Physocarpus
Anyone experience of growing it in lousy clay soil? The position is a
couple of metres from corner 2-metre high south/south-east facing brick walls in south Hampshire. The garden is at a 4-years old new-build house (ie builder's rubble on top of clay subsoil...). I originally dug out a hole about 25 cm deep and 30 across, filled with good JI3, and put in an Acer palmatum atropurpureum (as my daughter likes the colour and leaf form). It lasted 3 years, but was never happy, and finally died last winter. I guess there could have been a sump effect. I wondered about replacing it with another maple, but it's a fairly expensive way to kill a plant. Looking around, Physocarpus opulifolius "Lady in red" seems a reasonable choice as a substitute. Good colour and interesting leaf shape. I'll make the hole a little bigger and deeper before I put anything in. Any other suggestions for small/medium brown/purple-leaved shrubs/trees in that situation? -- Jeff |

I did consider it, but in a couple of years a small boy crawling around the garden will not make mum happy when he squashes the fruits all over himself and then the carpet! -- Jeff |

(don't know the answer to actual question as I don't have clay soil) I'd also suggest looking at Gleditsia triacanthos Ruby Lace. Apparently they're tolerant of clay. And unlike Robinia, which they resemble, bits don't break off them easily in high winds! Thanks Sacha. I've never heard of it, but it looks fine to me. I like it's mop-head shape, but don't what the Junior Management will make of it. -- Jeff |

(don't know the answer to actual question as I don't have clay soil) Nor do I, but I can disrecommend Cotinus coggryia. I grow it, but it has suffered badly from the recent wet years, even on my sandy soil. It is a drought-lover. I had an Acer palmatum, but it didn't even last that long. They are definitely delicate - Sambucus sounds a much better bet. Regards, Nick Maclaren. |

But, according to it (and quite a few other websites) I was surprised to find that Physocarpus is poisonous in all its parts. That's not something I would ever had expected, as "poisonous" and "Rosaceae" are not something I usually put together (other than for some cyanogenic seeds). The Prunus x cisterna also looks nice, but its common name (sand cherry) seems to suggest that it won't like heavy clay soil. And it's about as "cheap" as acers of a similar size... Do make sure you plant with lots of good compost. This will help the plant establish a decent root system before it ventures forth and discovers your lousy - and limey - clay soil. I'm slowly working towards the idea that a much bigger hole with well-draining soil will be required, if I want anything which normally likes good drainage to survive. -- Jeff |

That's true, but another exception is common laurel. Whenever I prune and shred my cotoneaster, there is a powerful smell of bitter almonds, which makes me think that eating its leaves might be a mistake :-) I'm slowly working towards the idea that a much bigger hole with well-draining soil will be required, if I want anything which normally likes good drainage to survive. Grrk. In clay soil, even that doesn't help, as the hole just fills with water. You need some way to take it away from the bottom of the hole. Regards, Nick Maclaren. |

That's true, but another exception is common laurel. Whenever I prune and shred my cotoneaster, there is a powerful smell of bitter almonds, which makes me think that eating its leaves might be a mistake :-) Laurel All parts of the laurel are poisonous, though there are few reported cases of serious illness. The berries are the most likely to attract children. A case in Bolton in 2000 involved a child being taken to hospital with drowsiness which was diagnosed as having been caused by eating or chewing a laurel berry. However, there is no doubt it is extremely dangerous if very much is eaten as it contains cyanide. The leaves and stems contain small quantities of cyanide. Bundles of crushed leaves were used in ancient times to poison wells. Emperor Nero used laurel water to poison the wells of his enemies in Rome. Laurel water (distilled from the fresh leaves of the laurel) was used in Victorian times as a medicine. However, there is a case of a death reported when it was mistaken for an alcoholic spirit and drunk by a chemist's cleaner. Effectively, it contains hydrogen cyanide. Crushed leaves were used by butterfly collectors (in a closed jar) to kill the butterflies. Commentators advise against burning the leaves and clippings as they also give off cyanide. It would be wise not to do so or to keep well away from the smoke. There are cases, however, where people have become ill through inhaling the vapours from the shredded leaves, including professional gardeners who have transported the shredded leaves and branches in an enclosed van. It would be advisable not to shred laurel leaves. |
