Known as the Lady’s Slipperand hardly classed as tuberous rooted, yet this is one of the loveliest of all semi- to grace our gardens. In gardens which can provide some shade or where a semi-moist can be found by the side of a lake or stream, the Cypripediums will produce their delightfully veined and foliage with the utmost abandon. They must have a soil containing a large quantity of mould, they do in fact like to have their feet in moist, cool soil and their heads in sunshine or partial sunshine.
I have found that nowhere do they grow better than when planted under pine trees, not in a wood thick with these times, but under a single tree which will provide partial shade and a soil packed with pine needles. If it be a sandy, well-drained soil, so much the better. Some sand should be dug in at planting-time and as much humus as can be found, anything in the way of rotted, decayed bracken, peat and very well-rotted manure. And lime they do not like in any quantity.
They should be planted with their fleshy alstomeria-likeonly just beneath soil-level. In this and all other respects they are very like the American Cowslips with which they should be planted. And plant also the North American , which looks so attractive with its ebony black and vivid green foliage. If natural conditions cannot be found then they may be artificially made by working into the soil as much humus as can possibly be found, and planting in a partially shaded .
- Cypripediuns acaule. An expensive but outstandingly beautiful species bearing a bloom -with pink petals, green sepals and a crimson veined slipper, a combination of great beauty for flowering throughout early summer.
- C. ealceolus. This is the native English Lady’s Slipper and is the exception to the rule of not liking lime, for it thrives on it like perennial Scabious. Bears its bloom on 2-in , the slipper being vivid yellow, the petals brown.
- C. pubeseens. The tallest-growing species which love the sunshine more than most. The green and chocolate petals are of great length, the slipper being rich greenish yellow. Bears its flowers throughout June.
- C. Reginae. Bears its flowers throughout May on long stems, and is rather more difficult to get going than most varieties. The bloom has pure white petals with a bright rose-coloured slipper.
