm nursery' which is a grower up in Woodend near my home. They have open days on Sundays this time of the year. A link to their website is below.





The annual bed is loaded with new plants. I planted Kale, Violas, Pansies, Cinerarias and Stocks. I also cannot bring myself to remove that small bunch of violets that have self seeded in the front of the bed. In a mont or so this bed should look fantastic.






I discovered this plant in flower whilst pruning some nearby Wisteria. It is called Luculia and its perfume smells amazing. 





The good old Salvia plant keeps flowering year round not just in winter.





Several bulbs have popped up out of the ground and this Jonquil seems to have beaten them all and flowering first.





Below is a Strelitzia or 'bird of paradise'. These plants are a common sight in many Melbourne gardens. They are tough plants which do not need much water.





Another one of my favs is the Kniphofia plant pictured below. The ones I propagated and planted at home have still not flowered but the ones in Parkville are in full bloom.

Euryops pectinatus or the Yellow daisy bush. A classic plant for adding colour to your garden in winter.

In winter the most showy plant I have in my garden in terms of masses of colourful plants is my Euryops pectinatus. Euryops are a classic perennial plant that can be found in many Australian gardens. It has some degree of frost tolerance and tolerates a certain amount of dryness. This perennial is native to South and Central Africa and the name Euryops comes from the Greek Eurys (large) and ops (eye). There are several different varieties of Euryops but I would say that most can grow to about 1.7 high and 1.7 metres wide. I cut mine back after flowering but I let it go for a couple of years and it has gone a bit leggy. I have read that they strike quite easily from cuttings so I will try and propagate some that way and start them off again. It has a silvery sheen to its foliage which some say combines well with Wormwood which has a similar leaf. Here in Australia this plant is probably considered boring by some because it is extremely common but I love it as its is fairly low maintenance and provides some vivid colour to my garden in the cooler months. Among the common names for Euryops pectinatus are Yellow daisy bush or Golden daisy bush.

Look at all those flowers. You would be forgiven for thinking that it is Spring.
