The Forest Garden weekend course starts on Friday and while thinking about propagation, I decided to have a little tidy up of some of the seedling trees & shrubs I’ve grown. I brought a lot of seed back from the UK last year, from the Agroforestry Research Trust (Martin Crawford) and an online site called Tree Seeds Online (love a name that says what it does, eh?).
The Sambucus nigra (European elder) was from TSO. We’ve had elders in Australia since European settlement, but it doesn’t hurt to mix up the gene pool, so these little guys will help do that. I feel an elder-dominated hedge coming on, don’t you. I guess I’ll have to make more cordial each November. Nice. 🙂
Aronia melanocarpa is the North American Black Chokeberry. Seed from the Agroforestry Research Trust. Aronia melanocarpa grows to a couple of metres high & wide and is also a prime hedge plant. It can spread through suckering so a little observation and maintenance is needed there – possibly from a mower! The berries are black when mature and highly astringent (hence the name chokeberry!) so are often used for jams and jellies rather than eating direct. I planted about 24 seeds and have 6 healthy plants – there is definitely an attrition rate when growing from seed, but that does make it all the more satisfying when you get good results.
Hippophae rhamnoides (front of the LHS box) is commonly called sea buckthorn and is a common coastal plant in northern Europe. I have a couple of very healthy specimens growing near the spoon drain that feeds the top dam. Those came from John Ferris’ Forest Garden Nursery in Melbourne and are cranking along. I’d like to put more in, though, and also having different genetic material can only be a good thing. As well as fabulous bright orange fruit (which grows directly on the branch), sea buckthorn is a Nitrogen fixer from the Elaegnaceae family. The fruit contains high amounts of Vitamins C and E, carotenoids, flavonoids and more Vitamin B12 than any other fruit. So far, I’ve only grown two from seed. They are dioecious (separate male and female plants) but you can’t sex them until they flower, which can take up to 3 years. Fingers crossed for a boy & a girl, right? Meantime, I’ll keep trying to grow more!
The tall guy at the front left of the RHS box is Amelanchier lamarckii – originally from North America but now widely naturalised in Europe. It is one of the more popular members of the diverse Amelanchier family and is variously known as Juneberry, Serviceberry or Shadbush in different parts of North America. Did I mention why using common names is fraught with problems and we should learn a few scientific names so we can be sure we’re all talking about the same thing? A. lamarckii can grow to 5-6 metres in ideal conditions, and can be used as a screening or hedge plant. The berries are black when mature and very sweet. They are usually ripe in June in the US; hence the Juneberry moniker.
The other little guys in the RHS box are Cornus mas – Cornelian Cherry. I bought one from Diggers years ago but it died, so I’m started from seed this time. Cornus mas is widespread across Asia and Europe and grows up to 4 m high. Fruits are astringent on the tree and only fully ripen when they’ve fallen. They taste like a cross between sour cherry and cranberry and are used across Europe for making jams, jellies & liquers. They are also an important Chinese medicine plant.
Want some plant trivia? The wood of C. mas is so dense that it sinks in water! Yep – wood that won’t float. It is therefore great for use in handles, tools, etc and the Greeks preferred it for spears, javelins and bows. Cool. 🙂
