OSIER A wonderful foodplant. Ten cuttings
Availability: NOW


Osier Willow cuttings S. viminalis

Years ago we planted a stick that was floating down a river in Wiltshire.  That was in 1954! It grew – rapidly – producing a wealth of leaves.  We tried it as a foodplant and discovered that not only did British species do well on it, but exotic silkmoth larvae as well.

This stick was the daddy of hosts of willow thickets that we have established in Dorset, Cornwall and in France.

Osier is Basket Willow, the flexible essential for basket weaving. It makes a wonderful woven hedge. It can form living sculptures. Winter or summer, Osier makes wonderful screens and windbreaks. Cover for wildlife and game. Osier is grown as a crop for energy production. In short it is a blessing to the environment, and very pleasant on the eye in landscaping schemes.

 We are offering a bunch of 10 cuttings for you to try not only as probably the most universal foodplant for larvae, but a great addition to your garden and grounds. 

Probably the easiest cuttings to strike and grow. You simply push them into the ground, during autumn or spring. Leaves will appear within the first fortnight if planted in spring, roots quickly follow. In the first year they will more than double in size. Next year, in normal drought free conditions,  if you winter prune very hard, you will have perhaps 2 metres of growth on every branch, providing masses of foodplant. You may even be able to feed some in the first year.

You can store cuttings before planting, either in a polythene bag in the fridge, or standing in water. In water they often start to root. It is advisable to plant them before the roots actually burst out of the bark.

 

This plant is a complete success story – you will be pleased you tried it!

Milk Parsley Peucedanum palustre  Packet of seed
Availability: NOW


Milk Parsley Peucedanum palustre  Packet of seed

The natural foodplant of the English Swallowtail butterfly, in its fenland habitat, and for Papilio machaon machaon, the nominate race in Sweden. This plant encourages egg-laying like no other, and is often the chosen foodplant of the European Papilio machaon gorganus in other parts of Europe,   

The leaves look a little like Carrot. This is a marsh plant that likes growing with its roots in water. Potted plants can be stood in a tray that is always full of water. Otherwise grow on the edge of a pond, or create a non-draining habitat around the roots.

Larvae from eggs laid on Milk Parsley can be changed to Fennel or other foodplants, in cases where there is not enough Milk Parsley to raise a host of hungry caterpillars. However, our Swedish breeder tells us that in that country, machaon does much better when fed only on Peucedanum.

Seeds sown in autumn are capable of producing plants large enough for egg-laying in the following summer.

Easily grown from seed, in a tray of peaty compost. Seed does not keep for many weeks, so don't store the seed: sow without delay.

KOKUSO 21 Mulberry A group of 5 robust cuttings.
Availability: NOW


KOKUSO 21 Mulberry A rarity! A group of 5 robust cuttings.

This sericultural form of Mulberry has been developed in Asia for its large leaves with high nutrition as food for Silkworms. Not generally available for sale, we are offering a limited number of robust cuttings in groups of 5. 

The cuttings will develop roots and leaves if put into compost, preferably with manure. Never let the compost dry. Rooting may be assisted if dipped in hormone rooting powder. Mulberry cuttings take longer to root than Willows and Osiers, which are very rapid. Hard winter pruning is repaid with amazing growth, which can reach 1-2 metres on every branch in the following summer.

This is a rare shrub, seldom seen in Northern Europe.

Complete MINI SILK FARM
Availability: NOW


THE MINI SILK FARM

A complete outfit for rearing silkworms from egg to cocoon, and reeling your own raw silk. Everything is provided: a small batch of eggs, food for the entire life of 20 silkworms, all the rearing equipment, detailed educational documentation and instructions, and a simple reeling device.

There is even a small bag of cocoons so that you can practise reeling, and don't have to wait to rear the cocoons from the egg.

Normally Silkworms feed on Mulberry leaves. This is an uncommon tree that is not always readily available, so we are providing a substitute food, which is a powder that comes with the necessary instructions for preparing the artificial diet in the kitchen. You will have a supply of fresh food always available for the silkworms throughout their life of about a month.

The Mini Silk Farm can be bought at any time of the year. The eggs are stored in a fridge until incubation. Although rearing in summer is easier because of temperature, you can rear silkworms almost throughout the year, if you can keep them at about 25º-28ºC. Eggs supplied in winter will need to be refrigerated for 8-12 weeks before incubation.

The instructions guide you through easy rearing, preparation of the artificial diet and the reeling process. The Mini Silk Farm is fun and unusually educational.

Peruvian Black Beauty Stick Insect Peruphasma schultei 6 nymphs
Availability: October


Peruvian Black Beauty Stick Insect Peruphasma schultei,

Very attractive insects, easy to keep in a ventilated cage, feeding on Privet. They enjoy a spray most days with tepid water. It is best not to let young children have the insects walking on their hands, because they have a defence mechanism that produces a pungent fluid when they are alarmed. Sometimes an irritant. The insects are otherwise completely harmless. Their appearance in contrasting black and scarlet is an interesting example of colours that warn off predators. 

This species comes from just a small area in Peru and are not known from anywhere else. They are very special.
