Every greenhouse gets an Oxalis sooner or later

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 […]

Schefflera, Queensland Umbrella trees

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 […]

These are here, there, everywhere

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 […]

Echeverias, houseleeks from sunnier climes

“Why are you growing houseleeks in your greenhouse?” said a friend looking at some Echeverias I had around the base of a Bougainvillea.

These are long stems festooned with numerous orange ‘flowers’ and so called as they so closely resemble brilliantly coloured paper decorations.

Spider lilies and Peruvian Daffodils

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 […]

Apios, hopniss, a forgotten gem

Apios is one of those forgotten greenhouse gems seldom come across nowadays. It was once very popular in late Victorian times for the violet scent from the small racemes of purplish flowers. However after the First World War the shortage of labour and its slight tenderness made this plant unattractive. Indeed in the UK it […]

Long flowering guaranteed (Polygala)

Polygala x Dalmaisiana is a superb choice for conservatories and cool greenhouses with beautiful purple pea like blooms throughout much of the year. These decorative flowers are produced almost continuously along the ends of lax stems of attractive grey green evergreen foliage. Not so much an impressive centre piece perhaps but excellent as the supporting […]
