University Gardener Was Sinning

The quintessential greenhouse flower is Gloxinia. This tropically splendid beauty produces wonderful displays of luxuriant blooms. Each large almost wineglass shaped flower has fleshy petals with a velvety sheen. As the petals fade the flower drops leaving an attractive star shaped calyx. These were discovered in Brazil and South America and introduced to our Greenhouses, […]

Commelina, Blue Spider-wort, Day-flower

With gorgeous sky blue flowers all of summer the Blue Spider-wort is an ideal plant for a cool greenhouse. True it’s a tad lax and can flop if not supported and the waist high stems of lanceolate leaves are not exactly stunning. However continuous displays of gentian blue flowers redeems all. As these lovely blooms […]

The bells, the bells… Campanulas

As often found in an alpine house as a greenhouse many Bellflowers, Campanulas, are rock garden and border plants. However some low growing and prostrate species are delightful under cover for filling in around the base of taller plants with their verdant foliage and masses of cool blue flowers. Campanula is an interesting, floriferous and […]

Common & uncommonly good

Lobelia is a world-wide genus of uncommonly good glasshouse flowers, indeed almost every member of this large genus has attractive blooms, often coming in masses, usually in a shade of blue. Lobelia has shrubby, evergreen and herbaceous members, annuals, biennials and perennials, there are even a few hardy sorts for the outdoor garden. However the […]

Named after ashes this is not at all dull

Some plants, and oddly rather many glasshouse plants, have somewhat misleading common names. This gem has perversely come to be known as Cineraria though it is not a Cineraria but a Senecio. Cinerarias are so named for their soft white downy leaves like cineres the Latin for ashes. Some Senecios also have white or grey […]

Not Tyranosaurus but Begonia

I have written before of the tremendous value in our greenhouses from the Begonia tribe though I was mostly talking about their huge range of floral varieties. Now I am waxing even more enthusiastically about the foliage varieties of Begonia particularly B. Rex-cultorum. Rex is a term not often employed in botanical Latin and as […]

The Friendship Plant or Queen’s Tears

The Friendship Plant is a very tough house plant, and an even better choice for the glasshouse. Attractive clumps of foliage erupt nodding spike after spike of pink bracts, each cascading green petals with a bright blue edge and golden anthers. These continue to appear over a long period. It will withstand neglect, and resists […]

The sound of rubbing stems and Dove’s dung

Amongst the benefits a glasshouse offers can be year round flowers for cutting. Cut flowers are more expensive to purchase than most fruits and vegetables so really deserve some attention. And one of the best cut flowers for sheer endurance once cut is the Chincherinchee. Ornithogalum thyrsoides is a bulbous plant of the Lily family […]

Charming, cheerful and inexpensive

Suitable for the less attentive greenhouse gardener and amongst the toughest houseplants you can find are the many members of the Commelinaceae family mostly hailing from South America. Indeed you may once already have grown the trailing Wandering Jew as this is one of those rugged plants entrusted to children. However that is but one […]
