Figs really are the most curious of glasshouse fruits. These are very ancient crops developed from the wild form in western Asia where these were pollinated by a tiny Chalcid wasp that evolved to depend on the fig and vice versa. The way these wasps interact with the flowers, which are tiny and hidden inside […]
Also known as Fringe flowers and Poor man’s orchids Schizanthus are a glorious way of filling a glasshouse with summer colour. Coming from S. America this small genus related to potatoes derives both common and scientific names from pretty pansy like blooms. These have split corollas and look much like orchids, and even more like […]
This charming greenhouse beauty was described by Linnaeus as “Mere weeds, found on old walls and stony ground, they have no beauty and are of the easiest culture”. Back then he named it as a Parietaria it then became a Helxine, and now it is Soleirolia soleiroli. The common names are even more prolific, it […]
Now here’s a genus I promise you are going to grow at least one species of some day. You may already have one. A delightful purple leaved miniature clover like creeping plant, Yellow Oxalis, Oxalis corniculata. It’s one of the commonest of greenhouse weeds, which means it’s seldom thought desirable. Okay, it does spread invasively […]
The Queensland Umbrella tree, Schefflera is an evergreen greenhouse or conservatory shrub come small tree distantly related to ivy. Given good conditions a plant under cover may flower and berry though it’s for the somewhat hand shaped and handsome foliage this is cultivated. Originally from Australasia these distinctive ornamental shrubs have proved popular in subtropical […]
Okay I admit of all glasshouse and conservatory plants Ficus benjamina might be considered one of the less flamboyant. Indeed this is just a foliage plant, mind you what lovely clean glossy foliage and on such delightfully neat shrubs. Tough and reliable benjaminas have long proved popular with gardeners and indoor decorators just because they […]
“Why are you growing houseleeks in your greenhouse?” said a friend looking at some Echeverias I had around the base of a Bougainvillea. An easily made mistake for these are a fine example of parallel evolution. Houseleeks are temperate plants designed to survive conditions as harsh and impoverished as crevices of dirt on rock-piles or […]
Okay of the many tender glasshouse plants Saintpaulias can be one of the trickiest. Yet almost everyone knew an aunt with a massive old African violet enduring on for years blooming almost perpetually. It will have been the original blueish violet flowered Saintpaulia ionantha, and it was probably set on a table in some north […]
Happier as warm greenhouse specimens than as houseplants are the gorgeously flamboyant Peacock and Zebra plants, the Calatheas, from Tropical America. Oh you can force some such as C. insignis or C. zebrina to live in a well lit house but most are much happier in a warmer more humid atmosphere, it’s their tropical jungle […]
For a wonderful display in your greenhouse or conservatory all winter through you just cannot beat Chinese Lanterns. These are long stems festooned with numerous orange ‘flowers’ and so called as they so closely resemble brilliantly coloured paper decorations. Also known as Bladder Cherries Physalis alkekengi really are most distinctive and have been grown since […]
You need a heated greenhouse or conservatory where the temperature never drops below 20°C/70°F to safely grow these rare bulbous plants known in Latin as Hymenocallis. Very closely related to Amaryllis (note the similar strap like leaves) these are amongst the most beautiful of flowers carrying a heavy vanilla perfume to add to their pristine […]
I recently wrote that for a glasshouse watercress was the most nutritious crop you could grow, and that still stands. However the huge productive capacity under cover can be more efficiently harnessed to produce even more healthy nutrition. And a very succulent, delicious and tasty increase this is; from growing baby salad leaves. You see […]
